  • In Confab : Paul Elsner

    Posted on January 23rd, 2014 Jo No comments

    Dr Paul Elsner of Birkbeck College at the University of London gave up some of his valuable time for me today at his little bijou garret-style office in Bloomsbury in Central London, with an excellent, redeeming view of the British Telecom Tower. Leader of the Energy and Climate Change module on Birkbeck’s Climate Change Management programme, he offered me tea and topical information on Renewable Energy, and some advice on discipline in authorship.

    He unpacked the recent whirlwind of optimism surrounding the exploitation of Shale Gas and Shale Oil, and how Climate Change policy is perhaps taking a step back. He said that we have to accept that this is the way the world is at the moment.

    I indicated that I don’t have much confidence in the “Shale Bubble”. I consider it mostly as a public relations exercise – and that there are special conditions in the United States of America where all this propaganda comes from. I said that there are several factors that mean the progress with low carbon fuels continues to be essential, and that Renewable Gas is likely to be key.

    1. First of all, the major energy companies, the oil and gas companies, are not in a healthy financial state to make huge investment. For example, BP has just had the legal ruling that there will be no limit to the amount of compensation claims they will have to face over the Deepwater Horizon disaster. Royal Dutch Shell meanwhile has just had a serious quarterly profit warning – and if that is mostly due to constrained sales (“Peak Oil Demand”) because of economic collapse, that doesn’t help them with the kind of aggressive “discovery” they need to continue with to keep up their Reserves to Production ratio (the amount of proven resources they have on their books). These are not the only problems being faced in the industry. This problem with future anticipated capitalisation means that Big Oil and Gas cannot possibly look at major transitions into Renewable Electricity, so it would be pointless to ask, or try to construct a Carbon Market to force it to happen.

    2. Secondly, despite claims of large reserves of Shale Gas and Shale Oil, ripe for the exploitation of, even major bodies are not anticipating that Peak Oil and Peak Natural Gas will be delayed by many years by the “Shale Gale”. The reservoir characteristics of unconventional fossil fuel fields do not mature in the same way as conventional ones. This means that depletion scenarios for fossil fuels are still as relevant to consider as the decades prior to horizontal drilling and hydraulic fracturing (“fracking”).

    3. Thirdly, the reservoir characteristics of conventional fossil fuel fields yet to exploit, especially in terms of chemical composition, are drifting towards increasingly “sour” conditions – with sigificant levels of hydrogen sulfide and carbon dioxide in them. The sulphur must be removed for a variety of reasons, but the carbon dioxide remains an issue. The answer until recently from policy people would have been Carbon Capture and Storage or CCS. Carbon dioxide should be washed from acid Natural Gas and sequestered under the ocean in salt caverns that previously held fossil hydrocarbons. It was hoped that Carbon Markets and other forms of carbon pricing would have assisted with the payment for CCS. However, recently there has been reduced confidence that this will be significant.

    Renewable Gas is an answer to all three of these issues. It can easily be pursued by the big players in the current energy provision system, with far less investment than wholesale change would demand. It can address concerns of gas resource depletion at a global scale, the onset of which could occur within 20 to 25 years. And it can be deployed to bring poor conventional fossil fuels into consideration for exploitation in the current time – answering regional gas resource depletion.

    Outside, daffodils were blooming in Tavistock Square. In January, yes. The “freaky” weather continues…

  • But Uh-Oh – Those Summer Nights

    Posted on January 20th, 2014 Jo No comments

    A normal, everyday Monday morning at Energy Geek Central. Yes, this is a normal conversation for me to take part in on a Monday morning. Energy geekery at breakfast. Perfect.

    Nuclear Flower Power

    This whole UK Government nuclear power programme plan is ridiculous ! 75 gigawatts (GW) of Generation III nuclear fission reactors ? What are they thinking ? Britain would need to rapidly ramp up its construction capabilities, and that’s not going to happen, even with the help of the Chinese. (And the Americans are not going to take too kindly to the idea of China getting strongly involved with British energy). And then, we’d need to secure almost a quarter of the world’s remaining reserves of uranium, which hasn’t actually been dug up yet. And to cap it all, we’d need to have 10 more geological disposal repositories for the resulting radioactive spent fuel, and we haven’t even managed to negotiate one yet. That is, unless we can burn a good part of that spent fuel in Generation IV nuclear fission reactors – which haven’t even been properly demonstrated yet ! Talk about unconscionable risk !

    Baseload Should Be History By Now, But…

    Whatever the technological capability for nuclear power plants to “load follow” and reduce their output in response to a chance in electricity demand, Generation III reactors would not be run as anything except “baseload” – constantly on, and constantly producing a constant amount of power – although they might turn them off in summer for maintenance. You see, the cost of a Generation III reactor and generation kit is in the initial build – so their investors are not going to permit them to run them at low load factors – even if they could.

    There are risks to running a nuclear power plant at partial load – mostly to do with potential damage to the actual electricity generation equipment. But what are the technology risks that Hinkley Point C gets built, and all that capital is committed, and then it only runs for a couple of years until all that high burn up fuel crumbles and the reactors start leaking plutonium and they have to shut it down permanently ? Who can guarantee it’s a sound bet ?

    If they actually work, running Generation III reactors at constant output as “baseload” will also completely mess with the power market. In all of the scenarios, high nuclear, high non-nuclear, or high fossil fuels with Carbon Capture and Storage (CCS), there will always need to be some renewables in the mix. In all probability this will be rapidly deployed, highly technologically advanced solar power photovoltaics (PV). The amount of solar power that will be generated will be high in summer, but since you have a significant change in energy demand between summer and winter, you’re going to have a massive excess of electricity generation in summer if you add nuclear baseload to solar. Relative to the demand for energy, you’re going to get more Renewable Energy excess in summer and under-supply in winter (even though you get more offshore wind in winter), so it’s critical how you mix those two into your scenario.

    The UK Government’s maximum 75 GW nuclear scenario comprises 55 GW Generation III and 20 GW Generation IV. They could have said 40 GW Gen III to feed Gen IV – the spent fuel from Gen III is needed to kick off Gen IV. Although, if LFTR took off, if they had enough fluoride materials there could be a Thorium way into Gen IV… but this is all so technical, no MP [ Member of Parliament ] is going to get their head round this before 2050.

    The UK Government are saying that 16 GW of nuclear by 2030 should be seen as a first tranche, and that it could double or triple by 2040 – that’s one heck of a deployment rate ! If they think they can get 16 GW by 2030 – then triple that by 10 years later ? It’s not going to happen. And even 30 GW would be horrific. But it’s probably more plausible – if they can get 16 GW by 2030, they can arguably get double that by 2040.

    As a rule of thumb, you would need around 10 tonnes of fissionable fuel to kickstart a Gen IV reactor. They’ve got 106 tonnes of Plutonium, plus 3 or 4 tonnes they recently acquired – from France or Germany (I forget which). So they could start 11 GW of Gen IV – possibly the PRISM – the Hitachi thing – sodium-cooled. They’ve been trying them since the Year Dot – these Fast Reactors – the Breeders – Dounreay. People are expressing more confidence in them now – “Pandora’s Promise” hangs around the narrative that the Clinton administration stopped research into Fast Reactors – Oak Ridge couldn’t be commercial. Throwing sodium around a core 80 times hotter than current core heats – you can’t throw water at it easily. You need something that can carry more heat out. It’s a high technological risk. But then get some French notable nuclear person saying Gen IV technologies – “they’re on the way and they can be done”.

    Radioactive Waste Disposal Woes

    The point being is – if you’re commissioning 30 GW of Gen III in the belief that Gen IV will be developed – then you are setting yourself up to be a hostage to technological fortune. That is a real ethical consideration. Because if you can’t burn the waste fuel from Gen III, you’re left with up to 10 radioactive waste repositories required when you can’t even get one at the moment. The default position is that radioactive spent nuclear fuel will be left at the power stations where they’re created. Typically, nuclear power plants are built on the coast as they need a lot of cooling water. If you are going for 30 GW you will need a load of new sites – possibly somewhere round the South East of England. This is where climate change comes in – rising sea levels, increased storm surge, dissolving, sinking, washed-away beaches, more extreme storms [...] The default spent fuel scenario with numerous coastal decommissioned sites with radioactive interim stores which contain nearly half the current legacy radioactive waste [...]

    Based on the figures from the new Greenpeace report, I calculate that the added radioactive waste and radioactive spent fuel arisings from a programme of 16 GW of nuclear new build would be 244 million Terabequerel (TBq), compared to the legacy level of 87 million TBq.

    The Nuclear Decommissioning Authority (NDA) are due to publish their Radioactive Waste Inventory and their Report on Radioactive Materials not in the Waste Inventory at the end of January 2014. We need to keep a watch out for that, because they may have adapted their anticipated Minimum and Maxmium Derived Inventory.

    Politics Is Living In The Past

    What you hear from politicians is they’re still talking about “baseload”, as if they’ve just found the Holy Grail of Energy Policy. And failed nuclear power. Then tidal. And barrages. This is all in the past. Stuff they’ve either read – in an article in a magazine at the dentist’s surgery waiting room, and they think, alright I’ll use that in a TV programme I’ve been invited to speak on, like Question Time. I think that perhaps, to change the direction of the argument, we might need to rubbish their contribution. A technological society needs to be talking about gasification, catalysis. If you regard yourselves as educated, and have a technological society – your way of living in the future is not only in manufacturing but also ideas – you need to be talking about this not that : low carbon gas fuels, not nuclear power. Ministers and senior civil servants probably suffer from poor briefing – or no briefing. They are relying on what is literally hearsay – informal discussions, or journalists effectively representing industrial interests. Newspapers are full of rubbish and it circulates, like gyres in the oceans. Just circulates around and around – full of rubbish.

    I think part of the problem is that the politicians and chief civil servants and ministers are briefed by the “Old Guard” – very often the ex-nuclear power industry guard. They still believe in big construction projects, with long lead times and massive capital investment, whereas Renewable Electricity is racing ahead, piecemeal, and private investors are desperate to get their money into wind power and solar power because the returns are almost immediate and risk-free.

    Together in Electric Dreams

    Question : Why are the UK Government ploughing on with plans for so much nuclear power ?

    1. They believe that a lot of transport and heat can be made to go electric.
    2. They think they can use spent nuclear fuel in new reactors.
    3. They think it will be cheaper than everything else.
    4. They say it’s vital for UK Energy Security – for emissions reductions, for cost, and for baseload. The big three – always the stated aim of energy policy, and they think nuclear ticks all those three boxes. But it doesn’t.

    What they’ll say is, yes, you have to import uranium, but you’ve got a 4 year stock. Any war you’re going to get yourselves involved in you can probably resolve in 4 days, or 4 weeks. If you go for a very high nuclear scenario, you would be taking quite a big share of the global resource of uranium. There’s 2,600 TWh of nuclear being produced globally. And global final energy demand is around 100,000 TWh – so nuclear power currently produces around 2.6% of global energy supply. At current rates of nuclear generation, according to the World Nuclear Association, you’ve got around 80 years of proven reserves and probably a bit more. Let’s say you double nuclear output by 2050 or 2040 – but in the same time you might just have enough uranium – and then find a bit more. But global energy demand rises significantly as well – so nuclear will still only provide around 3% of global energy demand. That’s not a climate solution – it’s just an energy distraction. All this guff about fusion. Well.

    Cornering The Market In Undug Uranium

    A 75 GW programme would produce at baseload 590 TWh a year – divide by 2,600 – is about 23% of proven global uranium reserves. You’re having to import, regardless of what other countries are doing, you’re trying to corner the market – roughly a quarter. Not even a quarter of the market – a quarter of all known reserves – it’s not all been produced yet. It’s still in the ground. So could you be sure that you could actually run these power stations if you build them ? Without global domination of the New British Empire [...]. The security issues alone – defending coastal targets from a tweeb with a desire to blow them up. 50 years down the line they’re full of radioactive spent fuel that won’t have a repository to go to – we don’t want one here – and how much is it going to cost ?

    My view is that offshore wind will be a major contributor in a high or 100% Renewable Electricity scenario by 2050 or 2060. Maybe 180 GW, that will also be around 600 TWh a year – comparable to that maximum nuclear programme. DECC’s final energy demand 2050 – several scenarios – final energy demand from 6 scenarios came out as between roughly 1,500 TWh a year and the maximum 2,500 TWh. Broadly speaking, if you’re trying to do that just with Renewable Electricity, you begin to struggle quite honestly, unless you’re doing over 600 TWh of offshore wind, and even then you need a fair amount of heat pump stuff which I’m not sure will come through. The good news is that solar might – because of the cost and technology breakthroughs. That brings with it a problem – because you’re delivering a lot of that energy in summer. The other point – David MacKay would say – in his book his estimate was 150 TWh from solar by 2050, on the grounds that that’s where you south-facing roofs are – you need to use higher efficiency triple junction cells with more than 40% efficiency and this would be too expensive for a rollout which would double or triple that 150 TWh – that would be too costly – because those cells are too costly. But with this new stuff, you might get that. Not only the cost goes down, but the coverage goes down. Not doing solar across swathes of countryside. There have always been two issues with solar power – cost and where it’s being deployed.

    Uh-Oh, Summer Days. Uh-Oh, Summer Nights

    With the solar-wind headline, summer days and summer nights are an issue.

    With the nuclear headline, 2040 – they would have up to 50 GW, and that would need to run at somewhere between 75% and 95% capacity – to protect the investment and electric generation turbines.

    It will be interesting to provide some figures – this is how much over-capacity you’re likely to get with this amount of offshore wind. But if you have this amount of nuclear power, you’ll get this amount [...]

    Energy demand is strongly variable with season. We have to consider not just power, but heat – you need to get that energy out in winter – up to 4 times as much during peak in winter evenings. How are you going to do that ? You need gas – or you need extensive Combined Heat and Power (CHP) (which needs gas). Or you need an unimaginable deployment of domestic heat pumps. Air source heat pumps won’t work at the time you need them most. Ground source heat pumps would require the digging up of Britain – and you can’t do that in most urban settings.

    District Heat Fields

    The other way to get heat out to everyone in a low carbon world – apart from low carbon gas – is having a field-based ground source heat pump scheme – just dig up a field next to a city – and just put in pipes and boreholes in a field. You’re not disturbing anybody. You could even grow crops on it next season. Low cost and large scale – but would need a District Heating (DH) network. There are one or two heat pump schemes around the world. Not sure if they are used for cooling in summer or heat extraction in the winter. The other thing is hot water underground. Put in an extra pipe in the normal channels to domestic dwellings. Any excess heat from power generation or electrolysis or whatever is put down this loop and heats the sub-ground. Because heat travels about 1 metre a month in soil, that heat should be retained for winter. A ground source heat sink. Geothermal energy could come through – they’re doing a scheme in Manchester. If there’s a nearby heat district network – it makes it easier. Just want to tee it into the nearest DH system. The urban heat demand is 150 TWh a year. You might be able to put DH out to suburban areas as well. There are 9 million gas-connected suburban homes – another about 150 TWh there as well – or a bit more maybe. Might get to dispose of 300 TWh in heat through DH. The Green Deal insulation gains might not be what is claimed – and condensing gas boiler efficiencies are not that great – which feeds into the argument that in terms of energy efficiency, you not only want to do insulation, but also DH – or low carbon gas. Which is the most cost-effective ? Could argue reasonable energy efficiency measures are cheapest – but DH might be a better bet. That involves a lot of digging.

    Gas Is The Logical Answer

    But everything’s already laid for gas. (…but from the greatest efficiency first perspective, if you’re not doing DH, you’re not using a lot of Renewable Heat you could otherwise use [...] )

    The best package would be the use of low carbon gases and sufficient DH to use Renewable Heat where it is available – such as desalination, electrolysis or other energy plant. It depends where the electrolysis is being done.

    The Age of Your Carbon

    It also depends on which carbon atoms you’re using. If you are recycling carbon from the combustion of fossil fuels into Renewable Gas, that’s OK. But you can’t easily recapture carbon emissions from the built environment (although you could effectively do that with heat storage). You can’t do carbon capture from transport either. So your low carbon gas has to come from biogenic molecules. Your Renewable Gas has to be synthesised using biogenic carbon molecules rather than fossil ones.

    [...] I’m using the phrase “Young Carbon”. Young Carbon doesn’t have to be from plants – biological things that grow.

    Well, there’s Direct Air Capture (DAC). It’s simple. David Sevier, London-based, is working on this. He’s using heat to capture carbon dioxide. You could do it from exhaust in a chimney or a gasification process – or force a load of air through a space. He would use heat and cooling to create an updraft. It would enable the “beyond capture” problem to be circumvented. Cost is non-competitive. Can be done technically. Using reject heat from power stations for the energy to do it. People don’t realise you can use a lot of heat to capture carbon, not electricity.

    Young Carbon from Seawater

    If you’re playing around with large amounts of seawater anyway – that is, for desalination for irrigation, why not also do Renewable Hydrogen, and pluck the Carbon Dioxide out of there too to react with the Renewable Hydrogen to make Renewable Methane ? I’m talking about very large amounts of seawater. Not “Seawater Greenhouses” – condensation designs mainly for growing exotic food. If you want large amounts of desalinated water – and you’re using Concentrated Solar Power – for irrigating deserts – you would want to grow things like cacti for biological carbon.

    Say you had 40 GW of wind power on Dogger Bank, spinning at 40% load factor a year. You’ve also got electrolysers there. Any time you’re not powering the grid, you’re making gas – so capturing carbon dioxide from seawater, splitting water for hydrogen, making methane gas. Wouldn’t you want to use flash desalination first to get cleaner water for electrolysis ? Straight seawater electrolysis is also being done.

    It depends on the relative quantities of gas concentrated in the seawater. If you’ve got oxygen, hydrogen and carbon dioxide, that would be nice. You might get loads of oxygen and hydrogen, and only poor quantities of carbon dioxide ?

    But if you could get hydrogen production going from spare wind power. And even if you had to pipe the carbon dioxide from conventional thermal power plants, you’re starting to look at a sea-based solution for gas production. Using seawater, though, chlorine is the problem [...]

    Look at the relative density of molecules – that sort of calculation that will show if this is going to fly. Carbon dioxide is a very fixed, stable molecule – it’s at about the bottom of the energy potential well – you have to get that reaction energy from somewhere.

    How Much Spare Power Will There Be ?

    If you’ve got an offshore wind and solar system. At night, obviously, the solar’s not working (unless new cells are built that can run on infrared night-time Earthshine). But you could still have 100 GWh of wind power at night not used for the power grid. The anticipated new nuclear 40 GW nuclear by 2030 will produce about 140 GWh – this would just complicate problems – adding baseload nuclear to a renewables-inclusive scenario. 40 GW is arguably a reasonable deployment of wind power by 2030 – low if anything.

    You get less wind in a nuclear-inclusive scenario, but the upshot is you’ve definitely got a lot of power to deal with on a summer night with nuclear power. You do have with Renewable Electricity as well, but it varies more. Whichever route we take we’re likely to end up with excess electricity generation on summer nights.

    In a 70 GW wind power deployment (50 GW offshore, 20 GW onshore – 160 TWh a year), you might have something like 50 to 100 GWh per night of excess (might get up to 150 GWh to store on a windy night). But if you have a 16 GW nuclear deployment by 2030 (125 TWh a year), you are definitely going to have 140 GWh of excess per night (that’s 16 GW for 10 hours less a bit). Night time by the way is roughly between 9pm and 7am between peak demands.

    We could be making a lot of Renewable Gas !

    Can you build enough Renewable Gas or whatever to soak up this excess nuclear or wind power ?

    The energy mix is likely to be in reality somewhere in between these two extremes of high nuclear or high wind.

    But if you develop a lot of solar – so that it knocks out nuclear power – it will be the summer day excess that’s most significant. And that’s what Germany is experiencing now.

    Choices, choices, choices

    There is a big choice in fossil fuels which isn’t really talked about very often – whether the oil and gas industry should go for unconventional fossil fuels, or attempt to make use of the remaining conventional resources that have a lower quality. The unconventionals narrative – shale gas, coalbed methane, methane hydrates, deepwater gas, Arctic oil and gas, heavy oil, is running out of steam as it becomes clear that some of these choices are expensive, and environmentally damaging (besides their climate change impact). So the option will be making use of gas with high acid gas composition. And the technological solutions for this will be the same as needed to start major production of Renewable Gas.

    Capacity Payments

    But you still need to answer the balancing question. If you have a high nuclear power scenario, you need maybe 50 TWh a year of gas-fired power generation. If high Renewable Electricity, you will need something like 100 TWh of gas, so you need Carbon Capture and Storage – or low carbon gas.

    Even then, the gas power plants could be running only 30% of the year, and so you will need capacity payments to make sure new flexible plants get built and stay available for use.

    If you have a high nuclear scenario, coupled with gas, you can meet the carbon budget – but it will squeeze out Renewable Electricity. If high in renewables, you need Carbon Capture and Storage (CCS) or Carbon Capture and Recycling into Renewable Gas, but this would rule out nuclear power. It depends which sector joins up with which.

    Carbon Capture, Carbon Budget

    Can the Drax power plant – with maybe one pipeline 24 inches in diameter, carrying away 20 megatonnes of carbon dioxide per year – can it meet the UK’s Carbon Budget target ?

  • Wind Powers Electricity Security

    Posted on August 17th, 2013 Jo No comments




    Have the anti-wind power lobby struck again ? A seemingly turbulent researcher from Private Eye magazine rang me on Thursday evening to ask me to revise my interpretation of his “Keeping The Lights On” piece of a few weeks previously. His article seemed at first glance to be quite derogatory regarding the contribution of wind power to the UK’s electricity supply. If I were to look again, I would find out, he was sure, that I was wrong, and he was right.

    So I have been re-reviewing the annual 2013 “Electricity Capacity Assessment Report” prepared by Ofgem, the UK Government’s Office of Gas and Electricity Markets, an independent National Regulatory Authority. I have tried to be as fair-minded and generous as possible to “Old Sparky” at Private Eye magazine, but a close re-reading of the Ofgem report suggests he is apparently mistaken – wind power is a boon, not a burden (as he seems to claim).

    In the overview to the Ofgem report, they state, “our assessment suggests that the risks to electricity security of supply over the next six winters have increased since our last report in October 2012. This is due in particular to deterioration in the supply-side outlook. There is also uncertainty over projected reductions in demand.” Neither of these issues can be associated with wind power, which is being deployed at an accelerating rate and so is providing increasing amounts of electricity.

    The report considers risks to security of the electricity supply, not an evaluation of the actual amounts of power that will be supplied. How are these risks to the security of supply quantified ? There are several metrics provided from Ofgem’s modelling, including :-

    a. LOLE – Loss of Load Expectation – the average number of hours per year in which electricity supply does not meet electricity demand (if the grid System Operator does not take steps to balance it out).

    (Note that Ofgem’s definition of LOLE is difference from other people’s “LOLE is often interpreted in the academic literature as representing the probability of disconnections after all mitigation actions available to the System Operator have been exhausted. We consider that a well functioning market should avoid using mitigation actions in [sic] regular basis and as such we interpret LOLE as the probability of having to implement mitigation actions.”)

    b. EEU – Expected Energy Unserved (or “Un-served”) – the average amount of electricity demand that is not met in a year – a metric that combines both the likelihood and the size of any shortfall.

    c. Frequency and Duration of Expected Outages – a measure of the risk that an electricity consumer faces of controlled disconnection because supply does not meet demand.

    The first important thing to note is that the lights are very unlikely to go out. The highest value of LOLE, measured in hours per year is under 20. That’s 20 hours each year. Not 20 days. And this is not anticipated to be 20 days in a row, either. Section 1.11 says “LOLE, as interpreted in this report, is not a measure of the expected number of hours per year in which customers may be disconnected. For a given level of LOLE and EEU, results may come from a large number of small events where demand exceeds supply in principle but that can be managed by National Grid through a set of mitigation actions available to them as System Operator. [...] Given the characteristics of the GB system, any shortfall is more likely to take the form of a large number of small events that would not have a direct impact on customers.”

    Section 2.19 states, “The probabilistic measures of security of supply presented in this report are often misinterpreted. LOLE is the expected number of hours per year in which supply does not meet demand. This does not however mean that customers will be disconnected or that there will be blackouts for that number of hours a year. Most of the time, when available supply is not high enough to meet demand, National Grid may implement mitigation actions to solve the problem without disconnecting any customers. However, the system should be planned to avoid the use of mitigation actions and that is why we measure LOLE ahead of any mitigation actions being used”. And Section 2.20, “LOLE does not necessarily mean disconnections but they do remain a possibility. If the difference between available supply and demand is so large that the mitigation actions are not enough to meet demand then some customers have to be disconnected – this is the controlled disconnections step in Figure 14 above. In this case the [System Operator] SO will disconnect industrial demand before household demand.”

    And in Section 2.21. “The model output numbers presented here refer to a loss of load of any kind. This could be the sum of several small events (controlled through mitigation actions) or a single large event. As a consequence of the mitigation actions available, the total period of disconnections for a customer will be lower than the value of LOLE.”

    The report does anticipate that there are risks of large events where the lights could go out, even if only very briefly, for non-emergency customers : “The results may also come from a small number of large events (eg the supply deficit is more than 2 – 3 gigawatts (GW)) where controlled disconnections cannot be avoided.” But in this kind of scenario two very important things would happen. Those with electricity contracts with a clause permitting forced disconnection would lose power. And immediate backup power generation would be called upon to bridge the gap. There are many kinds of electricity generation that can be called on to start up in a supply crisis – some of them becoming operational in minutes, and others in hours.

    As the report says in Section 2.24 “Each [Distribution Network Operator] DNO ensures it can provide a 20% reduction of its total system demand in four incremental stages (between 4% and 6%), which can be achieved at all times, with or without prior warning, and within 5 minutes of receipt of an instruction from the System Operator. The reduction of a further 20% (40% in total) can be achieved following issue of the appropriate GB System Warning by National Grid within agreed timescales”.

    It’s all about the need for National Grid to balance the system. Section 2.9 says, “LOLE is not a measure of the expected number of hours per year in which customers may be disconnected. We define LOLE to indicate the number of hours in which the system may need to respond to tight conditions.”

    The report also rules some potential sources of disruption of supply outside the remit of this particular analysis – see Section 3.17 “There are other reasons why electricity consumers might experience disruptions to supply, which are out of the scope of this assessment and thus not captured by this model, such as: Flexibility : The ability of generators to ramp up in response to rapid increases in demand or decreases in the output of other generators; Insufficient reserve : Unexpected increases in demand or decreases in available capacity in real time which must be managed by the System Operator through procurement and use of reserve capacity; Network outages : Failures on the electricity transmission or distribution networks; Fuel availability : The availability of the fuel used by generators. In particular the security of supplies of natural gas at times of peak electricity demand.”

    Crucially, the report says there is much uncertainty in their modelling of LOLE and EEU. In Section 2.26, “The LOLE and EEU estimates are just an indication of risk. There is considerable uncertainty around the main variables in the calculation (eg demand, the behaviour of interconnectors etc.)”

    (Note : interconnectors are electricity supply cables that join the UK to other countries such as Ireland and Holland).

    Part of the reason for Ofgem’s caveat of uncertainty is the lack of appropriate data. Although they believe they have better modelling of wind power since their 2012 report (see Sections 3.39 to 3.50), there are data sets they believe should be improved. For example, data on Demand Side Response (DSR) – the ability of the National Grid and its larger or aggregated consumers to alter levels of demand on cue (see Sections 4.7 to 4.10 of the document detailing decisions about the methodology). A lack of data has led to certain assumptions being retained, for example, the assumption that there is no relationship between available wind power and periods of high demand – in the winter season (see Section 2.5 and Sections 4.11 to 4.17 of the methodology decisions document).

    In addition to these uncertainties, the sensitivity cases used in the modelling are known to not accurately reflect the capability of management of the power grid. In the Executive Summary on page 4, the report says, “These sensitivities only illustrate changes in one variable at a time and so do not capture potential mitigating effects, for example of the supply side reacting to higher demand projections.” And in Section 2.16 it says, “Each sensitivity assumes a change in one variable from the Reference Scenario, with all other assumptions being held constant. The purpose of this is to assess the impact of the uncertainty related to each variable in isolation, on the risk measures. Our report is not using scenarios (ie a combination of changes in several variables to reflect alternative worlds or different futures), as this would not allow us to isolate the impact of each variable on the risk measures.”

    Thus, the numbers that are output by the modelling are perforce illustrative, not definitive.

    What “Old Sparky” at Private Eye was rattled by in his recent piece was the calculation of Equivalent Firm Capacity (EFC) in the Ofgem report.

    On page 87, Section 3.55, the Ofgem report defines the “standard measure” EFC as “the amount of capacity that is required to replace the wind capacity to achieve the same level of LOLE”, meaning the amount of always-on generation capacity required to replace the wind capacity to achieve the same level of LOLE. Putting it another way on page 33, in the footnotes for Section 3.29, the report states, “The EFC is the quantity of firm capacity (ie always available) that can be replaced by a certain volume of wind generation to give the same level of security of supply, as measured by LOLE.”

    Wind power is different from fossil fuel-powered generation as there is a lot of variability in output. Section 1.48 of the report says, “Wind generation capacity is analysed separately given that its outcome in terms of generation availability is much more variable and difficult to predict.” Several of the indicators calculated for the report are connected with the impact of wind on security of the power supply. However, variation in wind power is not the underlying reason for the necessity of this report. Other electricity generation plant has variation in output leading to questions of security of supply. In addition, besides planned plant closures and openings, there are as-yet-unknown factors that could impact overall generation capacity. Section 2.2 reads, “We use a probabilistic approach to assess the uncertainty related to short-term variations in demand and available conventional generation due to outages and wind generation. This is combined with sensitivity analysis to assess the uncertainty related to the evolution of electricity demand and supply due to investment and retirement decisions (ie mothballing, closures) and interconnector flows, among others.”

    The report examines the possibility that wind power availability could be correlated to winter season peak demand, based on limited available data, and models a “Wind Generation Availability” sensitivity (see Section 3.94 to Section 3.98, especially Figure 64). In Section 3.42 the report says, “For the wind generation availability sensitivity we assume that wind availability decreases at time of high demand. In particular this sensitivity assumes a reduction in the available wind resource for demand levels higher than 92% of the ACS peak demand. The maximum reduction is assumed to be 50% for demand levels higher than 102% of ACS peak demand.” Bear in mind that this is only an assumption.

    In Appendix 5 “Detailed results tables”, Table 34, Table 35 and Table 37 show how this modelling impacts the calculation of the indicative Equivalent Firm Capacity (EFC) of wind power.

    In the 2018/2019 timeframe, when there is expected to be a combined wind power capacity of 8405 megawatts (MW) onshore plus 11705 MW offshore = 20110 MW, the EFC for wind power is calculated to be 2546 MW in the “Wind Generation Availability” sensitivity line, which works out at 12.66% of the nameplate capacity of the wind power. Note : 100 divided by 12.66 is 7.88, or a factor of roughly 8.

    At the earlier 2013/2014 timeframe, when combined wind power capacity is expected to be 3970 + 6235 MW = 10205 MW, and the EFC is at 1624 MW or 15.91% for the “Wind Generation Sensitivity” line. Note : 100 divided by 15.91 = 6.285, or a factor of roughly 6.

    “Old Sparky” is referring to these factor figures when he says in his piece (see below) :-

    “[...] For every one megawatt of reliable capacity (eg a coal-fired power
    station) that gets closed, Ofgem calculates Britain would need six to
    eight
    megawatts of windfarm capacity to achieve the original level of
    reliability – and the multiple is rising all the time. Windfarms are
    not of course being built at eight times the rate coal plants are
    closing – hence the ever-increasing likelihood of blackouts. [...]”

    Yet he has ignored several caveats given in the report that place these factors in doubt. For example, the sensitivity analysis only varies one factor at a time and does not attempt to model correlated changes in other variables. He has also omitted to consider the relative impacts of change.

    If he were to contrast his statement with the “Conventional Low Generation Availability” sensitivity line, where wind power EFC in the 2013/2014 timeframe is calculated as a healthy 26.59% or a factor of roughly 4; or 2018/2019 when wind EFC is 19.80% or a factor of roughly 5.

    Note : The “Conventional Low Generation Availability” sensitivity is drawn from historical conventional generation operating data, as outlined in Sections 3.31 to 3.38. Section 3.36 states, “The Reference Scenario availability is defined as the mean availability of the seven winter estimates. The availability values used for the low (high) availability sensitivities are defined as the mean minus (plus) one standard deviation of the seven winter estimates.”

    Table 30 and Table 31 show that low conventional generation availability will probably be the largest contribution to energy security uncertainty in the critical 2015/2016 timeframe.

    The upshot of all of this modelling is that wind power is actually off the hook. Unforeseen alterations in conventional generation capacity are likely to have the largest impact. As the report says in Section 4.21 “The figures indicate that reasonably small changes in conventional generation availability have a material impact on the risk of supply shortfalls. This is most notable in 2015/16, where the estimated LOLE ranges from 0.2 hours per year in the high availability sensitivity to 16 hours per year in the low availability sensitivity, for the Reference Scenario is 2.9 hours per year.”

    However, Section 1.19 is careful to remind us, “Wind generation, onshore and offshore, is expected to grow rapidly in the period of analysis and especially after 2015/16, rising from around 9GW of installed capacity now to more than 20GW by 2018/19. Given the variability of wind speeds, we estimate that only 17% of this capacity can be counted as firm (ie always available) for security of supply purposes by 2018/19.” This is in the Reference Scenario.

    The sensitivities modelled in the report are a measure of risk, and do not provide absolute values for any of the output metrics, especially since the calculations are dependent on so many factors, including economic stimulus for the building of new generation plant.

    Importantly, recent decisions by gas-fired power plant operators to “mothball”, or close down their generation capacity, are inevitably going to matter more than how much exactly we can rely on wind power.

    Many commentators neglect to make the obvious point that wind power is not being used to replace conventional generation entirely, but to save fossil fuel by reducing the number of hours conventional generators have to run. This is contributing to energy security, by reducing the cost of fossil fuel that needs to be imported. However, the knock-on effect is this is having an impact on the economic viability of these plant because they are not always in use, and so the UK Government is putting in place the “Capacity Mechanism” to make sure that mothballed plant can be put back into use when required, during those becalmed, winter afternoons when power demand is at its peak.

    “Keeping the Lights On”
    page 14
    by “Old Sparky”

    The report from energy regulator Ofgem that sparked headlines on
    potential power cuts contains much new analysis highlighting the
    uselessness of wind generation in contributing to security of
    electricity supply, aka the problem of windfarm “intermittency”. But
    the problem is being studiously ignored by the Department of Energy
    and Climate Change (DECC).

    As coal power stations shut down, windfarms are notionally replacing
    them. If, say, only one windfarm were serving the grid, its inherent
    unreliability could easily be compensated for. But if there were
    [italics] only windfarms, and no reliable sources of electricity
    available at all, security of supply would be hugely at risk. Thus the
    more windfarms there are, the less they contribute to security.

    For every one megawatt of reliable capacity (eg a coal-fired power
    station) that gets closed, Ofgem calculates Britain would need six to
    eight megawatts of windfarm capacity to achieve the original level of
    reliability – and the multiple is rising all the time. Windfarms are
    not of course being built at eight times the rate coal plants are
    closing – hence the ever-increasing likelihood of blackouts.

    [...]

    In consequence windfarms are being featherbedded – not only with
    lavish subsidies, but also by not being billed for the ever-increasing
    trouble they cause. When the DECC was still operating Plan B, aka the
    dash for gas ([Private] Eye [Issue] 1266), the cost of intermittency
    was defined in terms of balancing the grid by using relatively clean
    and cheap natural gas. Now that the department has been forced to
    adopt emergency Plan C ([Private] Eye [Issue] 1344), backup for
    intermittent windfarm output will increasingly be provided by dirty,
    expensive diesel generators.

    “Keeping the Lights On”

    As pandemonium breaks out in newspapers at the prospect of electricity
    blackouts, emergency measures are being cobbled together to ensure the
    lights stay on. They will probably succeed – but at a cost.

    Three years ago incoming coalition ministers were briefed that when
    energy policy Plan A (windfarms, new nukes and pixie-dust) failed, Plan B
    would be in place – a new dash for gas ([Private] Eye [Issue] 1266).

    Civil servants then devised complex “energy market reforms” (EMR) to make
    this happen. It is now clear that these, too, have failed. Coal-fired power
    stations are closing quicker than new gas plants are being built. As energy
    regulator Ofgem put it bluntly last week: “The EMR aims to incentivise
    industry to address security of supply in the medium term, but is not able
    to bring forward investment in new capacity in time.”

    Practical people in the National Grid are now hatching emergency Plan C.
    They will pay large electricity users to switch off when requested;
    encourage industrial companies and even hospitals to generate their own
    diesel-fired electricity (not a hard sell when the grid can’t be relied
    on); hire diesel generators to make up for the intermittency of windfarms
    ([Private] Eye [Issue] 1322); and bribe electricity companies to bring
    mothballed gas-fired plants back into service.

    Some of these steps are based on techniques previously used in extreme
    circumstances, and will probably keep most of the lights on. But this
    should not obscure the fact that planning routine use of emergency
    measures is an indictment of energy policy. And since diesel is much
    more expensive and polluting than gas, electricity prices and CO2
    emissions will be higher than if Plan B had worked.

  • James Delingpole : Worsely Wronger

    Posted on July 15th, 2013 Jo 4 comments

    I wonder to myself – how wrong can James Delingpole get ? He, and Christopher Booker and Richard North, have recently attempted to describe something very, very simple in the National Grid’s plans to keep the lights on. And have failed, in my view. Utterly. In my humble opinion, it’s a crying shame that they appear to influence others.

    “Dellingpole” (sic) in the Daily Mail, claims that the STOR – the Short Term Operating Reserve (not “Operational” as “Dellingpole” writes) is “secret”, for “that significant period when the wind turbines are not working”, and that “benefits of the supposedly ‘clean’ energy produced by wind turbines are likely to be more than offset by the dirty and inefficient energy produced by their essential diesel back-up”, all of which are outrageously deliberate misinterpretations of the facts :-

    http://www.dailymail.co.uk/news/article-2362762/The-dirty-secret-Britains-power-madness-Polluting-diesel-generators-built-secret-foreign-companies-kick-theres-wind-turbines–insane-true-eco-scandals.html
    “The dirty secret of Britain’s power madness: Polluting diesel generators built in secret by foreign companies to kick in when there’s no wind for turbines – and other insane but true eco-scandals : By James Dellingpole : PUBLISHED: 00:27, 14 July 2013″

    If “Dellingpole” and his compadre in what appear to be slurs, Richard North, were to ever do any proper research into the workings of the National Grid, they would easily uncover that the STOR is a very much transparent, publicly-declared utility :-

    http://www.nationalgrid.com/uk/Electricity/Balancing/services/balanceserv/reserve_serv/stor/

    STOR is not news. Neither is the need for it to be beefed up. The National Grid will lose a number of electricity generation facilities over the next few years, and because of the general state of the economy (and resistance to wind power and solar power from unhelpful folk like “Dellingpole”) investment in true renewables will not entirely cover this shortfall.

    Renewable energy is intermittent and variable. If an anticyclone high pressure weather system sits over Britain, there could be little wind. And if the sky is cloudy, there could be much less sun than normal. More renewable power feeding the grid means more opportunities when these breaks in service amount to something serious.

    Plus, the age of other electricity generation plants means that the risk of “unplanned outage”, from a nuclear reactor, say, is getting higher. There is a higher probability of sudden step changes in power available from any generator.

    The gap between maximum power demand and guaranteed maximum power generation is narrowing. In addition, the threat of sudden changes in output supply is increasing.

    With more generation being directly dependent on weather conditions and the time of day, and with fears about the reliability of ageing infrastructure, there is a need for more very short term immediate generation backup to take up the slack. This is where STOR comes in.

    Why does STOR need to exist ? The answer’s in the name – for short term balancing issues in the grid. Diesel generation is certainly not intended for use for long periods. Because of air quality issues. Because of climate change issues. Because of cost.

    If the Meteorological Office were to forecast a period of low wind and low incident solar radiation, or a nuclear reactor started to dip in power output, then the National Grid could take an old gas plant (or even an old coal plant) out of mothballs, pull off the dust sheets and crank it into action for a couple of days. That wouldn’t happen very often, and there would be time to notify and react.

    But if a windfarm suddenly went into the doldrums, or a nuclear reactor had to do an emergency shutdown, there would be few power stations on standby that could respond immediately, because it takes a lot of money to keep a power plant “spinning”, ready to use at a moment’s notice.

    So, Delingpole, there’s no conspiracy. There’s engagement with generators to set up a “first responder” network of extra generation capacity for the grid. This is an entirely public process. It’s intended for short bursts of immediately-required power because you can’t seem to turn your air conditioner off. The cost and emissions will be kept to a minimum. You’re wrong. You’re just full of a lot of hot air.

  • A Report from Tasmania

    Posted on February 4th, 2013 Jo 1 comment

    During the worst of the austral summer in Tasmania at the start of 2013, an Austrian friend of mine was travelling through the region, and sent back the following report.


    “We arrived in Tassie [Tasmania] on the 6th of January 2013. When I looked outside the window of the plane I saw many burning fields and a lot of black smoke was in the air.”

    “We picked up our luggage and went to the car rental counter. Actually we were lucky to catch the last rental car, as most of the cars were stuck in the Peninsula at Port Arthur and people couldn’t drive them back as all roads were blocked already.

    There were over 40 bush-fires in the area and most of the people have been evacuated either by sailboats and ships, as the whole island (Peninsula) Dunally was on fire.

    We drove directly up to the northern part of Tasmania away from the bush-fires.

    On the radio we heard many additional fire-warnings and had to take another highway in order to reach the Cradle Mountain National Park.

    The air was filled with smoke and the smell was terrible. As we arrived in the National Park all of a sudden it started to rain and didn’t stop for the rest of the day. The next day also…rain, rain, rain.

    250km south of Tassie bush-fires and here we are and felt like we were swept away by the strong winds and rainfalls in the middle of Tassie. :) It has been also really cold. Strange feeling to experience such a different weather-condition within only one day.”

  • A Referendum for Energy

    Posted on January 24th, 2013 Jo No comments

    As I dodged the perfunctory little spots of snow yesterday, on my way down to Highbury and Islington underground train station, I passed a man who appeared to have jerky muscle control attempting to punch numbers on the keypad of a cash machine in the wall. He was missing, but he was grinning. A personal joke, perhaps. The only way he could get his money out of the bank to buy a pint of milk and a sliced loaf for his tea was to accurately tap his PIN number. But he wasn’t certain his body would let him. I threw him an enquiring glance, but he seemed too involved in trying to get control of his arms and legs to think of accepting help.

    This, I felt, was a metaphor for the state of energy policy and planning in the United Kingdom – everybody in the industry and public sector has focus, but nobody appears to have much in the way of overall control – or even, sometimes, direction. I attended two meetings today setting out to address very different parts of the energy agenda : the social provision of energy services to the fuel-poor, and the impact that administrative devolution may have on reaching Britain’s Renewable Energy targets.

    At St Luke’s Centre in Central Street in Islington, I heard from the SHINE team on the progress they are making in providing integrated social interventions to improve the quality of life for those who suffer fuel poverty in winter, where they need to spend more than 10% of their income on energy, and are vulnerable to extreme temperatures in both summer heatwaves and winter cold snaps. The Seasonal Health Interventions Network was winning a Community Footprint award from the National Energy Action charity for success in their ability to reach at-risk people through referrals for a basket of social needs, including fuel poverty. It was pointed out that people who struggle to pay energy bills are more likely to suffer a range of poverty problems, and that by linking up the social services and other agencies, one referral could lead to multiple problem-solving.

    In an economy that is suffering signs of contraction, and with austerity measures being imposed, and increasing unemployment, it is clear that social services are being stretched, and yet need is still great, and statutory responsibility for handling poverty is still mostly a publicly-funded matter. By offering a “one-stop shop”, SHINE is able to offer people a range of energy conservation and efficiency services alongside fire safety and benefits checks and other help to make sure those in need are protected at home and get what they are entitled to. With 1 in 5 households meeting the fuel poverty criteria, there is clearly a lot of work to do. Hackney and Islington feel that the SHINE model could be useful to other London Boroughs, particularly as the Local Authority borders are porous.

    We had a presentation on the Cold Weather Plan from Carl Petrokovsky working for the Department of Health, explaining how national action on cold weather planning is being organised, using Met Office weather forecasts to generate appropriate alert levels, in a similar way to heatwave alerts in summer – warnings that I understand could become much more important in future owing to the possible range of outcomes from climate change.

    By way of some explanation – more global warming could mean significant warming for the UK. More UK warming could mean longer and, or, more frequent heated periods in summer weather, perhaps with higher temperatures. More UK warming could also mean more disturbances in an effect known as “blocking” where weather systems lock into place, in any season, potentially pinning the UK under a very hot or very cold mass of air for weeks on end. In addition, more UK warming could mean more precipitation – which would mean more rain in summer and more snow in winter.

    Essentially, extremes in weather are public health issues, and particularly in winter, more people are likely to suffer hospitalisation from the extreme cold, or falls, or poor air quality from boiler fumes – and maybe end up in residential care. Much of this expensive change of life is preventable, as are many of the excess winter deaths due to cold. The risks of increasing severity in adverse conditions due to climate change are appropriately dealt with by addressing the waste of energy at home – targeting social goals can in effect contribute to meeting wider adaptational goals in overall energy consumption.

    If the UK were to be treated as a single system, and the exports and imports of the most significant value analysed, the increasing net import of energy – the yawning gap in the balance of trade – would be seen in its true light – the country is becoming impoverished. Domestic, indigenously produced sources of energy urgently need to be developed. Policy instruments and measured designed to reinvigorate oil and gas exploration in the North Sea and over the whole UKCS – UK Continental Shelf – are not showing signs of improving production significantly. European-level policy on biofuels did not revolutionise European agriculture as regards energy cropping – although it did contribute to decimating Indonesian and Malaysian rainforest. The obvious logical end point of this kind of thought process is that we need vast amounts of new Renewable Energy to retain a functioning economy, given global financial, and therefore, trade capacity, weakness.

    Many groups, both with the remit for public service and private enterprise oppose the deployment of wind and solar power, and even energy conservation measures such as building wall cladding. Commentators with access to major media platforms spread disinformation about the ability of Renewable Energy technologies to add value. In England, in particular, debates rage, and many hurdles are encountered. Yet within the United Kingdom as a whole, there are real indicators of progressive change, particularly in Scotland and Wales.

    I picked up the threads of some of these advances by attending a PRASEG meeting on “Delivering Renewable Energy Under Devolution”, held at the Institution of Mechanical Engineers in Westminster, London; a tour to back up the launch of a new academic report that analyses performance of the devolved administrations and their counterpart in the English Government in Westminster. The conclusions pointed to something that I think could be very useful – if Scotland takes the referendum decision for independence, and continues to show strong leadership and business and community engagement in Renewable Energy deployment, the original UK Renewable Energy targets could be surpassed.

    I ended the afternoon exchanging some perceptions with an academic from Northern Ireland. We shared that Eire and Northern Ireland could become virtually energy-independent – what with the Renewable Electricity it is possible to generate on the West Coast, and the Renewable Gas it is possible to produce from the island’s grass (amongst other things). We also discussed the tendency of England to suck energy out of its neighbour territories. I suggested that England had appropriated Scottish hydrocarbon resources, literally draining the Scottish North Sea dry of fossil fuels in exchange for token payments to the Western Isles, and suchlike. If Scotland leads on Renewable Energy and becomes independent, I suggested, the country could finally make back the wealth it lost to England. We also shared our views about the Republic of Ireland and Northern Ireland being asked to wire all their new Renewable Electricity to England, an announcement that has been waiting to happen for some time. England could also bleed Wales of green power with the same lines being installed to import green juice from across the Irish Sea.

    I doubt that politics will completely nix progress on Renewable Energy deployment – the economics are rapidly becoming clear that clean, green power and gas are essential for the future. However, I would suggest we could expect some turbulence in the political sphere, as the English have to learn the hard way that they have a responsibility to rapidly increase their production of low carbon energy.

    Asking the English if they want to break ties with the European Union, as David Cameron has suggested with this week’s news on a Referendum, is the most unworkable idea, I think. England, and in fact, all the individual countries of the United Kingdom, need close participation in Europe, to join in with the development of new European energy networks, in order to overcome the risks of economic collapse. It may happen that Scotland, and perhaps Wales, even, separate themselves from any increasing English isolation and join the great pan-Europe energy projects in their own right. Their economies may stabilise and improve, while the fortunes of England may tumble, as those with decision-making powers, crony influence and web logs in the Daily Telegraph and Daily Mail, resist the net benefits of the low carbon energy revolution.

    [ Many thanks to Simon and all at the Unity Kitchen at St Luke's Centre, and the handsomely reviving Unity Latte, and a big hi to all the lunching ladies and gents with whom I shared opinions on the chunkiness of the soup of the day and the correct identification of the vegetables in it. ]

    Other Snapshots of Yesterday #1 : Approached by short woman with a notebook in Parliament Square, pointing out to me a handwritten list that included the line “Big Ben”. I pointed at the clock tower and started to explain. The titchy tourist apologised for non-comprehension by saying, “French”, so then I explained the feature attraction to her in French, which I think quite surprised her. We are all European.

    Other Snapshots of Yesterday #2 : Spoke with an Austrian academic by the fire for coffee at IMechE, One Birdcage Walk, about the odd attitudes as regards gun ownership in the United States, and the American tendency to collective, cohort behaviour. I suggested that this tendency could be useful, as the levels of progressive political thinking, for instance about drone warfare, could put an end to the practice. When aerial bombardment was first conducted, it should have been challenged in law at that point. We are all Europeans.

    Other Snapshots of Yesterday #3 : Met a very creative Belgian from Gent, living in London. We are all European.

    Other Snapshots of Yesterday #4 : We Europeans, we are all so civilised. We think that we need to heat venues for meetings, so that people feel comfortable. Levels of comfort are different for different people, but the lack of informed agreement means that the default setting for temperature always ends up being too high. The St Luke’s Centre meeting room was at roughly 23.5 degrees C when I arrived, and roughly 25 degrees C with all the visitors in the room. I shared with a co-attendee that my personal maximum operating temperature is around 19 degrees C. She thought that was fine for night-time. The IMechE venue on the 2nd floor was roughly 19 – 20 degrees C, but the basement was roughly 24 degrees C. Since one degree Celsius of temperature reduction can knock about 10% of the winter heating bill, why are public meetings about energy not more conscious of adjusting their surroundings ?

  • Boris’ Entirely Accurate Assessment

    Posted on January 21st, 2013 Jo 3 comments

    Image Credit : jgspics

    It’s lucky for Londoners that we have a Mayor of the intellectual stature of Boris Johnson. Not only is he a fashion icon, a promotor of safe cycling, and a total sex god, especially dangling from high wires at Olympic Stadia wearing a rumpled suit, but he’s also a sheer genius on science. He’s as learned as the best taxi chauffeur in the City’s Square Mile, and not only that, he’s studied Earth Sciences in depth, and has so much wisdom from his knowledge, that he feels justified in challenging an entire pantheon of climatologists.

    Here he is writing philanthropically, no doubt, for our general edification, in the Daily Telegraph online,

    “…I am sitting here staring through the window at the flowerpot and the bashed-up barbecue, and I am starting to think this series of winters is not a coincidence. The snow on the flowerpot, since I have been staring, has got about an inch thicker. The barbecue is all but invisible. By my calculations, this is now the fifth year in a row that we have had an unusual amount of snow; and by unusual I mean snow of a kind that I don’t remember from my childhood: snow that comes one day, and then sticks around for a couple of days, followed by more. I remember snow that used to come and settle for just long enough for a single decent snowball fight before turning to slush; I don’t remember winters like this. Two days ago I was cycling through Trafalgar Square and saw icicles on the traffic lights; and though I am sure plenty of readers will say I am just unobservant, I don’t think I have seen that before. I am all for theories about climate change, and would not for a moment dispute the wisdom or good intentions of the vast majority of scientists. But I am also an empiricist; and I observe that something appears to be up with our winter weather, and to call it “warming” is obviously to strain the language…”

    I must defer to the man – his memory is incredibly accurate, and the conclusions based on his impressions entirely valid. It cannot be true that in the winter of 1967-1968, for example, when he was a little brat, that snow was so deep and so treacherous in parts of London that cars could not drive up slopes steeper than about 25 degrees; and that the snow lasted for several weeks and caused major infrastructure disruption, especially when there was a second phase of snowfall. It cannot be true that winters in the UK in the late 1970s and early 1980s were really quite bad, because Boris cannot recall them, despite being nearly aged 50, unless of course, he grew up in another, more tropical part of the world.

    As his claim to be an “empiricist” is backed up by his winter recollections, we can trust what he says about Piers Corbyn, obviously. Piers Corbyn, alone among his generation, perhaps, is reported by BoJo to believe that “global temperature depends not on concentrations of CO2 but on the mood of our celestial orb.” And he has a fascinating, entirely convincing explanation for recent hard winters, “When the Sun has plenty of sunspots, he bathes the Earth in abundant rays. When the solar acne diminishes, it seems that the Earth gets colder. No one contests that when the planet palpably cooled from 1645 to 1715 – the Maunder minimum, which saw the freezing of the Thames – there was a diminution of solar activity. The same point is made about the so-called Dalton minimum, from 1790 to 1830. And it is the view of Piers Corbyn that we are now seeing exactly the same phenomenon today.”

    It’s all so simple, really, and we have to thank Piers Corbyn, shake his hand warmly, and thump him on the back to express our deep gratitude for explaining that history is repeating itself, all over again. Nothing, of course, has changed in the Earth’s atmosphere, so its composition couldn’t be accentuating the Greenhouse Effect, whereby minute amounts of Greenhouse Gases keep the surface of the planet above the 18 or 19 degrees Celsius below freezing point it would be otherwise.

    So of course, just as he is right about solar activity being the primary driver of global temperatures today, just as it was clearly the only significant driver in the past, Piers Corbyn must be entirely correct about his predictions of future cooling, especially because he’s being quoted by Borish Johnson, on the website of a very well-read newspaper, no less, “We are in for a prolonged cold period. Indeed, we could have 30 years of general cooling.”

    The Daily Telegraph have hit on a superb way of guaranteeing web hits. The strategy of setting a cool cat amongst the warming pigeons is even acknowledged by Mr Johnson himself, “all those scientists and environmentalists who will go wild with indignation on the publication of this article”.

    But it appears that despite this clownish, jokey, provocative stance, Boris might actually believe there is something in Piers Corbyn’s analysis : “I am speaking only as a layman [a "layman" with a platform in a national newspaper, which pay him to write this stuff] who observes that there is plenty of snow in our winters these days, and who wonders whether it might be time for government [just a "layman" with some old university pals in the Cabinet] to start taking seriously the possibility – however remote – that Corbyn is right. If he is, that will have big implications for agriculture, tourism, transport, aviation policy and the economy as a whole.”

    BoJo then dives off the psychological deep-end, “Of course it still seems a bit nuts to talk of the encroachment of a mini ice age. But it doesn’t seem as nuts as it did five years ago [oh yes, it does]. I look at the snowy waste outside, and I have an open mind.” Open minded ? About things that have been established as reality ? I suppose we should stay open minded about the entire field of Chemistry or Physics, then ? Or how about the Theory of Gravity ? Was Boris being open minded about gravity when he took to the harness and wire during London 2012 ?

    Am I giving “oxygen” to the madness of the global warming deniers by writing about this truly ill-informed opinion from Boris Johnson ? The media are already giving more than enough oxygen to people in high office with quaint, outdated views. Should I be silent as major newspapers continue to pour forth ineptitude ?

    Am I “scoring an own goal” by pointing out his piece is a travesty of the scientific facts ? No, I am pointing out that his article contains invalid scientific opinion.

    When I first read this piece, I thought it was a parody, but now I’m not so sure. It appears to be a deliberate attempt to skew the confidence of other people – confidence in the main body of science, and the decades of patient work by people with thousands of data sets of measurements from the natural world, not just poor memories of winters past.

  • London Skies

    Yesterday evening, I was caught by the intensity of the London Sky – there was little air movement in most of the lower summer-heat space above the city, and virtually no cloud except very high strands and sprurls and bones and smears.

    Most of the cloud was clearly the result of aeroplane contrails – numerable to small children and their educational grandparents on various buses.

    As the sun began to set, or rather, as the Earth rolled to curve away from facing the sun, the sky took on the colour of bright duck egg blue with a hint of pale green, and the sprays of high contrail-cloud took on a glorious orange-fuchsia colour with flashes of gold, bronze and vanadium reds, fading slowly to chromium reds as twilight approached.

    At a certain moment, I understood something – as I watched an aeroplane high up, make its way west to Heathrow, the angle of the sunset showed its contrail as a murky ink, messing up the rest of the clouds as it brushstroked its way along, with its slate and muddy hues. As I watched, other parts of the clouds began to appear brown and grey, and since I knew that most of the cloud was jet engine exhaust that hadn’t moved because of the lack of high winds, I finally realised I was watching dirt, high up in the troposphere – careless, unthinking toxic waste.

  • Obey the Future

    Posted on August 5th, 2012 Jo No comments

    Disobedience only gets you so far. Resistance can be fertile, but intellectual ghettos can be futile. The human tendency to generalise creates too much negativity and prevents us from being constructive. We complain about the “evil” oil and gas companies; the “greedy” coal merchants and their “lying” bankster financiers; but refuse to see the diamonds in the mud.

    We should obey the future. In the future, all people will respect each other. There will no longer be war propaganda carried by the media, demonising leaders of foreign countries, or scorn for opposing political parties. In the future, human beings will respect and have regard for other human beings. So we should live that future, live that value, have care for one another. I don’t mean we are obliged to give money to charity to help needy people in poor countries. I don’t mean we should campaign for our government to commit funds to the Climate Finance initiatives, whose aim is to support adaptation to climate chaos in developing countries. No, charity is not enough, and never matches the need. Philanthropy will not answer climate change, and so solutions need to be built into the infrastructure of the global economy, sewn into the design, woven into the fabric. There should be no manufacture, no trade, no form of consumption that does not take account of the climate change impacts on the poor, and on the rich, on ecosystems, on ourselves.

    Yes, it’s true that corporations are destroying the biosphere, but we cannot take a step back, grimace and point fingers of blame, for we are all involved in the eco-destructive economy. We are all hooked on dirty energy and polluting trade, and it’s hard to change this. It’s especially hard for oil, gas and coal companies to change track – they have investors and shareholders, and they are obliged to maintain the value in their business, and keep making profits. Yes, they should stop avoiding their responsibilities to the future. Yes, they should stop telling the rest of us to implement carbon taxation or carbon trading. They know that a comprehensive carbon price can never be established, that’s why they tell us to do it. It’s a technique of avoidance. But gathering climate storms, and accumulating unsolved climate damages, are leading the world’s energy corporations to think carefully of the risks of business as usual. How can the governments and society of the world help the energy companies to evolve ? Is more regulation needed ? And if so, what kind of political energy would be required to bring this about ? The United Nations climate change process is broken, there is no framework or treaty at hand, and the climate change social movement has stopped growing, so there is no longer any democratic pressure on the energy production companies and countries to change.

    Many climate change activists talk of fear and frustration – the futility of their efforts. They are trapped into the analysis that teaches that greed and deceit are all around them. Yet change is inevitable, and the future is coming to us today, and all is quite possibly full of light. Where is this river of hope, this conduit of shining progress ? Where, this organised intention of good ?

    We have to celebrate the dull. Change is frequently not very exciting. Behind the scenes, policy people, democratic leaders, social engineers, corporate managers, are pushing towards the Zero Carbon future reality. They push and pull in the areas open to them, appropriate to their roles, their paid functions. Whole rafts of national and regional policy is wedded to making better use of energy, using less energy overall, displacing carbon energy from all economic sectors.

    And then there’s the progressive politics. Every leader who knows the shape of the future should strive to be a Van Jones, or a Jenny Jones, any green-tinged Jones you can think of. We should enquire of our political leaders and our public activists what flavour of environmental ecology they espouse. We should demand green policies in every party, expect clean energy support from every faction. We should not only vote progressive, we should promote future-thinking authority in all spheres of social management – a future of deeper mutual respect, of leaner economy, of cleaner energy.

    The future will be tough. In fact, the future is flowing to us faster than ever, and we need resilience in the face of assured destructive change – in environment and in economy. To develop resilience we need to forgo negativity and embrace positivity. So I ask you – don’t just be anti-coal, be pro-wind, pro-solar and pro-energy conservation. Where leaders emerge from the companies and organisations that do so much harm, celebrate them and their vision of a brighter, better, lower carbon future. Where administrations take the trouble to manage their energy use, and improve their efficiency in the use of resources, applaud them, and load them with accolades. Awards may be trite, but praise can encourage better behaviour, create exemplars, inspire goodly competition. Let us encourage the people with good influence in every organisation, institution and corporation. Change is afoot, and people with genuine power are walking confidently to a more wholesome future.

    Protect your soul. Don’t get locked into the rejection of evil, but hold fast to what is good. Do not conform to the patterns of this world, but be transformed by the renewing of your minds. Be strong for goodness, even as you turn your back on a life of grime.

    Live the Zero Carbon future, and make it come as soon as it can.

  • Just like they said it would be – how extreme weather is proving climate change theory

    Posted on July 11th, 2012 Jo No comments

    Nature has been sending a strong, chaotic message to many people in the last few months – drought, floods, storms, and very unusual temperatures and weather events.

    Public communicators of science have been explaining the underlying phenomena – the ENSO cycle in the Pacific Ocean has been flipping winds and sea surface temperatures from a condition known as La Nina, towards the El Nino configuration; plus, in the northern hemisphere, wind flow high above our heads has been erratic.

    Scientists have been careful not to claim every extreme weather event as proof of climate change theory. After all, any one violent storm or unprecedented high could be just that – freak – never to be repeated. Climatologists instead talk of “loading the climate dice”, a way to explain that extreme weather is more likely in a warming world.

    Reticence and restraint are in evidence, however, now is a prime moment to assert, without triumphalism, that all this crazy weather does indeed offer confirmation of climate change theory – everything is happening just the way the atmospheric scientists said it would.

    Arctic amplification

    There is no doubt that surface of the Earth is warming up, and the Arctic region of the globe is warming faster than anywhere else. This is to be expected in a world with added Greenhouse Effect from rising carbon dioxide levels in the air. The climatologists projected that this would happen, due to localised additional heating resulting from the side effects of melting ice, snow and permafrost in the northern pole. Antarctica, on the other hand, would not show the same kind of strong “albedo” feedback response as it was still too cold and ice-and-snow bound and surrounded by isolating ocean and wind currents.

    Up there, where the air is clear

    Scientists predicted that because of Arctic amplification, the profile of the planet’s atmosphere would change under global warming conditions. And so it has. The tropopause – the place where the lower, thicker atmosphere – the troposhere – meets the upper, thinner stratosphere, has shifted, and the temperature change profile or “inversion” at this height has also been modified. While the air close to the Earth’s surface has become warmer, the air in the stratosphere has become colder. All just as the scientists predicted would happen.

    Jet stream weaker and loopier

    Close to the surface of the planet, wind tracks and the passage of storms, pressure systems and clouds are turbulent and pretty chaotic. But above this zone, winds flow freely. The winds stream because the atmosphere drags whilst the Earth turns. Because of the general patterns of billowing air below them, jet streams are usually centred at particular places – the polar jets at around 30 degrees angle from the poles, the subtropical jets at around 30 degrees from the Equator.

    Atmospheric scientists have been monitoring these winds for change, as the models indicated that the northern polar jet, in particular, would shift its position northwards, because of the other climate changes, and weaken. As it weakened, they worked out that the normal wavy kinks in the jet stream would become big loops, and maybe even lock into certain shapes for longer than usual, a situation known as a blocking event.

    Wobbly weather

    Because jet streams have an impact on the movement of weather systems further down, the scientists projected that the more meandering jet stream would carry weather systems out of their usual tracks, and also create bubbles of unusual temperature. Normally cold places would see heatwaves, normally hot places would have cold snaps, and everywhere would experience unseasonal and more extreme weather. And this is exactly what we have been seeing.

    The number of freak weather events is mounting, along with insurance company manager blood pressure readings. The flooding and drought that would be expected with the periodic Pacific ENSO system flip from La Nina to El Nino have been highly damaging, and when the final accounting is done, probably more damaging than previously.

    The food on the table

    Climate change scientists have long predicted altered patterns and increased variability of rainfall with global warming. There are real concerns that farmers can no longer predict when, or for how long, it will rain, and this is affecting major food growing regions. The major global rice, wheat and maize corn harvests are at risk, and recent years of failings have dented confidence and ballooned prices.

    Strange weather is impacting on fruit and vegetable growing, as seasons are becoming unclear and even swapping their normal order. The weather has gone wrong, and this is exactly what the scientists have been warning us about for several decades in official reports. How much easier would we have accepted changing realities if we had understood the language of the early research papers from the Intergovernmental Panel on Climate Change !

  • Ocean Warming : False Security

    Posted on May 3rd, 2012 Jo No comments

    The human race has been treating the World Ocean as a dumping ground for global warming and excess carbon dioxide emissions.

    It’s where most of the heat ends up, and almost half the anthropogenic carbon dioxide emissions as well.

    Research shows that as humanity pours more carbon into the sky, the oceans are able to react by taking up more of it.

    The Southern Ocean in particular is showing a healthy response, pulling more and more of our emissions down from the atmosphere.

    On the face of it, the oceans are increasing their capacity to suck carbon out of the air, either by biological means or through simply mixing with the air, so some argue that we should relax and rely on these carbon sinks to avert dangerous warming of the ground level atmosphere – maintaining a healthy atmosphere for all land-based life.

    However, this net reduction in atmospheric carbon dioxide due to this increased ocean carbon pump is masking the effects of global warming – for the time being. The oceans are warming, and this combined with increased overturning is resulting in the oceans giving up more carbon dioxide from their depths as a result.

    For now, the ocean carbon sink is holding up and compensating for some global warming, but there are concerns should the carbon pump fail, or the effects of global warming overtake it.

    The very latest research into changes in the World Ocean show clear trends in salinity – how fresh or how salty seawater is. These changes are associated with the higher energy in the Earth system : more heat captured by the ocean is making wind patterns more powerful, which makes ocean overturning stronger.

    Of special concern is the effect this could have on the Southern Ocean. A stronger overturning would increase the upwelling of deep ocean water, which would draw long-sequestered carbon-rich gases from the deeps to the surface of the sea, where it would outgas to the atmosphere.

    This is the scenario recently suggested to explain part of the process of how the Earth came out of the last glacial period over 15,000 years ago (“What causes the CO2 rise?”)

    The biological productivity of the oceans, the levels of greenhouse gases in ocean water, and the strength of the carbon sinks will continue to be of intense concern as time passes.

    Walking out to buy a few household essentials from the corner shop, I ran into somebody I’ve known since my childhood, practically, returning from the drycleaners with two trailing kids in tow.

    “Happy Spring !” I said, and smiled, and pointed out the lovely blossom on the urban street tree. Eldest child grumbled about hayfever. Parent mentioned April Showers.

    “It’s been the wettest drought, ever !”, proclaimed eldest child, who I noticed was wearing a Team GB tracksuit and therefore probably up to speed with current events. “It has been rather damp”, I admitted, “and yet the drought’s not over yet. If you look at the Met Office records, you can see we’re still not up to normal levels of rainfall. And it was like this last year.” “And the year before that”, added parent, “although I expect for this month it might show we’ve had quite a lot more than normal.” (Select “Rainfall”)

  • The Island Prescient

    The message today is taken from the Book of Psalms, chapter 104, an anthology of holy songs recognised by both Jews and Christians as being divinely inspired.

    I have heard and read some Christian leaders, including North Americans and Australians, claim that global warming isn’t happening, because they believe that the Bible teaches that dangerous sea level rise is impossible, based on the contents of verses 5 to 9.

    “You set earth on a firm foundation
    so that nothing can shake it, ever.
    You blanketed earth with ocean,
    covered the mountains with deep waters;
    Then you roared and the water ran away –
    your thunder crash put it to flight.
    Mountains pushed up, valleys spread out
    in the places you assigned them.
    You set boundaries between earth and sea;
    never again will earth be flooded.” (The Message)

    These verses contain a reference to the Noah’s Ark story – the Biblical account that encapsulates a very widespread oral tradition of worldwide inundation. Some scientists believe these narratives are an echo of very real events, and that the Epic of Gilgamesh also records severe drought (corresponding to the Bible story of Joseph in Egypt):-

  • The Truth Is Relative

    Posted on March 30th, 2012 Jo 1 comment

    Image Credit : BBC

    Many ordinary people, when asked about global warming and climate change, offer views they’ve read or heard somewhere, often using the word “could”, because that word appears a huge lot in public communications and media, especially television. “The world could warm by as much as four degrees by the end of the Century.” “Rain-fed agriculture in southern Europe could be gone by 2050″. “Thames Water could end up having to buy water from Scotland”. That kind of thing.
    However, when asked about their own personal views, people often show reluctance to commit. And so it appears that the one thing they really believe is that truth about global warming and climate change is relative.

    So, for many people, the truth is relative. And why should that be ? Maybe people don’t want to be known to have an actual opinion because they fear that if they show commitment to one view or other, they might cause an argument because other people around them think differently. After all, it’s hard to know which people are climate change “accepters”, and which people are strongly against the facts emerging from the science of atmospheric physics.

    So people, when surveyed, will not state their own views on what they think is a hot button topic. They will cite public scientists, and other well-known public figures – regardless of their actual knowledge. By deferring to the opinions of others, people delegate the matter of deciding where they themselves stand. People often admit that they themselves don’t know the truth, but somebody else, surely, does.

  • Debunking the GWPF Briefing Paper No2 – The Sahel Is Greening

    Posted on March 16th, 2012 Jo No comments


    Image Credit : Global Warming Policy Foundation

    This article was written by M. A. Rodger and was originally posted at DeSmogBlog and is syndicated by an informal agreement and with the express permission of both the author and DeSmogBlog, without payment or charge.
    This is the second in a series of posts on the educational charity and climate sceptic “think-tank” Global Warming Policy Foundation (GWPF). The first post examined GWPF”s organisation and its principles (or lack of them). Here we examine GWPF”s Briefing Paper No2 – The Sahel Is Greening by Philipp Mueller who is the Assistant Director of the GWPF. Coverage of the greening Sahel has been in the media for a decade now, so this cannot be too controversial a subject, can it?

    GWPF BRIEFING PAPER No2 – SIGNIFICANCE OF THE SUBJECT
    Mueller explains what this Briefing Paper No2 is about in the first three sentences.

    “Global warming has both positive and negative impacts. However, very often only the negative consequences are reported and the positive ones omitted. This article will show an example of a positive effect of warming.” 

    Mueller then sets out to show how the Sahel is enjoying a “positive impact” of global warming.

    Yet already here is a glaring omission. Despite this being an ideal opportunity to list out all the other “positive impacts”, Mueller fails even to hint at what any of the others might be. Never mind. We still have the Sahel. Or do we?

    THE GREENING OF THE SAHEL – MUELLER”S VERSION
    Mueller”s account can be summarised thus:

    Between the 1950s and 1980s reducing rainfalls across the Sahel (the region of Africa immediately South of the Sahara Desert) caused severe drought and famine. But, according to Mueller, since the early 1980s this process has gone into reverse with the Sahel greening, harvests more plentiful and the Sahara shrinking.

    The reason for this improvement is more than simply increasing rainfall. The climate of the Sahel region is delicate. Additional rainfall results in higher levels of vegetation. This induces yet more rain while reducing soil erosion. However, there is more at work than just this one “feedback” mechanism. Mueller says the extra factor that might be responsible is “the rise of atmospheric CO2 levels.” It seems the elevated levels of atmospheric CO2 let plants grow better, especially in arid regions. Clever stuff, that!

    Mueller does not leave it there. He discusses the cause of the underlying increase in rainfall citing papers that suggest the rainfall was due to a warmer climate in the Sahara or a warmer North Atlantic, a process “partially caused by greenhouse gas emissions.”

    Mueller”s shrinking Sahara is not unprecedented. In the past the Sahara, far from being a desert, was once a grass-covered savannah. This was over 6,000 years ago during the Holocene Climate Optimum (when temperatures were 2-5 deg C hotter than now according to Mueller but not according to others) and also during two other times in last 120,000 years.

    Mueller says the future isn”t certain. The Sahel may become wetter or it may become drier. But, he concludes, today the Sahel is undoubtedly wetter and suddenly Mueller becomes far more certain about those speculative causes of the greening of the Sahel.  “The increase in rainfall, which was probably caused by rising temperatures, and rising CO2 concentrations, might even – if sustained for a few more decades – green the Sahara. This would be a truly tremendous prospect.”

    This account makes bold statements but can it all be true?

    DO PIGS FLY?
    Mueller”s account contains many omissions and misrepresentations. The list is so long that the full account of Mueller”s errors are appended to the bottom of this post and just a summary is presented here.

    After droughts end, things grow greener. That is natural. The Sahel has a delicate climate and research shows that increased human emissions were more likely the cause of the initial drought rather than the cause of the re-greening. The recovery is also very patchy. Drought and famine, declining crops as well as encroaching deserts continue to plague parts of the Sahel, to the point that the description “greening” remains a subject for debate. Mueller”s rosy account fails to tell us any of this.

    It is wild speculation to assert that any recovery in the Sahel is a result of global warming and to dangle the prospect of a future green Sahara is the exact opposite of the message provided by Mueller”s reference on the matter. However welcome the re-greening of parts of the Sahel, it cannot be relied on.

    Mueller does mention this in passing but he fails to mention the confident scientific finding that any re-greening will eventually be reversed in the future. So if this greening of the Sahel is the prime example of the “positive impacts” of global warming, it is no surprise that Mueller fails to list any of the others.

    CONCLUSION
    GWPF Briefing paper No2 is an entirely flawed document. The views it expresses are those of the author (as the disclaimer on the cover says), not those views of the GWPF. Yet the author works with a “distinguished team of GWPF Academic Advisors.” Further, it remains a wonder that a registered charity whose task is to educate the public on global warming could ever put its name on such a report. If this is representative of GWPF Briefing Papers as a whole, it would be a cause of grave concern.

    A second GWPF Briefing Paper will be the subject of the next post in this series. Hopefully it will prove to be more factual in nature than Briefing Paper No2.

    APPENDIX – Details of Omissions & Misrepresentations within Mueller”s paper.

    A1 – OMISSION
    Mueller”s account began with mention of a drought between the 1950s & 1980s. This drought requires greater consideration than just a mention. Would we not expect a region to become greener in the period following a drought? Strangely, while Mueller discusses theories for the greening, he fails to mention the causes of the initial drought and its continuing legacy. This is not some minor event. The drought has been described as “…among the most undisputed and largest recent climate changes recognized by the climate research community.”

    The causes of the drought have slowly become better understood. Rising population and over-grazing by livestock was the first theory but studies now show the drought resulted from changes in ocean surface temperatures Folland et al (1986) Giannini et al (2003)which are likely due in part to the sulphate aerosol pollution of Europe and North America Rotstayn & Lohmann (2002) Biasutti & Gainnini (2006) and thus it is the cleaning of emissions from power stations that has likely allowed the rains to return.

    Mueller remains entirely silent about the potential role of sulphate aerosols in causing the drought and the subsequent greening. It is difficult to understand his silence as these findings are well known. Perhaps the potential role of human pollution in causing a “devastating drought” sits too uncomfortably with the intended message of “positive impacts” from global warming.

    A2 – OMISSION
    To emphasis his “positive impact”, Mueller tells us the greening is “a very welcome and very beneficial development for the people living in the Sahel.” What Mueller omits to tell us is that conditions have yet to return to the levels seen in the 1950s and that drought and famine still stalk the Sahel. His rosy reporting is even used by one sceptical commentator as proof that the continuing drought in the Sahel is but a “pseudo-catastrophe.”

    Climatology may not provide the best reports of the events but the Sahel drought is reported in newspapers and the humanitarian aid networks. “In 2005, drought and famine hit the Sahel, claiming many lives. The pattern was repeated in 2010 with the crisis most acute in Niger. And now the early warning signs are there for problems again in 2012.” For Mueller to entirely miss such prominent reporting in the age of the internet is truly remarkable!

    A3 – OMISSION
    It is also remarkable how Mueller writes of improving agricultural outputs across the Sahel. Mueller cites the findings of Chris Reij in a small region of Burkina Faso and also Olsson (2008), from where he quotes half a sentence about improved agricultural output in Burkina Faso and Mali.

    What Mueller totally misses in Olsson”s paper is the preceding sentence and the following half sentence which says – “After many years of dwindling food production in the Sahel, only two countries show signs of improved agricultural performance. …while the other Sahelian countries show decreases in their production.” So Mueller omits to mention the situation in the other nine countries of the Sahel, instead concentrating on the two countries where the evidence doesn”t directly contradict his theorizing.

    A4 – MISREPRESENTATION
    To reinforce his greening Sahel message Mueller strays geographically. He embellishes part of a Heartland Institute report that quotes a second-hand report from geologist Stephan Kropelin.

    This concerns greening within the deserts of Western Sahara, a much-troubled country that is in Africa but definitely not part of the Sahel! It is from the same Heartland report that Mueller times the start of the greening as “since the early 1980s” when if he had read the other more reliable references he cited he would have known the greening began in 1994.

    The entirety of the Sahel is not greening as Mueller would have us believe. It is patchy and there remains enough areas still suffering encroaching desert to make the term "greening" debatable. Somehow Mueller fails to notice.

    A5 – MISREPRESENTATION
    Mueller does manage to notice that there are signs of greening even in some areas where rainfall is still decreasing. Mueller asserts this might well be due to increased levels of atmospheric CO2. To support his CO2 claim Muller cites Sherwood Idso who has long espoused such theories and claims certain forest studies show evidence of it

    But when it comes to the greening of the Sahel, Idso makes clear the CO2 link is only speculation and makes do with pointing out where researchers fail to mention his brave theorising.
    There is one logical problem with Mueller”s claim which may be why Idso does not pursue a similar argument. It is difficult to reconcile patchy Sahel greening with a widespread (indeed worldwide) phenomenon like rising CO2 levels. The most likely reason for patchy greening (other than patchy rainfall) is very, very, widely discussed and observed on the ground. It is farmers changing their methods of cultivation, something Mueller fails to even mention, preferring instead to advance his ridiculous CO2 claim

    A6 – MISREPRESENTATION
    The prehistoric green Sahara of the mid-Holocene with its lakes and rivers is used by Mueller to reinforce his argument that global warming may trigger a return to such conditions and so provide a truly tremendous “positive impact” from global warming. Again he manages to misrepresent the words of others. On this matter Mueller concludes “(Professor Martin) Claussen has considered the likelihood of a greening of the Sahara due to global warming and concluded that an expansion of vegetation into today”s Sahara is possible as a consequence of CO2 emissions.”

    This is an exceedingly bizarre interpretation of the source document! Claussen”s quote actually says “some expansion of vegetation into today”s Sahara is theoretically possible”,(end quote, emphasis added) words too pessimistic for Mueller so he changed them.

    Not only does Mueller misquote Claussen, he wholly ignores the explicit warning that Claussen makes against any belief in a future green Sahara. “But he(Claussen) warns against believing the mid-Holocene climate optimum will be recreated.” This source document continues by pointing to the continuing tree-loss in the Sahel and the shrinkage of Lake Chad; this despite the improved levels of rainfall.

    Indeed, Claussen is not alone in dismissing a green Sahara.  Yet Mueller”s report concludes that a green Sahara is a distinct possibility, the exact opposite of the very authority that he claims is supporting his conclusions.

    A7 – OMISSION
    Finally, Mueller is silent about one “negative impact” of a greening Sahel. He intimates that any greening due to global warming will be permanent but this is incorrect. Climatology shows that the Sahel has a very sensitive climate such that it can be stated “with confidence” that “any greening of the Sahel and Sahara in the near future will eventually be reversed.”  The greening is unreliable. It is thus hardly an encouraging example of a “positive impact” from global warming.

  • The Last Battle

    Posted on January 15th, 2012 Jo 2 comments

    The “Statue of Liberty” or Saint John’s Lamb of God ?

    Britain’s real enemy is not Iran.

    The real enemy is the mismanagement of the Earth’s energy resources.

    The last battle is to overcome the misdeeds of those who have commandeered and wasted the Earth’s energy resources – and that includes ourselves.

    It should not be a violent dispute, for aggression and the use of weapons are morally unjustifiable. But all the same, it will be a genuine, Titanic, struggle.

    As C. S. Lewis portrays with so much resonance, it matters little under which flag or title we serve or belong – what matters is our allegiance to the precepts of divine honour, holy devotion and right dealings with other people :-

    “Why did the faithful Taarkan end up getting to come into Narnia ? Usually Lewis writes allegorically so is he trying to tell us something when a worshipper of Tash is allowed to enter the new Narnia ? Any thoughts ? …It wasn’t the name that mattered, but rather the conduct of the Taarkan and how he chose to see and do things. He didn’t believe in the cruelty and underhanded ways his countryman were doing things, but rather in honour and a code of conduct. So even though the Taarkan thought he was worshipping Tash, the whole time he was actually worshipping Aslan [Turkish for "Lion"] through his thoughts and deeds. So when the time came for the end of the world and judgement, he was placed where his heart had always led him.”

    For those who recognise the twin threats from climate change and energy depletion, we realise that there is hard work ahead. Our natural aim is to protect ourselves; and the moral consequence is that we are obliged to protect the other – because both climate change and energy depletion are global problems.

    Climate change hits the poorest the hardest – already, significant changes in rainfall and weather patterns have created long-term drought, encroaching coastal and inland inundation, crop losses and enforced migration. And it’s only going to get worse. It’s so terrible we could not even wish it on our enemies – it teaches us that nobody is an enemy.

    To solve climate change, we need to change our energy systems. Some hail the depletion of hydrocarbon and coal energy resources as a gift that will help us resolve the emissions problem and prevent dangerous climate change, by making a virtue of necessity – but the situation is not that simple.

    The reaction of the world’s authorities, wealth controllers and corporate proprietors to the winding down of fossil fuel energy resources has so far been complex, and there are many indications that warfare, both military and economic, has been conducted in order to secure access to energy.

    This may be the way of the lion in us all, but it is not the way of The Lamb. The Lamb sacrifices all that others value so that he is qualified to bring about a new universal regime of peace and responsible autonomy – a kingdom of priests, pastors with mutual respect.

    We are called to become good stewards of each other and the Earth. The gentle Lamb of God will judge our hearts.

    The Book of the Revelation to Saint John the Divine, Chapter 4 :-

    “…I looked and saw a door that opened into heaven. Then the voice that had spoken to me at first and that sounded like a trumpet said, “Come up here ! I will show you what must happen next.” Right then the Spirit took control of me, and there in heaven I saw a throne and someone sitting on it. The one who was sitting there sparkled like precious stones of jasper and carnelian. A rainbow that looked like an emerald surrounded the throne. Twenty-four other thrones were in a circle around that throne. And on each of these thrones there was an elder dressed in white clothes and wearing a gold crown. Flashes of lightning and roars of thunder came out from the throne in the center of the circle. Seven torches, which are the seven spirits of God, were burning in front of the throne. Also in front of the throne was something that looked like a glass sea, clear as crystal…And as they worshiped the one who lives forever, they placed their crowns in front of the throne and said, “Our Lord and God, you are worthy to receive glory, honour, and power. You created all things, and by your decision [and for your pleasure] they are and were created…”

    The Book of the Revelation to Saint John the Devine, Chapter 5

    “In the right hand of the one sitting on the throne I saw a scroll that had writing on the inside and on the outside. And it was sealed in seven places. I saw a mighty angel ask with a loud voice, “Who is worthy to open the scroll and break its seals ?” No one in heaven or on earth or under the earth was able to open the scroll or see inside it. I cried hard because no one was found worthy to open the scroll or see inside it. Then one of the elders said to me, “Stop crying and look ! The one who is called both the `Lion from the Tribe of Judah’ and `King David’s Great Descendant’ has won the victory. He will open the book and its seven seals.” Then I looked and saw a Lamb standing in the center of the throne…The Lamb looked as if it had once been killed. It had seven horns and seven eyes, which are the seven spirits of God, sent out to all the earth. The Lamb went over and took the scroll from the right hand of the one who sat on the throne. After he had taken it, the four living creatures and the twenty-four elders knelt down before him. Each of them had a harp and a gold bowl full of incense, which are the prayers of God’s people. Then they sang a new song, “You are worthy to receive the scroll and open its seals, because you were killed. And with your own blood you bought for God people from every tribe, language, nation, and race. You let them become kings and serve God as priests, and they will rule on earth.”"

    Leaders of the powerful nations – put aside your death-hastening technology.

    Let there be a low carbon energy peace on a climate-stable Earth.

    “…Understand, then, that those who have faith are children of Abraham. Scripture foresaw that God would justify the Gentiles [non-Jewish people] by faith, and announced the gospel [good news of God's love and forgiveness] in advance to Abraham: “All nations will be blessed through you.” So those who rely on faith are blessed along with Abraham, the man of faith…”

There is neither Jew nor Gentile [non-Jewish person], neither slave nor free, nor is there male and female, for you are all one in Christ Jesus. If you belong to Christ, then you are Abraham’s seed, and heirs according to the promise.”

    [ UPDATE : No, I have not taken leave of any of my senses. I was in church, All Saints in Highams Park, London E4, and many thoughts arose as I contemplated the stained glass window, with its Suffering Servant Messenger King/Lord/Master, rainbow, Alpha, Omega, Noah's dove with the sprig of olive; and listened to the reading from Revelations 4; and sang "Be Thou My Vision" with the congregation; and considered what Epiphany the world needs at this time of intense war propaganda. There are those who declare themselves as Christian who claim that war with Iran is prophesied. This may be a fringe view, but the narrative infects major political discussion in the United States of America : "The problem, of course, is that rhetoric can have political effects that narrow the options available to decisionmakers. If you've publicly declared Iran's nuclear program sufficiently threatening to warrant initiating a potentially catastrophic war and then sanctions fail to achieve their defined goal, you may have a hard time walking back from that threat." ]

  • The Storm

    Posted on December 30th, 2011 Jo No comments

    On my Christmas journey, on the train from Brussels, Belgium, to the Dutch border, besides the wind turbines, I counted the number of solar electric rooftop installations I could see. My estimate was that roughly 300 kilowatts of solar could be seen from the track.

    There has been an explosion of deployment. The renewable energy policies that are behind this tide of photovoltaics in Flanders seem to be working, or have been until recently.

    On my journey back from Holland to England, I pondered about the polders and the low-lying landscape around me. I don’t know what river it was we crossed, but the river was only held in place by narrow banks or dikes, as it was higher than the farmland around it – waterlogged fields in some places – where parcels of land were divided by stillwater ditches instead of hedges or fences.

    “Oh no, we don’t have “Mary Poppins” on Dutch TV any more at Christmas every year like we used to. We’re going to see the film “The Storm”…” said my host. Curiouser and curiouser. “De Storm” is a film that harks back to an actual historical event, the major North Sea flooding in 1953. “I remember what it was like afterwards,” says an older English relative, “I visited Belgium and Holland with my aunt and uncle just after the flooding – he wanted to visit the family war graves. We stayed in Middelburg. You could see how high the water reached. There were tide marks this high on the side of the houses, and whelks left stuck on the walls.”

    The film attempts to nail down the coffin casket lid of bad weather history. By telling the narrative of major, fearful floods of the past, people are distracted from the possibility that it may happen again. History is history, and the story tells the ending, and that’s a finish to it.

    However, for some people, those people who know something of the progress of the science of global warming, this film is like a beacon – a flare on a rocky landing strip – lighting the way to the future crash of the climate and the rising of sea levels, which will bring havoc to The Netherlands, Dutch engineers or no Dutch engineers.

    We have to be prepared for change, major change. If you or anyone you know has Dutch relatives and friends, think about whether you can invite them to live with you in future if things get really bad. One or two really bad storms combined with excessive tides and a few centimetres of sea level rise could be all it takes to wreck the country’s ability to organise water and destroy a significant amount of agricultural land.

    “I’ve been studying Climate Change science”, I told another host. “You believe in Climate Change ?”, he asked, somewhat incredulously. “It’s 200 years of science”, I replied, smiling, “but we probably shouldn’t discuss it. I don’t think it would be very productive.”

    Something not completely dissimilar to a hurricane or a typhoon has been gusting at incredibly high speeds through the lowlands of Scotland today – and further afield.

    Yet, regardless of whether this heralds the start of a proper snow-and-ice winter, it’s not likely to prevent 2011 being one of the hottest years ever.

    July and August, worldwide, were nearly the hottest on record in 2011. Meanwhile, the Blob Chart tells the story in a way that nobody can deny.

    Meanwhile, in Durban, South Africa, the world’s governments struggle to make sense. A healthy economy is a carbon-emitting economy – because industrial energy causes high carbon emissions. What needs to happen is that the energy production businesses start to diversify their portfolio – increasing the amount of energy they produce from renewable, sustainable low carbon resources, whilst decreasing the amount of fossil fuel energy they supply.

    It can’t be left to individual “big hitters” to kick-start the renewable energy revolution – it requires transnational, international, multi-national and national energy companies to start to displace carbon from their products.

    If they don’t, they will face mass disinvestment, as ethical concerns rise up the agenda of investor groups and funds. So, BP, Shell and Exxon Mobil – if you don’t start switching from selling us hydrocarbons to selling us renewable energy, your businesses will under-compete. You have been notified.

  • Occupy your mind #7

    Posted on October 27th, 2011 Jo No comments

    So, after rumours and quashings of rumours, Giles Fraser has resigned as canon chancellor of St Paul’s Cathedral, “resigned in protest at plans to forcibly remove demonstrators from its steps, saying he could not support the possibility of “violence in the name of the church”…Fraser, a leading leftwing voice in the Church of England, would resign because he could not sanction the use of police or bailiffs against the hundreds of activists who have set up camp in the grounds of the cathedral in the last fortnight.”

    But just why did Giles Fraser resign ? What has it achieved ? What could it possibly achieve ? Now he’s no longer in the Cathedral organisation he cannot influence what happens. What pressures has he had to endure behind the scenes that gave him no option but to jump ?

    Somebody I know has been praying that there would be heavy rain in London, just so the conditions would be impossible for the Occupyer camp to continue; that they would have to pack up and go home.

    What on Earth is this @OccupyLSX protest for ? A camp of principle, to defend the right to protest ? A camp of demands, pursuing a just economics and a just society ? A camp of non-violence, when it deliberately provokes a stand-off between demonstrators and police forces ? How can the Occupyers claim to be peaceful when they know their actions have a fragmentation bomb-like effect on the society around them ? How can the Cathedral Campers evidence their intentions for a juster, saner, economic system, when the net effect of their actions is likely to be a huge law court struggle at taxpayer expense ? It’s not a revolution, it’s an irritation – or at least that is the way that it will continue to be viewed by the governing authorities.

    Somebody on the inside track of campaigning in London has told me that the Occupy protest is destined to transmogrify into a Climate Refugee tent city in late November, early December. If it survives that long, then at least it can claim to be a piece of living art reflecting what is happening around the world because of climate change disasters.

    Unless and until the Occupyers can take on relevance, everybody with even just a slightly-left-of-centre agenda will attempt to co-opt the Occupy London camp for their own purposes.

    Remember, dear Occupyers, you are not “rising up” like the people in Libya – they were supplied with arms from around the world, forces overt and covert from Qatar, Europe and quite possibly America, and fed into a huge psychological operations narrative, ably supported by the media.

    The Libyan conflict wasn’t about Colonel Muammar Gaddafi, may he rest in peace. The information management of the North African and Middle Eastern unrest shows that mass propaganda still works, and that media consumers continue to fall for the same fabrications, time after time.

  • Adam Curtis : Chaotically Unstable

    Posted on June 5th, 2011 Jo 1 comment

    I’m looking quizzical, rubbing my chin. Adam Curtis appears to have lost control of his mind, or at the very least, is showing signs of unhealthy self contradiction. Where are the checks and balances ?

    At the start of Part 2 of “All Watched Over by Machines of Loving Grace”, he unpicks, and, I would suggest, stamps on, the idea that ecosystems are networks of feedback loops, tending to re-balance. And then at the end of the same presentation, he asserts that human revolutions fail, and society folds in on itself and returns to the state of power and control it was in before. Now which is it to be, Adam Curtis ? Self-correcting stability or non-correcting ebbs, flows and shifting sands ?

  • Fiona Harvey : Astonishing Admissions

    Posted on May 30th, 2011 Jo No comments

    From the consistent and unrelenting rise in global carbon dioxide emissions, you would never have guessed that there’d been a downturn. But that’s because energy is cheap, and easily substitutes for economic production, labour and resources – within limits.

    Fiona Harvey has gathered and presents some astonishing admissions from various key speakers on the issue of emissions, ahead of the annual mid-year United Nations climate change talks in Bonn :-

    http://www.guardian.co.uk/environment/2011/may/29/carbon-emissions-nuclearpower

    “Worst ever carbon emissions leave climate on the brink : Exclusive: Record rise, despite recession, means 2C target almost out of reach : Fiona Harvey, Environment correspondent, guardian.co.uk, Sunday 29 May 2011 : Greenhouse gas emissions increased by a record amount last year, to the highest carbon output in history, putting hopes of holding global warming to safe levels all but out of reach, according to unpublished estimates from the International Energy Agency. The shock rise means the goal of preventing a temperature rise of more than 2 degrees Celsius – which scientists say is the threshold for potentially “dangerous climate change” – is likely to be just “a nice Utopia”, according to Fatih Birol, chief economist of the IEA. It also shows the most serious global recession for 80 years has had only a minimal effect on emissions, contrary to some predictions…”

  • No Connection

    Posted on May 24th, 2011 Jo No comments

    Many news articles now follow a predictable path. Some awe-inspiring, statistics-shaking weather event hits town – in the case of Joplin, literally. Then some people muse about whether these extreme events could have anything to do with Global Warming. Then some other people smother the idea very publicly. “No one weather event can be attributed to Climate Change !”, they insist, and yes, in the grand scheme of things they’re right – you cannot say for certain that one freak tornado, hurricane, flood or storm can be cast iron guaranteed to have been caused by atmospheric heating and increased sky water vapour. There is No Connection, official, and we can all breathe a sigh of relief and donate to a worthy clean-up cause.
