  • Peak Oil Redux

    Posted on July 22nd, 2016 Jo No comments

    Peak conventional crude petroleum oil production is apparently here already – the only thing that’s been growing global total liquids is North American unconventional oils : tight oil – which includes shale oil in the United States of America – and tar sands oil from bitumen in Canada – either refined into synthetic crude, or blended with other oils – both heavy and light.

    But there’s a problem with unconventional oils – or rather several – but the key one is the commodity price of oil, which has been low for many months, and has caused unconventional oil producers to rein in their operations. It’s hitting conventional producers too. A quick check of Section 3 “Oil data : upstream” in OPEC’s 2016 Annual Statistical Bulletin shows a worrying number of negative 2014 to 2015 change values – for example “Active rigs by country”, “Wells completed in OPEC Members”, and “Producing wells in OPEC Members”.

    But in the short term, it’s the loss of uneconomic unconventional oil production that will hit hardest. Besides problems with operational margins for all forms of unconventionals, exceptional air temperatures (should we mention global warming yet ?) in the northern part of North America have contributed to a seizure in Canadian tar sands oil production – because of extensive wildfires.

    Here’s two charted summaries of the most recent data from the EIA on tight oil (which includes shale oil) and dry shale gas production in the United States – which is also suffering.

    Once the drop in North American unconventionals begins to register in statistics for global total liquids production, some concern will probably be expressed. Peak Oil just might be sharper and harder and sooner than some people think.

  • Nigel Lawson : Unreferenced & Ill-Informed ?

    Posted on May 8th, 2014 Jo No comments

    An appeal was issued by David Andrews of the Claverton Energy Research Group, to respond to the Bath Lecture given by Nigel Lawson :-

    “Dear All, this group is not meant to be a mere venting of frustration and opinion at what is perceived to be poor policy. So what would be really useful is to have the Lawson spiel with the countering fact interspersed. I can then publish this on the Claverton web site which does get a lot of hits and appears to be quite influential. Can I therefore first thank Ed Sears for making a good effort, but ask him to copy his bits into the Lawson article at the appropriate point. Then circulate it and get others to add in bits. Otherwise these good thoughts will simply be lost in the wind. Dave”

    My reply of today :-

    “Dear Dave, I don’t have time at the moment to answer all of Nigel Lawson’s layman ruminations, but I have written a few comments here (see below) which begin to give vent to frustration typical of that which his tactics cause in the minds of people who have some acquaintance with the actual science. The sheer volume of his output suggests an attempt to filibuster proper debate rather than foster it. To make life more complicated to those who wish to answer his what I think are absurd notions, he gives no accurate references to his supposed facts or cites any accredited, peer-reviewed documentation that could back up his various emotive generalisations and what appear to be aspersions. Regards, jo.”

    Nigel Lawson: The Bath Lecture

    Climate Alarmism Is A Belief System And Needs To Be Evaluated As Such

    Nigel Lawson: Cool It

    Standpoint, May 2014

    This essay is based on the text of a speech given to the Institute for Sustainable Energy and the Environment at the University of Bath.

    There is something odd about the global warming debate — or the climate change debate, as we are now expected to call it, since global warming has for the time being come to a halt.

    [ : Contrary to what Nigel Lawson is claiming, there is no pause – global warming continues unabated. Of this there can be no doubt. All of the data that has been assessed – and there is a lot of it – confirms the theoretical framework – so it is odd that Nigel Lawson states otherwise, seemingly without any evidence to substantiate his assertion. Nigel Lawson appears to be taking advantage of fluctuations, or short-term wrinkles, in the records of air temperatures close to the Earth, to claim that up is down, dark is light and that truth is in error. Why are temperatures in the atmosphere close to the Earth’s surface, or “surface temperatures”, subject to variability ? Because heat can flow through matter, is the short answer. The longer answer is the interplay between the atmosphere and the oceans, where heat is being transfered between parts of the Earth system under conditions of flows such as the movement of air and water – what we call winds and ocean currents. There are detectable patterns in the flows of air and water – and some are oscillatory, so the temperature (taken at any one time) may appear to wriggle up and down (when viewed over a period of time). Despite these wobbles, the overall trend of temperature over several decades has been reliably detected. Despite Nigel Lawson’s attention to air temperatures, they are probably the least significant in detecting global warming, even though the data shows that baseline air temperatures, averaged over time, are rising. The vast proportion of heat being added to the Earth system is ending up in the oceans :-
    and the rise in ocean temperatures is consistent :-
    which indicates that circulatory patterns of heat exchange in the oceans have less effect on making temperatures fluctuate than the movement of masses of air in the atmosphere. This is exactly what you would expect from the study of basic physics. If you give only a cursory glance at the recent air temperatures at the surface of the Earth, you could think that temperatures have levelled off in the last decade or so, but taking a longer term view easily shows that global warming continues to be significant :-
    What is truly astonishing about this data is that the signal shows through the noise – that the trend in global warming is easily evident by eye, despite the wavy shakes from natural variability. For Nigel Lawson’s information, the reason why we refer to climate change is to attempt to encompass other evidence in this term besides purely temperature measurements. As the climate changes, rainfall patterns are altering, for example, which is not something that can be expressed in the term global warming. ]

    I have never shied away from controversy, nor — for example, as Chancellor — worried about being unpopular if I believed that what I was saying and doing was in the public interest.

    But I have never in my life experienced the extremes of personal hostility, vituperation and vilification which I — along with other dissenters, of course — have received for my views on global warming and global warming policies.

    For example, according to the Climate Change Secretary, Ed Davey, the global warming dissenters are, without exception, “wilfully ignorant” and in the view of the Prince of Wales we are “headless chickens”. Not that “dissenter” is a term they use. We are regularly referred to as “climate change deniers”, a phrase deliberately designed to echo “Holocaust denier” — as if questioning present policies and forecasts of the future is equivalent to casting malign doubt about a historical fact.

    [ : Climate change science is built on observations : all historical facts. Then, as in any valid science, a theoretical framework is applied to the data to check the theory – to make predictions of future change, and to validate them. It is an historical fact that the theoretical framework for global warming has not been falsified. The Earth system is warming – this cannot be denied. It seems to me that Nigel Lawwon usurps the truth with myth and unsubstantiated rumour, casting himself in the role of doubting dissenter, yet denying the evidence of the data. He therefore self-categorises as a denier, by the stance of denial that he takes. His denial is also an historical fact, but calling him a denier is not a value judgement. It is for each person to ascribe for themselves a moral value to the kind of denial he expresses. ]

    The heir to the throne and the minister are senior public figures, who watch their language. The abuse I received after appearing on the BBC’s Today programme last February was far less restrained. Both the BBC and I received an orchestrated barrage of complaints to the effect that it was an outrage that I was allowed to discuss the issue on the programme at all. And even the Science and Technology Committee of the House of Commons shamefully joined the chorus of those who seek to suppress debate.

    [ : Considering the general apathy of most television viewers, it is therefore quite refreshingly positive that so many people decided to complain about Nigel Lawson being given a platform to express his views about climate change, a subject about which it seems he is unqualified to speak with authority of learning. He may consider the complaints an “orchestrated barrage”. Another interpretation could be that the general mood of the audience ran counter to his contributions, and disagreed with the BBC’s decisiont to permit him to air his contrarian position, to the point of vexation. A parallel example could be the kind of outrage that could be expressed if Nigel Lawson were to deny that the Earth is approximately spherical, that gravity means that things actually move out to space rather than towards the ground, or that water is generally warmer than ice. He should expect opposition to his opinions if he is denying science. ]

    In fact, despite having written a thoroughly documented book about global warming more than five years ago, which happily became something of a bestseller, and having founded a think tank on the subject — the Global Warming Policy Foundation — the following year, and despite frequently being invited on Today to discuss economic issues, this was the first time I had ever been asked to discuss climate change. I strongly suspect it will also be the last time.

    The BBC received a well-organised deluge of complaints — some of them, inevitably, from those with a vested interest in renewable energy — accusing me, among other things, of being a geriatric retired politician and not a climate scientist, and so wholly unqualified to discuss the issue.

    [ : It is a mark of integrity to put you money where your mouth is, not an indicator on insincerity. It is natural to expect people who accept climate change science to be taking action on carbon dioxide emissions, which includes investment in renewable energy. ]

    Perhaps, in passing, I should address the frequent accusation from those who violently object to any challenge to any aspect of the prevailing climate change doctrine, that the Global Warming Policy Foundation’s non-disclosure of the names of our donors is proof that we are a thoroughly sinister organisation and a front for the fossil fuel industry.

    As I have pointed out on a number of occasions, the Foundation’s Board of Trustees decided, from the outset, that it would neither solicit nor accept any money from the energy industry or from anyone with a significant interest in the energy industry. And to those who are not-regrettably-prepared to accept my word, I would point out that among our trustees are a bishop of the Church of England, a former private secretary to the Queen, and a former head of the Civil Service. Anyone who imagines that we are all engaged in a conspiracy to lie is clearly in an advanced stage of paranoia.

    The reason why we do not reveal the names of our donors, who are private citizens of a philanthropic disposition, is in fact pretty obvious. Were we to do so, they, too, would be likely to be subject to the vilification and abuse I mentioned earlier. And that is something which, understandably, they can do without.

    That said, I must admit I am strongly tempted to agree that, since I am not a climate scientist, I should from now on remain silent on the subject — on the clear understanding, of course, that everyone else plays by the same rules. No more statements by Ed Davey, or indeed any other politician, including Ed Milliband, Lord Deben and Al Gore. Nothing more from the Prince of Wales, or from Lord Stern. What bliss!

    But of course this is not going to happen. Nor should it; for at bottom this is not a scientific issue. That is to say, the issue is not climate change but climate change alarmism, and the hugely damaging policies that are advocated, and in some cases put in place, in its name. And alarmism is a feature not of the physical world, which is what climate scientists study, but of human behaviour; the province, in other words, of economists, historians, sociologists, psychologists and — dare I say it — politicians.

    [ : Au contraire, I would say to Nigel Lawson. At root, climate change is very much a scientific issue. Science defines it, describes it and provides evidence for it. Climate change is an epistemological concern, and an ontological challenge. How we know what we know about climate change is by study of a very large number of results from data collection and other kinds of research. The evidence base is massive. The knowledge expressed in climate change science is empirical – based on observations – which is how we are sure that what we know is assured. There is still scope for uncertainty – will the surface temperatures rise by X plus or minus some Y, owing to the dynamic between the atmosphere, the oceans, the ice cover and the land masses ? The results of the IPCC assessments are that we pretty much know what X is, and we have an improved clarity on a range of values for Y. The more science is done, the clearer these numbers emerge. Knowledge increases as more science is done, which is why the IPCC assessments are making firmer conclusions as time passes. Climate change science does not make value judgements on its results. It concludes that sea levels are rising and will continue to rise; that rainfall patterns are changing and will continue to change; that temperatures are rising and will continue to rise under current economic conditions and the levels of fossil fuel use and land use. Science describes the outcomes of these and other climate changes. It is for us as human beings, with humanity in our hearts, to place a meaning on predicted outcomes such as crop and harvest failures, displacement of peoples, unliveable habitats, loss of plant and animal species, extreme weather. You cannot take the human out of the scientist. Of course scientists will experience alarm at the thought of these outcomes, just as the rest of society will do. The people should not be denied the right to feeling alarm. ]

    And en passant, the problem for dissenting politicians, and indeed for dissenting climate scientists for that matter, who certainly exist, is that dissent can be career-threatening. The advantage of being geriatric is that my career is behind me: there is nothing left to threaten.

    [ : Climate change science is not something you can “dissent” from if you are at all versed in it. For those who question any part of climate change science from inside the community of those who have appropriate knowledge and learning, their position is not one of dissent, but of being unable to assent completely to the conclusions of their peers. They lack a capacity to fully assent to the results of other people’s research because their own research indicates otherwise. As responsible members of the science community, they would then put their research conclusions and the research conclusions of others to the test. There is an integrity in this kind of questioning. It is a valid position, as long as the questions are posed in the language of scientific enquiry, and answered with scientific methods. For example, the Berkeley BEST team had questions about the evidence of global warming and set out to verify or falsify the results of others. Their own research led them to become convinced that their peers had been correct in the their conclusions. This is how science comes to consensus. Nigel Lawson should fund research in the field if he wishes to be taken seriously in denying the current consensus in climate change science. Instead of which, he invests in the publication of what appears to be uncorroborated hearsay and emotive politicking. ]

    But to return: the climate changes all the time, in different and unpredictable (certainly unpredicted) ways, and indeed often in different ways in different parts of the world. It always has done and no doubt it always will. The issue is whether that is a cause for alarm — and not just moderate alarm. According to the alarmists it is the greatest threat facing humankind today: far worse than any of the manifold evils we see around the globe which stem from what Pope called “man’s inhumanity to man”.

    [ : Nigel Lawson doesn’t need to tell anyone that weather is changeable and that climate changes. They can see it for themselves if they care to study the data. Climate change science has discovered that the current changes in the climate are unprecedented within at least the last 800,000 years. No previous period of rapid climate change in that era has been entirely similar to the changes we are experiencing today. This is definite cause for alarm, high level alarm, and not moderate. If there is a fire, it is natural to sound the alarm. If there is a pandemic, people spread the news. If there is a risk, as human beings, we take collective measures to avoid the threat. This is normal human precautionary behaviour. It is unreasonable for Nigel Lawson to insist that alarm is not an appropriate response to what is patently in the process of happening. ]

    Climate change alarmism is a belief system, and needs to be evaluated as such.

    [ : Belief in gravity, or thinking that protein is good to eat are also belief systems. Everything we accept as normal and true is part of our own belief system. For example, I believe that Nigel Lawson is misguided and has come to the wrong conclusions. The evidence lies before me. Is my opinion to be disregarded because I have a belief that Nigel Lawson is incorrect ? ]

    There is, indeed, an accepted scientific theory which I do not dispute and which, the alarmists claim, justifies their belief and their alarm.

    This is the so-called greenhouse effect: the fact that the earth’s atmosphere contains so-called greenhouse gases (of which water vapour is overwhelmingly the most important, but carbon dioxide is another) which, in effect, trap some of the heat we receive from the sun and prevent it from bouncing back into space.

    Without the greenhouse effect, the planet would be so cold as to be uninhabitable. But, by burning fossil fuels — coal, oil and gas — we are increasing the amount of carbon dioxide in the atmosphere and thus, other things being equal, increasing the earth’s temperature.

    But four questions immediately arise, all of which need to be addressed, coolly and rationally.

    First, other things being equal, how much can increased atmospheric CO2 be expected to warm the earth? (This is known to scientists as climate sensitivity, or sometimes the climate sensitivity of carbon.) This is highly uncertain, not least because clouds have an important role to play, and the science of clouds is little understood. Until recently, the majority opinion among climate scientists had been that clouds greatly amplify the basic greenhouse effect. But there is a significant minority, including some of the most eminent climate scientists, who strongly dispute this.

    [ : Simple gas chemistry and physics that is at least a century old is evidence that carbon dioxide allows sunlight to pass right through to warm the Earth, which then emits infrared light because it has warmed up. When the infrared radiation is emitted, the Earth cools down. Infrared is partially blocked by carbon dioxide, which absorbs it, then re-radiates it, partially back to the Earth, which warms up again. Eventually, the warming radiation will escape the carbon dioxide blanket, but because of this trapping effect, the net result is for more heat to remain in the atmosphere close to the Earth’s surface than you would expect. This is the main reason why the temperature of the Earth’s surface is warmer than space. As carbon dioxide accumulates in the atmosphere, the warming effect will be enhanced. This is global warming and it is undisputed by the overwhelming majority of scientists. Climate sensitivity, or Equilibrium Climate Sensitivity (ECS) is a calculated measure of the total temperature change that would be experienced (after some time) at the surface of the Earth for a doubling of atmospheric carbon dioxide concentrations compare to the pre-industrial age. The Transient Climate Response (TCR) is a measure of the temperature change that would be experienced in the shorter-term for a doubling of atmospheric carbon dioxide concentrations. The TCR can be easily calculated from basic physics. The shorter-term warming will cause climate change. Some of the changes will act to cool the Earth down from the TCR (negative feedbacks). Some of the changes will act to heat the Earth up from the TCR (positive feedbacks). These are some disagreements about the ECS, such as the net effects from the fertilisation effect of carbon dioxide on plant growth, the net effects of changes in weather and cloud systems, and the net effects of changes in ocean and atmospheric circulation. However, evidence from the deep past (paleoclimatology) is helping to determine the range of temperatures that ECS could be. ]

    Second, are other things equal, anyway? We know that, over millennia, the temperature of the earth has varied a great deal, long before the arrival of fossil fuels. To take only the past thousand years, a thousand years ago we were benefiting from the so-called medieval warm period, when temperatures are thought to have been at least as warm, if not warmer, than they are today. And during the Baroque era we were grimly suffering the cold of the so-called Little Ice Age, when the Thames frequently froze in winter and substantial ice fairs were held on it, which have been immortalised in contemporary prints.

    [ : The Medieval Warming Period (or Medieval Warm Period) was just a blip compared to the current global warming of the last 150 years. And the Little Ice Age was also a minor anomaly, being pretty much confined to the region of Europe, and some expect could have become the Rather Much Longer Icy Period had it not been for the use of fossil fuels, which warmed Europe up again. Burning coal and other fossil fuels releases carbon that would have originally been in the atmosphere in the form of carbon dioxide millions of years ago, that trees and other plants used to grow. Geological evidence shows that surface temperatures at those times were warmer than today. ]

    Third, even if the earth were to warm, so far from this necessarily being a cause for alarm, does it matter? It would, after all, be surprising if the planet were on a happy but precarious temperature knife-edge, from which any change in either direction would be a major disaster. In fact, we know that, if there were to be any future warming (and for the reasons already given, “if” is correct) there would be both benefits and what the economists call disbenefits. I shall discuss later where the balance might lie.

    [ : The evidence from the global warming that we have experienced so far since around 1880 is almost universally limiting in terms of the ability of species of animals and plants to survive. There are tiny gems of positive outcomes, compared to a sand pit of negatives. Yes, of course it matters. The mathematics of chaos with strong perturbations to any system do not permit it to coast on a precarious knife-edge for very long. Sooner or later there will be a major alteration, and the potential for some milder probable outcomes will collapse. ]

    And fourth, to the extent that there is a problem, what should we, calmly and rationally, do about it?

    [ : The most calm and rational thing to do is to compile all the evidence and report on it. Oh yes, we’ve already done that. It’s called the Intergovernmental Panel on Climate Change or IPCC. The concluisons of the compilation of over 100 years of science is that global warming is real, and it’s happening now, and that there is a wide range of evidence for climate change, and indicators that it is a major problem, and that we have caused it, through using fossil fuels and changing how we use land. ]

    It is probably best to take the first two questions together.

    According to the temperature records kept by the UK Met Office (and other series are much the same), over the past 150 years (that is, from the very beginnings of the Industrial Revolution), mean global temperature has increased by a little under a degree centigrade — according to the Met Office, 0.8ºC. This has happened in fits and starts, which are not fully understood. To begin with, to the extent that anyone noticed it, it was seen as a welcome and natural recovery from the rigours of the Little Ice Age. But the great bulk of it — 0.5ºC out of the 0.8ºC — occurred during the last quarter of the 20th century. It was then that global warming alarmism was born.

    [ : Nigel Lawson calls it “alarmism”. I call it empirical science. And there are many scientific explanations for what he calls “fits and starts”, it’s just that they’re written in research papers, so he will probably never read them, going on his lack of attention to research publications in the past. ]

    But since then, and wholly contrary to the expectations of the overwhelming majority of climate scientists, who confidently predicted that global warming would not merely continue but would accelerate, given the unprecedented growth of global carbon emissions, as China’s coal-based economy has grown by leaps and bounds, there has been no further warming at all. To be precise, the latest report of the Intergovernmental Panel on Climate Change (IPCC), a deeply flawed body whose non-scientist chairman is a committed climate alarmist, reckons that global warming has latterly been occurring at the rate of — wait for it — 0.05ºC per decade, plus or minus 0.1ºC. Their figures, not mine. In other words, the observed rate of warming is less than the margin of error.

    [ : It is not valid for Nigel Lawson to claim that there has been “no further warming at all”. Heat accumulation continues to be documented. Where is Nigel Lawson’s evidence to support his claim that the IPCC is a “deeply flawed body” ? Or is that another one of his entirely unsubstantiated dismissals of science ? Does he just fudge the facts, gloss over the details, pour scorn on scientists, impugn the academies of science, play with semantics, stir up antipathy, wave his hands and the whole history of science suddenly vanishes in a puff of dismissive smoke ? I doubt it ! Nigel Lawson says “the observed rate of warming is less than the margin of error.” This is ridiculous, because temperature is not something that you can add or subtract, like bags of sugar, or baskets of apples, or Pounds Sterling to the Global Warming Policy Foundation’s public relations fund. Two degrees Celsius, or Centigrade, is not twice as warm as one degree Celsius. 30 degrees C doesn’t indicate twice as much heat as 15 degrees C, or require twice as much heating. The range of figures that Nigel Lawson is quoting, minus 0.05 degrees C plus or minus 0.1 degrees C, that is, somewhere between a cooling of 0.05 degrees C and a warming of 0.15 degrees C, is a calculation of temperature trends averaged over the whole Earth’s surface for the last 15 years :- (Box 9.2)
    It is not surprising that over such a short timescale it might appear that the Earth as experienced a mild cooling effect. In the last 15 years there have been a couple of years far hotter than average, and these spike the calculated trend. For example, 1998 was much hotter than the years before or after it, so if you were just to compare 1998 with 2008, it would look like the Earth is cooling down. But who would be foolish enough to look at just two calendar years of the data record on which to base their argument ? The last 15 years have to be taken in context. In “Climate Change 2013 : The Physical Science Basis”, the IPCC report from Working Group 1, in the Summary for Policymakers, page 5, Section B1, the IPCC write :-
    “In addition to robust multi-decadal warming, global mean surface temperature exhibits substantial decadal and interannual variability […] Due to natural variability, trends based on short records are very sensitive to the beginning and end dates and do not in general reflect long-term climate trends. As one example, the rate of warming over the past 15 years (1998–2012; 0.05 [–0.05 to 0.15] °C per decade), which begins with a strong El Niño, is smaller than the rate calculated since 1951 (1951–2012; 0.12 [0.08 to 0.14] °C per decade).” (El Niño is a prominent pattern of winds and ocean currents in the Pacific Ocean with two main states – one that tends to produce a warming effect on the Earth’s surface temperatures, and the other, La Niña, which has a general cooling effect.) ] In other words, in the last fifteen years, the range of rate of change of temperature is calculated to be somewhere between the surface of the planet cooling by 0.05 degrees Centigrade, up to warming by 0.15 degrees Centigrade :-
    However, this calculation of a trend line does not take account of three things. First, in the last decade or so, the variability of individual years could mask a trend, but relative to the last 50 years, everything is clearly hotter on average. Secondly, temperature is not a “discrete” quantity, it is a continuous field of effect, and it is going to have different values depending on location and time. The temperature for any January to December is only going to be an average of averages. If you were to measure the year from March to February instead, the average of averages could look different, because of the natural variability. Thirdly, there are lots of causes for local and regional temperature variability, all concurrent, so it is not until some time after a set of measurements has been taken, and other sets of measurements have been done, that it is possible to determine that a substantial change has taken place. ]

    And that margin of error, it must be said, is implausibly small. After all, calculating mean global temperature from the records of weather stations and maritime observations around the world, of varying quality, is a pretty heroic task in the first place. Not to mention the fact that there is a considerable difference between daytime and night-time temperatures. In any event, to produce a figure accurate to hundredths of a degree is palpably absurd.

    [ : Nigel Lawson could be said to mislead in his explanation of what “a figure accurate to hundredths of a degree” implies. Temperature is measured on an arbitrarily decided scale. To raise the whole of the Earth surface temperatures by 1 degree Celsius requires a lot of extra trapped energy. The surface temperature of the Earth is increasing by the absorption of energy that amounts roughly to 2 trillion Hiroshima atombic bombs since 1998, or 4 Hiroshimas a second. That is not a small number, although it has to be seen in the full context of the energy flows in and out of the Earth system :-
    Nigel Lawson credits the global temperature monitoring exercise as “heroic”, but then berates its quality. However, climate change scientists do already appreciate that there are differences between daytime and nighttime temperatures – it is called the diurnal range. Besides differences between years, it is known that there are also differences between seasons, and latitudes, and climatic zones. Scientists are not claiming an absolute single value for the temperature of the Earth, accurate to within hundredths of a degree – that’s why they always give a margin of error. What is astonishing from reviews of the data is something that Nigel Lawson has completely missed. Global warming appears to have fractal resolution – that is – at whatever geographical scale you resolve the data, the trend in most cases appears to be similar. If you take a look at some of the websites offering graphs, for example :-
    the global warming trend is seen to be generally similar when averaged locally, regionally or at the global scale. This is an indicator that the global warming signal is properly being detected, as these trend lines are more or less what you would expect from basic physics and chemistry – the more carbon dioxide in the air, the more heat gets trapped, and the rate of carbon dioxide accumulation in the atmosphere has seen similar trendlines :- ]

    The lessons of the unpredicted 15-year global temperature standstill (or hiatus as the IPCC calls it) are clear. In the first place, the so-called Integrated Assessment Models which the climate science community uses to predict the global temperature increase which is likely to occur over the next 100 years are almost certainly mistaken, in that climate sensitivity is almost certainly significantly less than they once thought, and thus the models exaggerate the likely temperature rise over the next hundred years.

    [ : I repeat : there is no pause. The IPCC are not claiming that global warming has stopped, only that there is an apparent “hiatus” in global surface temperature averages. Some scientists have concluded from their work that Climate Sensitivity is less than once feared. However, Climate Sensitivity is calculated for an immediate, once-only doubling of carbon dioxide in the atmosphere, whereas the reality is that carbon dioxide is continuing to build up in the atmosphere, and if emissions continue unabated, there could be a tripling or quadrupling of carbon dioxide concentrations in the atmosphere, which would mean that you would need to multiply the Climate Sensitivity by 1.5 or 2 to arrive at the final top temperature – higher than previously calculated, regardless of whether the expected Climate Sensitivity were to be less than previously calculated. It is therefore illogical for Nigel Lawson to extrapolate from his understanding that Climate Sensitivity is lower than previously calculated to his conclusion that the final level of global warming will be lower than previously calculated. The more carbon dioxide we emit, the worse it will be. ]

    But the need for a rethink does not stop there. As the noted climate scientist Professor Judith Curry, chair of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology, recently observed in written testimony to the US Senate:
    “Anthropogenic global warming is a proposed theory whose basic mechnism is well understood, but whose magnitude is highly uncertain. The growing evidence that climate models are too sensitive to CO2 has implications for the attribution of late-20th-century warming and projections of 21st-century climate. If the recent warming hiatus is caused by natural variability, then this raises the question as to what extent the warming between 1975 and 2000 can also be explained by natural climate variability.”

    [ : The IPCC reports constitute the world’s best attempts to “rethink” Climate Change. Professor Judith Curry, in the quotation given by Nigel Lawson, undervalues a great deal of her colleagues’ work by dismissing their valid attribution of Climate Change to the burning of fossil fuels and the change in land use. ]

    It is true that most members of the climate science establishment are reluctant to accept this, and argue that the missing heat has for the time being gone into the (very cold) ocean depths, only to be released later. This is, however, highly conjectural. Assessing the mean global temperature of the ocean depths is — unsurprisingly — even less reliable, by a long way, than the surface temperature record. And in any event most scientists reckon that it will take thousands of years for this “missing heat” to be released to the surface.

    [ : That the oceans are warming is not conjecture – it is a statement based on data. The oceans have a far greater capacity for heat retention than the atmosphere, so yes, it will take a long time for heat in the oceans to re-emerge into the atmosphere. However, the processes that directed heat into the oceans rather than the atmosphere in recent years could easily reverse, and in a short space of time the atmosphere could heat up considerably. In making his arguments, Nigel Lawson omits to consider this eventuality, which lowers considerably the value of his conclusions. ]

    In short, the CO2 effect on the earth’s temperature is probably less than was previously thought, and other things — that is, natural variability and possibly solar influences — are relatively more significant than has hitherto been assumed.

    [ : Nothing about science has changed. The Earth system continues to accumulate heat and respond to that. Carbon dioxide still contributes to the Greenhouse Effect, and extra carbon dioxide in the air will cause further global warming. The Transient Climate Response to carbon dioxide is still apparently linear. The Equilibrium Climate Sensitivity is still calculated to be roughly what it always has been – but that’s only for a doubling of atmospheric carbon dioxide. If more methane is emitted as a result of Arctic warming, for example, or the rate of fossil fuel use increases, then the temperature increase of the Earth’s surface could be more than previously thought. Natural variability and solar changes are all considered in the IPCC reports, and all calculations and models take account of them. However, the obvious possibility presents itself – that the patterns of natural variability as experienced by the Earth during the last 800,000 years are themseles being changed. If Climate Change is happening so quickly as to affect natural variability, then the outcomes could be much more serious than anticipated. ]

    But let us assume that the global temperature hiatus does, at some point, come to an end, and a modest degree of global warming resumes. How much does this matter?

    The answer must be that it matters very little. There are plainly both advantages and disadvantages from a warmer temperature, and these will vary from region to region depending to some extent on the existing temperature in the region concerned. And it is helpful in this context that the climate scientists believe that the global warming they expect from increased atmospheric CO2 will be greatest in the cold polar regions and least in the warm tropical regions, and will be greater at night than in the day, and greater in winter than in summer. Be that as it may, studies have clearly shown that, overall, the warming that the climate models are now predicting for most of this century (I referred to these models earlier, and will come back to them later) is likely to do more good than harm.

    [ : The claim that warming will “overall […] do more good than harm” is erroneous, according to Climate Change Science. ]

    Global warming orthodoxy is not merely irrational. It is wicked.

    [ : My conclusions upon reading this lecture are that the evidence suggests that Nigel Lawson’s position is ill-informed. He should read the IPCC reports and re-consider. ]

  • David MacKay : Heating London

    Posted on May 2nd, 2014 Jo No comments

    I took some notes from remarks made by Professor David MacKay, the UK Government’s Chief Scientific Advisor, yesterday, 1st May 2014, at an event entitled “How Will We Heat London ?”, held by Max Fordhams as part of the Green Sky Thinking, Open City week. I don’t claim to have recorded his words perfectly, but I hope I’ve captured the gist.

    [David MacKay] : [Agreeing with others on the panel – energy] demand reduction is really important. [We have to compensate for the] “rebound effect”, though [where people start spending money on new energy services if they reduce their demand for their current energy services].

    SAP is an inaccurate tool and not suitable for the uses we put it too :-

    Things seem to be under-performing [for example, Combined Heat and Power and District Heating schemes]. It would be great to have data. A need for engineering expertise to get in.

    I’m not a Chartered Engineer, but I’m able to talk to engineers. I know a kilowatt from a kilowatt hour [ (Laughter from the room) ]. We’ve [squeezed] a number of engineers into DECC [the Department of Energy and Climate Change].

    I’m an advocate of Heat Pumps, but the data [we have received from demonstration projects] didn’t look very good. We hired two engineers and asked them to do the forensic analysis. The heat pumps were fine, but the systems were being wrongly installed or used.

    Now we have a Heat Network team in DECC – led by an engineer. We’ve published a Heat Strategy. I got to write the first three pages and included an exergy graph.

    [I say to colleagues] please don’t confuse electricity with energy – heat is different. We need not just a green fluffy solution, not just roll out CHP [Combined Heat and Power] [without guidance on design and operation].

    Sources of optimism ? Hopefully some of the examples will be available – but they’re not in the shop at the moment.

    For example, the SunUp Heat Battery – works by having a series of chambers of Phase Change Materials, about the size of a fridge that you would use to store heat, made by electricity during the day, for use at night, and meet the demand of one home. [Comment from Paul Clegg, Senior Partner at Feilden Clegg Bradley Studios : I first heard about Phase Change Materials back in the 1940s ? 1950s ? And nothing’s come of it yet. ] Why is that a good idea ? Well, if you have a heat pump and a good control system, you can use electricity when it’s cheapest… This is being trialled in 10 homes.

    Micro-CHP – [of those already trialled] definitely some are hopeless, with low temperature and low electricity production they are just glorified boilers with a figleaf of power.

    Maybe Fuel Cells are going to deliver – power at 50% efficiency [of conversion] – maybe we’ll see a Fuel Cell Micro-Combined Heat and Power unit ?

    Maybe there will be hybrid systems – like the combination of a heat pump and a gas boiler – with suitable controls could lop off peaks of demand (both in power and gas).

    We have designed the 2050 Pathways Calculator as a tool in DECC. It was to see how to meet the Carbon Budget. You can use it as an energy security calculator if you want. We have helped China, Korea and others to write their own calculators.

    A lot of people think CHP is green and fluffy as it is decentralised, but if you’re using Natural Gas, that’s still a Fossil Fuel. If you want to run CHP on biomass, you will need laaaaaarge amounts of land. You can’t make it all add up with CHP. You would need many Wales’-worth of bioenergy or similar ways to make it work.

    Maybe we should carry on using boilers and power with low carbon gas – perhaps with electrolysis [A “yay !” from the audience. Well, me, actually]. Hydrogen – the the 2050 Calculator there is no way to put it back into the beginning of the diagram – but it could provide low carbon heat, industry and transport. At the moment we can only put Hydrogen into Transport [in the 2050 Calculator. If we had staff in DECC to do that… It’s Open Source, so if any of you would like to volunteer…

    Plan A of DECC was to convert the UK to using lots of electricity [from nuclear power and other low carbon technologies, to move to a low carbon economy], using heat pumps at the consumer end, but there’s a problem in winter [Bill Watts of Max Fordham had already shown a National Grid or Ofgem chart of electricity demand and gas demand over the year, day by day. Electricity demand (in blue) fluctuates a little, but it pretty regular over the year. Gas demand (in red) however, fluctuates a lot, and is perhaps 6 to 10 times larger in winter than in summer.]

    If [you abandon Plan A – “electrification of everything”] and do it the other way, you will need a large amount of Hydrogen, and a large Hydrogen store. Electrolysers are expensive, but we are doing/have done a feasibility study with ITM Power – to show the cost of electrolysers versus the cost of your wind turbines [My comment : but you’re going to need your wind turbines to run your electrolysers with their “spare” or “curtailed” kilowatt hours.]

    [David Mackay, in questions from the floor] We can glue together [some elements]. Maybe the coming smart controls will help…can help save a load of energy. PassivSystems – control such things as your return temperature [in your Communal or District Heating]…instead of suing your heat provider [a reference to James Gallagher who has problems with his communal heating system at Parkside SE10], maybe you could use smart controls…

    [Question] Isn’t using smart controls like putting a Pirelli tyre on a Ford Cortina ? Legacy of poor CHP/DH systems…

    [David MacKay in response to the question of insulation] If insulation were enormously expensve, we wouldn’t have to be so enthusastic about it…We need a well-targeted research programme looking at deep retrofitting, instead of letting it all [heat] out.

    [Adrian Gault, Committee on Climate Change] We need an effective Government programme to deliver that. Don’t have it in the Green Deal. We did have it [in the previous programmes of CERT and CESP], but since they were cancelled in favour of the Green Deal, it’s gone off a cliff [levels of insulation installations]. We would like to see an initiative on low cost insulation expanded. The Green Deal is not producing a response.

    [Bill Watts, Max Fordham] Agree that energy efficiency won’t run on its own. But it’s difficult to do. Not talking about automatons/automation. Need a lot of pressure on this.

    [Adrian Gault] Maybe a street-by-street approach…

    [Michael Trousdell, Arup] Maybe a rule like you can’t sell a house unless you’ve had the insulation done…

    [Peter Clegg] … We can do heat recovery – scavenging the heat from power stations, but we must also de-carbonise the energy supply – this is a key part of the jigsaw.

    John and Jono: Resistance to coal in heat-afflicted Australia
    By Miriam Pepper, 24/1/13

    It was predicted to be a hot summer in eastern Australia, with a return to dry El Nino conditions after two back-to-back wet La Nina years. And hot it has been indeed. Temperature records have tumbled across the country – including the hottest day, the longest heatwave, and the hottest four month period.

    With heavy fuel loads heightening fire risks, bushfires have blazed across Tasmania, Victoria, NSW, South Australia and Queensland. The fires have wreaked devastation on communities, with homes, farmland and forest destroyed. Thankfully few human lives have been lost (unlike the Black Saturday bushfires of 2009), though many non-human neighbours were not so fortunate. Some 110,000 hectares burned and 130 houses were lost in the Tasmanian bushfires earlier this month, and fires still rage in Gippsland Victoria where over 60,000 hectares have burned so far. And we are only just over halfway through summer.

    On January 12, the Australian Government-established Climate Commission released a short report entitled “Off the charts: Extreme Australian Summer heat”. The document concluded that:

    “The length, extent and severity of this heatwave are unprecedented in the measurement record. Although Australia has always had heatwaves, hot days and bushfires, climate change has increased the risk of more intense heatwaves and extreme hot days, as well as exacerbated bushfire conditions. Scientists have concluded that climate change is making extreme hot days, heatwaves and bushfire weather worse.”

    The Australian continent is one of climate change’s frontlines, and also a major source of its primary cause – fossil fuels.

    While the mercury soared and the fires roared, a young translator from Newcastle called Jonathan Moylan issued a fake press release claiming that the ANZ bank, which is bankrolling a massive new coal project at Maules Creek in north western NSW, had withdrawn its loan. Whitehaven Coal’s share price plummeted temporarily before the hoax was uncovered, making national news.

    This action did not come out of the blue, neither for Moylan personally nor for the various communities and groups that have for years been confronting (and been confronted by) the rapid expansion of coal and coal seam gas mining at sites across Australia.

    The scale of fossil fuel expansion in Australia is astonishing. Already the world’s biggest coal exporter, planned mine expansion could see Australia double its output. The world’s largest coal port of Newcastle NSW has already doubled its capacity in the last 15 years and may now double it again. Mega-mines that are on the cards in the Galilee Basin in central Queensland would quintuple ship movements across the Great Barrier Reef, to 10,000 coal ships per year. If the proposed Galilee Basin mines were fully developed today, the annual carbon dioxide emissions caused by burning their coal alone would exceed those of the United Kingdom or of Canada. The implications of such unfettered expansion locally for farmland, forests, human health and aquatic life as well as globally for the climate are severe.

    I have twice had the privilege of participating in a Christian affinity group with Moylan at coal protests. And at around the time of his ANZ stunt, John the Baptist’s ministry and the baptism of Jesus in the gospel of Luke were on the lectionary. For me, there have been some striking parallels between John and Jonathan (Jono).

    John the Baptist lived in the wilderness. Jono the Activist has been camping for some time in Leard State Forest near Maules Creek, at a Front Line Action on Coal mine blockade.

    John got himself locked up by criticising the behavior of Herod, the then ruler of Galilee (in what is now northern Israel). For making the announcement that ANZ should have made, Jono could now face a potential 10-year jail sentence or a fine of up to $500,000.

    When followers suggested that John the Baptist might be the Messiah, he pointed away from himself and towards the Christ that was yet to come. When the spotlight has been shone onto Moylan, by the media and activists alike, he has repeatedly deflected the attention away from himself and towards the resistance of the Maules Creek community to the project and towards the impacts if the project goes ahead – the loss of farmland and critically endangered forest, the drawdown and potential contamination of the aquifer, the coal dust, the impacts on the global climate. And indeed, the way that Moylan has conducted himself in media interviews has I believe resulted in exposure about the Maules Creek project itself (which is currently under review by the federal Environment Minister) as well as some mainstream discussion about broader issues such as responding to the urgency of climate change, government planning laws and the rights of communities, and ethical investment.

    In an opinion piece published today, Jono Moylan finishes by urging us to act:

    “We are living in a dream world if we think that politicians and the business world are going to sort out the problem of coal expansion on their own. History shows us that when power relations are unevenly matched, change always comes from below. Every right we have has come from ordinary people doing extraordinary things and the time to act is rapidly running out.”

    Whatever our age, ability or infirmity we can all play a part in such change from below.

  • 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.

    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 ?

  • 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 !

  • Rooftop Solar : Summer Highs

    Posted on November 7th, 2011 Jo 1 comment

    Image Credit : Intelligence Squared

    George Monbiot is right about a lot of things, but on rooftop solar power, I believe he is wrong.

    Yes, he’s right that solar photovoltaic systems are being incentivised more than other micro-generation, but there are several good reasons for that. For a first, the unit price of an adequate rooftop solar power system is in the region of the price of a car.

    Most people use finance schemes to purchase cars, with monthly charges for example.

    Similar schemes are not available for solar PV, where you have to borrow the whole amount for the system up-front – or take it from a savings account if you’re lucky enough to have one.

    It is the sheer size of the cost of home solar that means that people won’t do it without subsidy. The one overriding concern of people when I ask them about what green energy they could consider buying, is the size of the initial outgoings.

    James Delingpole hardly ever sets his delicate foot in Wales, the country he archaically refers to as “the Principality”, apart from, ooh, about ten days a year when he holidays there, but nonetheless, feels he has some kind of inherited ex-colonial right to be affronted that large electricity generation and transmission infrastructure are going to be built there :-

    He gets top marks for being rather offensive himself – achingly rude, in fact, about the Welsh Assembly, besides his getting untethered about the wind farms and pylons for the transmission cables :-

    “…The wind farms are bad enough on their own. But to make matters far worse […], in order for these bird-crunching, bat-chomping, view-blighting, rent-seeking monstrosities to be connected to the grid a huge 400kv power line is going to be constructed all the way from Montgomeryshire through some of Britain’s most spectacular scenery to the equally beauteous Shropshire…”

  • 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 ?

  • Cool poverty

    Posted on April 21st, 2011 Jo No comments

    They’ve never had it so cold. The British have just shivered through another long, centrally heated winter, and people are receiving enormous gas bills. Social campaigners and parliamentarians are rightly concerned that a clutch of harsher winters and rising energy costs could reverse gains made in tackling fuel poverty. The UK Government’s recent Budget announcement to reduce fuel poverty assistance payments is another blow to maintaining decent and warm homes for the vulnerable, the elderly and children. Proposals to cap the amount that energy companies can charge people in their bills is welcomed by some, but feared by others – as it could jeopardise energy company funding for the Green Deal – a free-to-the-consumer loan scheme for insulation and renewable energy installation. And there’s another problem waiting in the wings. Unlike the United States and Australia, the average British home doesn’t have air conditioning, and it costs real money to install it. If outsized summer heatwaves continue to pop up more frequently in Europe, UK households will face “cool poverty” in summer – a lack of cooling.

  • This Is What Overwarming Looks Like

    Posted on September 17th, 2010 Jo No comments

    “We have to believe what we are witnessing with our own eyes — floods, fires, melting ice and feverish heat: from smoke-choked Moscow to water-soaked Pakistan, to soaring temperatures in the US and a deteriorating landscape in the High Arctic, our planet seems to be having a breakdown. It’s not just a portent of things to come but real signs of very troubling climate change already under way.”

    “Tell Congress not to weaken Clean Air Act protections : As the EPA prepares to set standards for global warming pollution from power plants, refineries and other major polluters, some members of Congress want to weaken the Clean Air Act and give industries free rein to dump harmful pollution into our air…”

    “With January to August 2010 found to be tied for the hottest year on record by NOAA, new analysis from NRDC shows that it wasn’t just daytime temperatures that’ve been soaring. In fact, 37 states in the US set record high nighttime temperatures this summer…”

    The British Government is about to announce that the people be left to the ravages of Climate Change and cope by heaving-ho and a rolling-up of the sleeves and display war-time grittedness through voluntary “Big Society” :-

    “Britain must adapt to ‘inevitable’ climate change, warns minister : As experts call for action now, the coalition withholds green funding and appeals to private enterprise : By Matt Chorley and Jonathan Owen : Sunday, 12 September 2010 : Britons must radically change the way they live and work to adapt to being “stuck with unavoidable climate change” the Government will caution this week, as it unveils a dramatic vision of how society will be altered by floods, droughts and rising temperatures. The coalition will signal a major switch towards adapting to the impact of existing climate change, away from Labour’s heavy emphasis on cutting carbon emissions to reverse global temperature rises. Caroline Spelman, the Tory Secretary of State for the Environment, will use her first major speech on climate change since taking office to admit that the inevitable severe weather conditions will present a “survival-of-the- fittest scenario”, with only those who have planned ahead able to thrive. Adapting to climate change will be “at the heart of our agenda”, she is expected to say…”

    “Climate change is inevitable, says Caroline Spelman : Britain can no longer stop global warming and must instead focus on adapting to the ‘inevitable’ impacts of climate change such as floods, droughts and rising sea levels, Government ministers will warn this week. : By Louise Gray, Environment Correspondent : Published : 13 Sep 2010 : For the past few years Government policy has concentrated on trying to make people turn off lights and grow their own vegetables in an effort to bring down carbon emissions. But as global greenhouse gases continue to increase, with the growth of developing countries like China and India, and the public purse tightens, the focus will increasingly be on adapting to climate change. The Government will set out plans to protect power stations from flooding and ensure hospitals can cope with water shortages during dry summers….”

  • Let Others Move First

    Posted on August 19th, 2010 Jo No comments

    Nick Clegg, the British Deputy Prime Minister says that the international response to the catastrophic flooding in Pakistan is “absolutely pitiful” :-

    People won’t be moved. There’s no use hoping for an outpouring of charitable giving and energetic aid organisation – the world is suffering too many ongoing parallel disasters to be able to scramble effectively for this – the biggest ever (probably).

    A similar situation exists with Climate Change policy, or rather the incredible inertia against taking the obvious first steps towards meaningful Carbon Dioxide emissions reductions.

    People are too busy with their Facebook, their Twitter, their own personal financial nemeses (is that the plural of “nemesis”, really ?) to be able to form a coherent “movement”, as Bill McKibben, Al Gore and others wish us to mobilise into :-

    “Why has extreme weather failed to heat up climate debate? The world is experiencing the hottest weather on record but politicians have failed to respond. They need a wake-up call…”

    [ YouTube Credit : The link to the video above comes thanks to the endeavours of that most fair and balanced individual James “no net global warming since 1998” Delingpole. “No net global warming since 1998” ? James ! You’re quoting Pat Michaels, but did he perhaps make that up ? Or was it something that Christopher Monckton might have made up ? ]

    The BBC puts the blame on Climate Change – almost – in a report on the Russian heatwave-wildfire disaster.

    But they just can’t bring themselves to admit it as an organisation – and put the claims into the mouths of others – using quotation marks in the headline (‘partly to blame’) and ascribing the opinion to “researchers”, the “UK Met Office” and “experts” :-

    “10 August 2010 : Climate change ‘partly to blame’ for sweltering Moscow : By Katia Moskvitch : Science reporter, BBC News : Global climate change is partly to blame for the abnormally hot and dry weather in Moscow, cloaked in a haze of smoke from wildfires, say researchers. The UK Met Office said there are likely to be more extreme high temperatures in the future. Experts from the environmental group WWF Russia have also linked climate change and hot weather to raging wildfires around the Russian capital. Meteorologists say severe conditions may linger for several more days…”

    Well, I’ve got a bit of a question to pose – it might not be possible to ascribe the current weather conditions in Russia (and Pakistan and China and and and…) to Climate Change, statistically. I mean no one weather event can be said to have been caused 100% by Climate Change. But would these extreme weather events have happened without Climate Change ?

    That is by far the most important question to ask, and Michael Tobis does just that :-

    “…Are the current events in Russia “because of” “global warming”? To put the question in slightly more formal terms, are we now looking at something that is no longer a “loading the dice” situation but is a “this would, practically certainly, not have happened without human interference” situation? Can we phrase it more formally? “Is the average time between persistent anomalies on this scale anywhere on earth in the undisturbed holocene climate much greater than a human lifetime?” In other words, is this so weird we would NEVER expect to see it at all?…”
