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.

We’ve both been out, enjoying “Tee-Shirt Thursday”, a day of warming, bright sunshine and Spring-like temperatures – in the middle of Winter.

“What about Eastern Europe ?”, he asked, “They’ve had incredibly cold and snowy weather.” “I know. You get these cold snaps”, I agreed, “Hundreds of people have died. But this is what you should expect with climate change, all the normal weather patterns have been disturbed.”

“It’s not a snap”, Mick said, “it’s been going on for weeks.” “Yes”, I said, “these areas of high and low temperatures have been locking into place. It’s all because of global warming.”

“But there hasn’t been any global warming for fifteen years”, said Mick. “Which newspaper do you read ?” I asked him, taken aback. “I don’t read any newspapers”, he clarified, “I read it in the library, somewhere.”

The GWPF believes it has made a difference, saying of itself “The key to the success of the GWPF is the trust and credibility that we have earned in the eyes of a growing number of policy makers, journalists and the interested public.” Yet the GWPF has also been criticised for being secretive, misinformed, wrong and perverse.

Yesterday evening, I decided to catch up on exactly how out of control atmospheric methane concentrations are in the region around the Arctic :-

http://www.esrl.noaa.gov

When reviewing the charts, the secondmost important thing to see is the high point measurements, the peaks, rising over time.

Much of this methane explosion can probably be blamed on global warming from excessive carbon dioxide emissions – which showed signs of coming under control between 1990 and 2000, but after that lifted off once more.

People dispute why carbon dioxide emissions have risen consistently and sharply since the turn of the millenium – but one of the answers is to be found in the rapid deployment of coal-burning for power generation. Stronger environmental controls on air quality have reduced the health impacts of coal-burning, but mean that the net effect is stronger global warming.

So much could be done to alleviate the strong warming of the Arctic, and prevent dangerous instabilities. It is time to say it – and keep on saying it – and not relent – every measure to keep the Arctic cool is urgent.

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.

“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.”

The Climate Change talks that have just taken place in Durban, South Africa, were exemplary of a peculiar kind of collective madness that has resulted from trying to navigate and massage endless special interests, national jostling, brinkmanship, unworkable and inappropriate proposals from economists, communications failures and corporate interference in governance.

The right people with real decisionmaking powers are not at the negotiating table. The organisations with most to contribute are still acting in opposition – that’s the energy industry, to be explicit. And the individual national governments are still not concerned enough about climate change, even though it impacts strongly on the things they do consider to be priorities – economic health, trade and political superiority.

Over 20 years ago, the debate on what to do to tackle global warming and still maintain good international relations was already won, by the commonsense approach of Contraction and Convergence – fair shares for all. Each country should count on their fair share of carbon emissions based on their population – and we would get there by starting from where we are now and agreeing mutual cuts. The big emitters would agree to steeper cuts than the lower emitters – and after some time, everybody in the world would have the same, safe emissions rights.

What has prevented this logical approach from being implemented ? Well, we have had the so-called “flexible mechanisms” pushed on us – such as the Clean Development Mechanism which essentially boils down to the idea that the richer high-emitting countries can offset their carbon by paying for poorer low emissions countries to cut their carbon instead. Some have been attempting to make the CDM carbon credits into a commercial product for the Carbon Trading market. Some may contest it, but the CDM and carbon trading haven’t really been working very well, and anyway, the CDM doesn’t aim for emissions reductions, just offsets.

Other carbon trade has been implemented, such as the European Union Emissions Trading Scheme (EU ETS), which doesn’t appear to have caused high emissions industries to diversify out of carbon, or created a viable price for carbon dioxide, so its usefulness is questionable.

Many people have put forward the idea of straight carbon pricing, mostly by taxation. The trouble with this idea should be obvious, but rarely is. Over four-fifths of the world’s energy is fossil fuel based. Taxing carbon emissions from the burning of fossil fuels would just make everything, everywhere, more expensive. It wouldn’t necessarily create new lower carbon energy resources, as the taxes would probably be put into a giant climate change adaptation fund – a financial institution proposed by several people including Oliver Tickell and Nicholas Stern, although in Stern’s case, he is calling for direct grants from countries to keep the fund topped up.

On the policy front, there has been a continuing, futile attempt to force the historially high-emitting countries to accept very radical carbon cuts, as a sign of accountability. This “grandfathering” of emissions responsibilities is something that no sane person in government in the richer nations could ever agree with, not even when being smothered with ethical guilt. One of the forms of this proposal is “Greenhouse Development Rights“, essentially allowing countries like China to continue growing their emissions in order to grow their economies to guarantee development. The emissions cuts required by countries like the United States of America would be impossible to achieve, not even if their economy completely toppled.

Sadly, a number of charities, aid and development agencies and other non-governmental organisations with concern for the world’s poor, have signed up to Greenhouse Development Rights not realising it is completely untenable.

The only approach that can work, that both high- and low-emitting countries can ever possibly be made to agree on, is a system of population-proportional shares of the global carbon pie. And the way to get there has to be based on relative current emissions, ignoring the emissions of the past – your cuts should be larger if your current emissions are large. And it should be based on the relative size of the population, and their individual emissions rates, rather than taking a country as a whole. Yes, there will be room for a little carbon trade between nations, to enable the transfer of low carbon technologies from wealthy nations to un-resourced nations. Yes, there will be space for enterprise, as corporations have to face regulation to cut emissions, and will need innovation in technology to divest themselves of fossil fuel production and consumption.

This is Contraction and Convergence – and you ignore it at our peril.

The second human brain is a relativistic engine, constantly comparing, reflecting, analysing. We are concerned about other peoples’ emotional response, wondering what other people think about us, responding to peer group pressure.

Personally, I don’t listen to my second brain very often. As a social animal, I hope I’m tolerant, and my priorities in interpersonal engagement are mutual empowerment, transparent collaboration and inclusion. In my public projection, I’m not trying to vaunt myself over others, or massage my image for approval, or put up a fake facade. You get me, you get direct.

But I can’t avoid the second human brain entirely – as it is the reason for a lot of fuzziness in our view of the world around us. It’s too easy to stir doubt, falsehoods and bad ideas into the collective cake mix of society, where it fizzes into a bubbling mess. In matters of climate change science and energy engineering, there are no grey areas for me. But for a number of people I know, these are subjects of much confusion, denial and disinformation.

People hold on to the totem of what other people think. And so you have even very intelligent social commentators reciting from paid-for public relations by companies and business pressure groups. Journalists often do not appear to understand the difference between pseudo-science and real live science. There are too many people selling unrealistic, unworkable technological “solutions”, particularly in energy, so it’s hard to know what to accept and what to dismiss.

Yet it is critical to know what rock, what branch to keep a hold of in the flood of information that could sweep us away. The social construction of climate change is an important edifice, a safe house in an information world at war with itself. What high wind can sweep away the grubby pages of non-science from the Daily Mail ? What rising sea can cleanse the Daily Telegraph of its climate change denial columnists ? What can stop the so-called Global Warming Policy Foundation from infecting the Internet with their contrarian position ? What can make us accept the reality and urgency of global warming ? How can we learn to click with climate change ?

Three significant academic thinkers on the social significance of climate change are launching new works at the British Library in London, on 16th January 2012. The British Sociological Association have invited Mike Hulme, John Urry and Gordon Walker to discuss chapters from their recent books which address the question – where next for society and climate change ?

In the words of Chris Shaw at the University of Sussex, “they pull no punches in their analyses, and their approach is based on years of research into the social dimensions of the climate change debate. This is an essential opportunity for all those interested in bringing climate change into the democratic sphere, to help understand the issues involved in such a transition. It is also a chance to discuss the ideas with the authors and other delegates.”

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.

Dear XXXXXXXXXXX,

It seems to me that you are labouring under several false impressions of the consensus in science regarding global warming and climate change. For example, you do not appear to accept that global warming is taking place, a fact that is evidenced by over a century of data. And as another example, you do not appear to accept that global warming is causing climate change, a scientific reality evidenced by countless studies. However, I’m not going to guide you to the peer-reviewed science for those points. All I want to do in this particular communication is offer you a popular critique of one of your key arguments, and challenge you to check your sources.

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.

Detecting that I was speaking with a native French-speaker, I slipped into my rather unpracticed second language to explain that I could not countenance working with the militaries, because I disagree with their strategy of repeated aggression.

Whoops, there goes another great opportunity to make a huge pile of cash, contracting for warmongers ! Sometimes you just have to kiss a career goodbye. IT consultancy has many ethical pitfalls. Time to reinvent myself.

I’ve been “back to school” for the second university degree, and now I’m supposed to submit myself to the “third degree” – go out and get me a job. The paucity of available positions due to the poor economic climate notwithstanding, the possibility of ending up in an unsuitable role fills me with dread. One of these days I might try to write about my experiences of having to endure several kinds of abuse whilst engaged in paid employment : suffice it to say, workplace inhumanity can be unbearable, some people don’t know what ethical behaviour means, and Human Resources departments always take sides, especially with vindictive, manipulative, micro-managers. I know what it’s like to be powerless.
