Climate Technocrats at Durban

I have a story up on Spiked today…

It was the latest in a long series of last chances to save the planet. Like a convention of superheroes, 14,500 politicians, civil servants, journalists and campaigners from development and environmental NGOs descended on Durban, South Africa, for the seventeenth Committee of Parties (COP) meetings under the United Nations Framework Convention on Climate Change (UNFCCC). Their agreement, if they could reach one, would save the remaining 6,999,985,500 of us from certain doom.

I’m so bored… BORED… of climate change. Environmentalism is such a boring, boring, boring thing. It’s mundane. It’s banal. It obsesses about the minutiae of biological functioning only to the extent that it wants to limit the possibilities of human life, rather than extend them. And it is mean spirited — it nags you about whether children need those Christmas presents, if you need that holiday, if you really need to take the car. It’s a joyless, nihilistic chasm, which sucks the life out of life.

According to some definitions, ‘politics is the art of the possible’. I was reminded of this by two videos I came across recently.

The first is this misery-fest from the Post Carbon Institute (PCI).

Yeah. Merry Christmas.

What we have in that little animated skit from the greens is the art of the impossible. On the Post Carbon Institute’s view, “We have to live within nature’s budget of renewable resources at rates of natural replenishment.” These limits become the parameters of our existence: the complete regulation of our productive lives.

But there are other ideas in the world, which don’t seem to conform to this stifling orthodoxy.

THE BEGINNING OF INFINITY from jason silva on Vimeo.

Taking his inspiration from physicist, David Deutsch, Jason Silva says, ‘If you look at the topogaphy of the island of Manhatten today, that topography is a topography in which the forces of economics and culture and human intent have trumped the forces of geology… extrapolating… that will be the fate of the whole universe.’

Trumping the forces of geology is, of course, anathema to the PCI.

I have no idea whether Jason Silva and David Deutsch would thank me for offering them as examples of thinking which sits at the opposite end of an axis to rank gutless miserablism. Perhaps the climate debate is one they would rather avoid — sensibly. It strikes me, however, that this should be the geometry of the debate about the future. To the PCI, history is a series of mistakes, which have taken us to the point of crisis. To the optimists, it is the foundation of ever greater leaps. The PCI speak of constraint, whereas the optimists speak about unleashing ever more creative potential. But there is an even more important difference.

Whereas the likes of the PCI have been able to turn their bleak vision into a system of ‘ethics’ and politics, the optimists’ ideas don’t seem to have any immediate moral consequences. There is no Intergovernmental Panel on Trumping Geology. On the contrary, there is only an intergovernmental panel on sobbing at our utter vulnerability in the face of geology. The impossibility of overcoming it — to any extent — is presupposed in the very foundations of the UNFCCC process: it discovers natural limits, and we are expected to codify them in international law. This is bizarre, not least because there are so many problems that can be faced by not taking seemingly ‘natural’ limits for granted. But also, because so much positive good cold be done in genuinely transforming the conditions of our existence by transcending such boundaries. Environmentalists seem to want them to remain in place. ‘Science’ in that arrangement is restrictive. On the optimists view, however, it liberates.

Environmental politics is about nothing more than regulation of eating, shitting, sleeping and f***ing: human life is reduced to these things, and each must be done ‘sustainably’, lest any opportunity for a more meaningful life opens up between them. So, the pessimists’ approach to the immediate problems facing the world is to regulate them out of existence. But poverty, war, famine and disease could not be abolished from the world by acts of international law intended to make the weather more ‘predictable’. Even if that did succeed, what would human life look like? A drab, miserable existence characterised by subsistence, in which each generation’s existence is identical to its parents’.

We see in the PCI’s animation, active hostility to progress — it is impossible. In the optimist’s video, there is dedication to the idea — the possibilities of human life expand indefinitely. We can argue forever about what ‘science says’ about the climate; the real debate is about its interpretation. The optimists need to recapture the moral and political ground from the miserablists.

The Polar Bear Affair. Part 1001.

The BBC’s Frozen Planet is continuing to fuel controversy. First, as discussed previously on this blog, the BBC’s decision to sell the seventh episode of the series — David Attenborough’s personal view of climate change and the crysophere — as an option led to screams and shouts from environmentalists. Environmentalists turned natural history into a morality tale.

A new brouhaha has broken out. A short opinion piece in the Radio Times — the BBC’s ‘what’s on TV’ guide — by Nigel Lawson has got polar Open University Polar Oceanographer Dr Mark Brandon all hot and sticky. Said Lawson,

Sir David Attenborough is one of this country’s finest journalists, and a great expert on animal life. Unfortunately, however, when it comes to global warming he seems to prefer sensation to objectivity.

Had he wished to be objective, he would have pointed out that, while satellite observations do indeed confirm that the extent of arctic sea ice has been declining over the past 30 years, the same satellite observations show that, overall, Antarctic sea ice has been expanding over the same period.

Had he wished to be objective, he would have pointed out that the polar bear population has not been falling, but rising.

Had he wished to be objective, he would have mentioned that recent research findings show that the increased evaporation from the Arctic ocean, as a result of warming, will cause there to be more cloud cover, thus counteracting the adverse effect he is so concerned about.

Had he wished to be objective, he would have noted that, while there was indeed a modest increase in mean global temperature (of about half a degree Centigrade) during the last quarter of the 20th century, so far this century both the UK Met Office and the World Meteorological Office confirm that there has been no further global warming at all.

What will happen in the future is inevitably unclear. But two things are clear. First, that Sir David’s alarmism is sheer speculation. Second, that if there is a resumption of warming, the only rational course is to adapt to it, rather than to try (happily a lost cause) to persuade the world to impoverish itself by moving from relatively cheap carbon-based energy to much more expensive non-carbon energy.

The Guardian’s resident eco-gossip columnist, Leo Hickman is reporting that Brandon penned an irate response to Lawson’s article, calling it ‘”patronising”, wrong and the “usual tired obfuscation and generalisation”‘. A more sober rebuttal appears on the Open University’s website. The following passage about polar bears caught my eye.

Is it true that polar bear populations are rising, and not falling as reported?

Many bear populations are dropping, as we say. Longer summers with no ice are probably the main reason why many polar bear populations are dropping. So what is happening to the bears? Different things in different parts of the Arctic, but here is what the Polar Bear Specialist Group of the IUCN Species Survival Commission say about it:

In 2009, of the 19 recognised subpopulations of polar bears, 8 are in decline, 1 is increasing, 3 are stable and 7 don’t have enough data to draw any conclusions. Figure 1 below compares the data for 2005 and 2009.

It is clear that the area of red (bear population trend decreasing) has significantly increased from 2005 to 2009 and the area of green (bear population trend increasing).

Pie charts struck me as a very peculiar way of representing population decline. It says less than nothing about population. For instance, the graph could be true, yet the total number of polar bears have increased in just the one region under study. Indeed, a million billion trillion zillion new polar bears could have landed in the one area from nowhere, and the graph would look exactly the same. Brandon seems to have taken his stats from the IUCN/SSC Polar Bear Specialist Group, and in particular this page which shows the different regions of their studies, and this table, showing the available data.

The 19 polar bear populations are divided as follows, according to the IUCN.

But if we rule out those 7 which ‘don’t have enough data to draw any conclusions’, we begin to see a problem.

There is insufficient data to say anything about the entire Eastern side of the polar region. Now let’s add the regions where populations are understood to be stable or increasing.

There are now 7 regions, of the 19, which are our focus. Working our way down the image, however, we find at Chukchi Sea that,

Abundance estimates are not available. The trend is believed to be declining and the status relative to historical levels is believed to be reduced based on legal/illegal harvest levels that were thought to be unsustainable. Sea ice loss is one of the highest levels in the Arctic. Combined impacts of high levels of legal/illegal harvest with rapid sea ice loss suggest that the risk for depletion is likely high.

In other words, the population of polar bears in this region have not been the subject of a population study.

Moving on to the Southern Beaufort Sea (SB), we discover the comment that ‘Estimated risk of future decline is based on vital rates estimated from the 2001-2006 data used in matrix-based demographic models that incorporate sea ice forecasts’. Models, not population studies are what see peril for polar bears. And indeed, going deeper into the analysis, it turns out that that,

The size of the SB subpopulation was first estimated to be approximately 1,800 animals in 1986. [...] Through the 1980s and early 1990s, observations suggested that the SB subpopulation was increasing. Amstrup et al. (2001) found that the SB subpopulation may have reached as many as 2,500 polar bears in the late 1990s. However, that estimate was not considered reliable due to methodological difficulties, and management decisions continued to be based on a population size of 1,800. Results from an intensive mark-recapture study conducted from 2001-2006 in both the USA and Canada indicated that the SB subpopulation included 1,526 (95% CI = 1,211 – 1,841) polar bears in 2006 (Regehr et al. 2006). This suggests that the size of the SB subpopulation declined between the late 1990s and 2006, although low precision in the previous estimate of 1,800 precluded a statistical determination. [...] Subsequent analyses of the 2001-2006 data using multistate and demographic models indicated that the survival and breeding of polar bears during this period were affected by sea ice conditions, and that population growth rate was strongly negative in years with long ice-free seasons[ ...] Thus, the SB subpopulation is currently considered to be declining due to sea ice loss.

Again, we see that it is models which predict population decline, not actual population studies. On to Lancaster Sound (LS), the comments for which are that

A population size of 2,500 bears was estimated in 1998 using mark-recapture methods. Population is through {sic} to be declining, because of highly selective harvest of male polar bears. [...] Demographic data are 11 years old. Population has highly selective harvest for males; however it is likely that selective hunting will decline with less sport hunting.

There’s an awful lot of estimating going on, about estimates of population done 14 years ago. Is this safe? Over to the Western Hudson Bay (WH).

The distribution, abundance, and population boundaries of the Western Hudson Bay (WH) subpopulation have been the subject of research programs since the late 1960s (Stirling et al. 1977, 1999, Derocher et al. 1993, 1997, Derocher and Stirling 1995, Taylor and Lee 1995, Lunn et al. 1997, Regehr et al. 2007). [...] Between 1987 and 2004, WH declined from 1194 (95% CI = 1020, 1368) in 1987 to 935 (95% CI = 794, 1076) in 2004, a reduction of about 22% (Regehr et al. 2007).

At last, we seem to have a number of studies to work from — a 22% reduction, even though the confidence intervals are quite wide, and do not exclude the possibility of there having been no population reduction at all. Over to Kane Basin (KB), which is,

A small subpopulation of approximately 150 polar bears, estimated in 1997. Harvest is thought to be unsustainable, and the population declining.

Thought to be… Maybe even good reason for thinking it… But it’s still just a thought. Anecdote, not data. On to Baffin Bay,

The current (2004) abundance estimate is less than 1,600 bears based on simulations using vital rates from the capture study (Taylor et al. 2005) and up-to-date pooled Canadian and Greenland harvest records.

Next!

The initial subpopulation estimate of 900 bears for [Davis Strait] (Stirling et al. 1980, Stirling and Killian 1980) was based on a subjective correction from the original mark-recapture calculation of 726 bears, which was felt to be too low because of possible bias in the sampling. In 1993, the estimate was again increased to 1,400 bears and to 1,650 in 2005. These increases were to account for the bias as a result of springtime sampling, the fact that the existing harvest appeared to be sustainable and not having negative effects on the age structure, and TEK which suggested that more bears were being seen over the last 20 years. The most recent inventory of this subpopulation was completed in 2007; the new subpopulation estimate is 2,142 (95% log-normal CI, 1811 – 2534). Using new recruitment and natural survival estimates (Tables 3, 4), the 10-year mean un-harvested geometric population growth rate is 0.98 ± 0.001 (Peacock 2009; see Research in Canada, this volume). DS is currently declining based on survival rates calculated from data collected up to the conclusion of the mark-recapture study in 2007. Ecological covariates associated with survival suggest that the decline may be as a combined result of short-term and local density dependence, stabilization of harp seal (Pagophilus groenlandicus) numbers and declining ice conditions.

So in fact the population of the Davis Strait increased over the last 30 years, in spite of global warming, from 726 to 2,142. But now it is supposed that they are in decline, in spite of there being no actual population study.

I’m not impressed. I believed that claims about polar bear population declines were based on polar bear population studies. But in two of these seven populations (Davis Strait and Southern Beaufort Sea) there was good evidence from actual population studies that numbers were increasing, which was overturned in the final analysis by ‘estimates’ of decline. Of the remaining 5, one region seems to have a robust claim to have shown a decline in population, but the rest are claims made on ‘estimates’ and simulations. Time to update the map.

Black shows the areas where there is insufficient data. Green shows regions where there is evidence of increase or stability. Red shows decrease. And yellow shows regions whose polar bear population numbers have been guessed. Grey is N/A.

Moreover, the main emphasis made by the PBSG is not the effect of global warming on polar bears, but humans shooting them. They discuss ‘sustainable’ levels of harvesting these creatures, which are ultimately dangerous pests as far as humans are concerned.

Brandon’s silly population pie charts seem to me to epitomise the way ambiguous data is concealed, and given a façade of scientific certainty. More to the point, it was wielded in a public and political debate about global warming policy. And this is the interesting thing about the cryosphere. Since it is so hostile, data series longer than 30 years are hard to come by. It is no surprise then, that this is where we find arguments about catastrophic climate change bury themselves — in uncertainty and ambiguity. The same is true of polar bear populations as it is of sea ice extent and air, sea and surface temperature. Where there are gaps in the knowledge, prejudices, assumptions and speculation fill the void. We see, as a matter of routine, claims that there are only N years left before the summer sea ice will be completely gone from the Arctic, and repeated claims that ‘the Northwest Passage has opened up for the first time in recorded history’. The Arctic and Antarctic are where fears about ‘runaway global warming’ and speculation about positive feedback systems are grounded, precisely because these regions are so poorly understood. And this lack of understanding is the reason idiot self-publicists go on futile missions to swim to the North Pole, or to trek across it ‘while we still can’ with moron scientists in tow, doing far more PR than research. In this respect, the cryosphere is is to climate change alarmism what quantum mechanics is to people preoccupied with parapsychology: it offers a possible mechanism to explain telepathy, ghosts, and even homoeopathy.

Thoughts on Climategate r1

Posted by Ben Pile on December 1, 2011
Dec 012011

I thought it might be worthwhile posting this presentation I gave in Edinburgh in Spring last year, following the first Climategate. It seems to me that the same is true of Climategate 2 as was true of the first: if there had been a more transparent debate, Climategate would not have have had the impact is has had. Some are calling for transparency in science, which I agree with, but I think it is a mistake to believe that even completely transparent science would answer the debate. It would make it harder to hide environmentalism’s political and ethical claims, perhaps, but it would be no guarantee, either of that or a bit more reflection on certain claims and why they exist, not just in the climate debate, but more widely also. For instance, the precautionary principle, and the deference to science, and the prostitution of its authority aren’t at all exclusive to the climate debate, but are almost ubiquitous in contemporary politics.


We often get comments on Climate Resistance that ask us what qualifications to speak about climate change I and my colleague, Stuart Blackman, have.

Neither of us are climate scientists.

To take issue with the moral and political arguments that emerge from the climate debate, is seen as equivalent to taking issue – to denying – climate science.

What I think this speaks most loudly about is the weight of expectations that climate science has to bear.

What makes climate science’s relationship with the social political sphere special and unusual, compared to other forms of science is that there is so much moral and political capital invested in the idea of a climate catastrophe.

It seems to me that that something like Climategate was bound to happen, and will continue to happen in the form of things like as Glaciergates and Africagates for instance as people start to see what climate science is and isn’t capable of producing for their moral and political arguments.

George Monbiot is one of my favourite writers, because you can always find something to say about what he says. And the thing I’ve chosen today is that George Monbiot believes that gay people are more moral than straight people, because they won’t produce any carbon-emitting babies.

I’m not pointing it out to say that gay people are immoral, but because I don’t see how they can be any more or less ‘moral’ than people who happen to be born straight.  This is just a bizarre moral framework.

We also hear from the likes of the New economics foundation and the green party that there are just ten years left to save the planet. If you go to the NEF website, you can even hear the clock ticking, down from 100 months.

According to Susan Watts, the science… Science!… Editor of BBC Newsnight, ‘scientists have calculated that Obama has four years in which to save the planet

So these are the kind of arguments people are trying to support with climate science.

But it is not just journos and activists. This is academics from many different disciplines,

Ian Roberts of the London School of Hygiene and Tropical Medicine tells us that fat people contribute more to climate change than thin people do. Because as they get fatter, they enter a positive feedback system, in which they increasingly use labour-saving devices to cart their increasingly fat bodies around, as they become less and less physically able. So they use escalators, lifts, cars, etc, pumping out CO2 all the while.

Using carbon is the equivalent of slavery, according to Jean-Francois Mouhot, a historian at the University of Birmingham.  If we compare our current attitude to fossil fuels and climate change with the behaviour of the slave owners, there are more similarities than one might immediately perceive.

There are now special climate change ‘ethics’, that occupy the minds of philosophers. The scientific certainty that we are destroying the planet has made black and white the moral questions that have haunted moral thinkers since ancient times.

This cheap moral realism gives purpose to special climate change psychologists, who are employed to find out why the moral message isn’t getting through to the public.

They set about working out how to communicate climate change to people who don’t believe it, and try to locate the processes that may be going on in the heads of those who refuse to believe it… The deniers.

There doesn’t appear to be an area of public life that has not been framed in the terms of climate change. The idea of climate catastrophe has become the prism through which we see ourselves, the world, and our relationship to it.  Everything is captured in this one idea that the world is about to be destroyed.

This is a political and ideological phenomenon, not something which has just emerged from climate science, to which conventional politics has simply responded after considering it carefully.

And yet, if you look at how the arguments within this system are constructed, they nonetheless all begin with the claim that “climate change is happening”. I think this is mistaken view. Not that climate change isn’t happening, but that it is a mistake to [allow] ‘climate change is happening’ [to be] the beginning of all these moral calculations.

What happens at UEA, then, appears to be the keystone of all the arguments that ensue.

And so it is no surprise that this is where people have been focussing their hacking efforts. And it is of no surprise that what has been found reveals that the source of all these moral and political arguments is not so clear cut.

I think sceptics have made a mistake here. And that a peak behind the firewall didn’t tell us anything that we didn’t already know.

Rather than a process of the science informing the political or otherwise social, the dynamic is the other way round. That is to say that the politics is prior.

Monbiot puts it best: It [the campaign against climate change] is a campaign not for abundance but for austerity. It is a campaign not for more freedom but for less. Strangest of all, it is a campaign not just against other people, but against ourselves.

 

Monbiot has had to make his apology, because he has invested his entire perspective on the world, in “The Science”.

David Attenborough is even less reflective. He says.

“Instead of controlling the environment for the benefit of the population, perhaps it’s time to control the population to allow the survival of the environment”.

The President of the Royal Society – the organisation that promotes the scientific view of the world, Martin Rees, writes in “our Final Century” that our odds of surviving the next 100 years are just 50/50.

I mention Rees because he was on the Today program this morning, talking about the IPCC review — a review of the review by the reviewers — and it struck me more than ever that Rees’ role was once occupied by people who were proud to speak truth to power. Now, he, the Royal Society, and so many institutions that have attached themselves to the climate issue, instead speak Official Truth FOR official power. And I think that is a dangerous thing.

The sense of overwhelming crisis is being used to give authority to the kind of political ideas I think we ought to reject. These political ideas, since they make a virtue of being anti human, depend instead of our consent, on empirical substance for their moral authority. That substance comes from organisations like of the CRU.

So there are two sense in which the politics is prior to the science.

First, there are the ideological presuppositions that we are powerless to address the things produced by our sense of alarm and imminent doom. We passively accept our fate, and the fate of others.

For instance, the Global humanitarian Forum released a study last year which claimed that 300,000 people a year die from the effects of climate change. This doubles the WHO’s estimate from 2002. They project that half a million people will die, in 2030, they say, from the same malaria, malnutrition and diarrhoea, caused by climate change. This, they say makes climate change the biggest issue facing mankind.

Never mind the 10 million people who died according to the WHO in the very same report, from first order effects of poverty.

We feel so unable to understand the social world, that the only way we can conceive of its problems is by naturalising them through ideas about the environment and climate change.

Second, there are the searches for authority in the statistics and projections such as those produced at the CRU.

The academy, government, and the media each seem to have rooted themselves in this crisis, and define themselves by it.

The crisis gives orientation to journalists who are disoriented by a world that no longer divides into left and right, and East and West.

It breathes new life into dusty old academic departments who have had relevance and targets foisted upon them from above.

And it gives the government legitimacy in a time when no one can be ‘bovvered’.

Finally, then, in order to make productive sense of what the science ‘says’, we need to be sure that we know what science has been asked, and what it has been told, and what it is really studying.

The climate crisis — and all of its little debates and fights like Climategate– are a projection of much deeper problems and crises in society.

Against Evidence-Based Policy-Making

Posted by Ben Pile on November 28, 2011
Nov 282011

I have a post at the Independent on the Battle of Ideas blog about the problems with ‘evidence-based policy-making’.

The big lie about evidence-based policy-making is that it’s based on evidence. Evidence no more produces and speaks for itself than cars decide their destinations. Policy-making begins when people perceive a need for a policy. Even when it is evidence which moves a person to speak for a policy, such evidence is always seen through the prejudices, preconceptions and presuppositions that every human sees the world through. The desire for objectivity in politics, while seemingly sensible, belies a terrible loss of self-confidence, and can typically hide what should be political decisions under the guise of ’science’.

I was trying to make the point that a lot is presumed about science’s ability to answer deeper political and moral questions, and of course that politicians and other officials are somewhat promiscuous in their use of ‘evidence’. It’s not an argument against evidence, though no doubt some people will read it that way.

Climategate II – Derailing the Re-Railing

Posted by Ben Pile on November 22, 2011
Nov 222011

So… Part two of the Climategate series is out. Popcorn is flowing.

It’s too early to say anything that isn’t already being said about what the new emails revealed. But, as per usual, what’s being said about what the emails do or don’t reveal is interesting.

Leo Hickman is the first to the scene

The lack of any emails post-dating the 2009 release suggests that they were obtained at the same time, but held back. Their release now suggests they are intended to cause maximum impact before the upcoming climate summit in Durban which starts on Monday.

The BBC’s Richard Black was not far behind, quoting the a University of East Anglia (home to many of the climate researchers)…

The university says it has “no evidence of a recent breach in our systems”, and suggests that the cache – posted on a Russian server – has “the appearance of having been held back after the theft of data and emails in 2009 to be released at a time designed to cause maximum disruption to the imminent international climate talks”.

The central argument from those invested in the climate debate seems to be that the release of these emails is a ‘deliberate attempt to derail the climate talks in Durban’.

It would seem so. But when is the best time to publish information pertaining to the climate debate? The proximity of the COP17 meeting didn’t stop the International Energy Agency announcing just two weeks ago that,

Without a bold change of policy direction, the world will lock itself into an insecure, inefficient and high-carbon energy system [...] The agency’s flagship publication, released today in London, said there is still time to act, but the window of opportunity is closing.

And the looming meeting in Durban didn’t stop the publication of the IPCC report into extreme weather:

Regarding the future, the assessment concludes that it is virtually certain that on a global scale hot days become even hotter and occur more often. “For the high emissions scenario, it is likely that the frequency of hot days will increase by a factor of 10 in most regions of the world”, said Thomas Stocker the other Co-chair of Working Group I. “Likewise, heavy precipitation will occur more often, and the wind speed of tropical cyclones will increase while their number will likely remain constant or decrease”.

Why weren’t the journalists at the Guardian as suspicious of the timing of these documents as they are now about the release of these emails? The two reports above, are consistent with the raised tone with which the Guardian has been reporting on climate matters recently. Fiona Harvey, for instance, covered the IEA’s report with the dramatic words:

World headed for irreversible climate change in five years, IEA warns
If fossil fuel infrastructure is not rapidly changed, the world will ‘lose for ever’ the chance to avoid dangerous climate change
The world is likely to build so many fossil-fuelled power stations, energy-guzzling factories and inefficient buildings in the next five years that it will become impossible to hold global warming to safe levels, and the last chance of combating dangerous climate change will be “lost for ever”, according to the most thorough analysis yet of world energy infrastructure.

And Harvey was equally credulous about the IPCC report.

Extreme weather will strike as climate change takes hold, IPCC warns
Heavier rainfall, storms and droughts could wipe billions off economies and destroy lives, says report by 220 scientists
Heavier rainfall, fiercer storms and intensifying droughts are likely to strike the world in the coming decades as climate change takes effect, the world’s leading climate scientists said on Friday.

There are double standards in play: it’s okay to step up the alarm on the eve of climate talks, but to throw any questions about the provenance of climate change alarmism into the mix is to ‘deliberately derail’.

I’ve made the point about timing myself, before. It seems that each autumn, the alarmist narrative goes into overdrive. Back in 2008, for instance, the ink on the UK’s new Climate Change Act was barely dry by the time the COP meeting was underway. As I said at the time,

The point of all this is that the UK Government’s need to have successfully created a a strong climate law, in place by now, December the 1st 2008, is owed, not to the Government’s commitment to ‘saving the planet’, nor even the UK population, but to the designs its members have on being ‘world leaders’.

Timing is everything, after all.

Nov 172011

This story was intended for Spiked-Online, who may be publishing it at some point, but I wanted to get it out a bit sooner.


A new scientific study of the Earth’s temperature record aimed to rescue climate science’s reputation from the aftermath of the ‘Climategate’ affair. Advocates of climate policies have long argued that unimpeachable science has driven policy-making, but climate sceptics argued that due scientific process had not been observed. Climategate and other revelations  that seemed to undermine climate science seemed to make the sceptics’ case. Rather than bringing clarity to the debate, however, the new study inadvertently demonstrates that the desire for unimpeachable scientific answers belies a fundamentally political debate.

The ‘Climategate’ affair broke In late 2009. Thousands of private emails between climate researchers based at the University of East Anglia’s Climate Research Unity were leaked onto the internet, the contents of which raised questions about the propriety of high profile scientists. Whether or not they had done anything wrong, the authors of these emails seemed to have been caught taking liberties with statistics, concealing their data and methodology from scrutiny, and treating the critics of their research with contempt. In the wake of Climategate, Professor of Physics at the University of California at Berkeley, Richard Muller said,

Quite frankly as a scientist, I have a list of people whose papers I won’t read any more. You’re not allowed to do this in science; this is not up to our standards. [...] This is why I’m leading a group to re-do all this in a totally transparent way.

The first results from Muller’s group — Berkeley Earth Surface Temperature (BEST) — have been released. Rather than being released through publication in a peer-reviewed journal, however, Muller and his associates took the somewhat unusual step of publishing draft copies of their studies, and made themselves available for comment in the media. Fuelling controversy further, Muller wrote an article for the Wall Street Journal, which an editor gave the title, ‘The Case Against Global Warming Skepticism — There were good reasons for doubt until now’.

This comment came to the delight of climate activist journalists, scientists and other commentators. ‘Sceptical climate scientists concede Earth has warmed’, announced the New Scientist. ‘BEST reconfirm: warming is happening’, said the influential Carbon Brief blog, which is staffed predominantly by activists from environmental NGOs. Channel 4 News’s science correspondent, Tom Clarke was asked, ‘so does this finally vindicate climate change science’. ‘In a word, yes’, replied Clarke. According to Clarke, the BEST team’s discovery that the world is warming got those implicated by Climategate off the hook.

From the copy it had generated, it would seem that BEST had ended the debate. But climate scientist, and contributor to the BEST project, Judith Curry observed, ‘the spin on the press release and Muller’s subsequent statements have introduced unnecessary controversy into the BEST data and papers’. Curry’s comments were picked up by Daily Mail journalist, David Rose, who wrote

‘The Mail on Sunday can reveal that a leading member of Prof Muller’s team has accused him of  trying to mislead the public by hiding the fact that BEST’s research shows global warming has stopped.’

Exciting stuff. But not what Curry had told Rose. ‘To set the record straight, some of the other sentiments attributed to me [in Roses's Daily Mail article] are not quite right’, she wrote on her blog. Meanwhile, Muller himself was distancing himself from the headlines of the article in the Wall Street Journal. ‘It doesn’t represent the article’, he told a journalist in New Mexico. But sceptics pointed out that Muller had said,

Without good answers to [sceptics' concerns about various attempts to measure global warming and its effects], global-warming skepticism seems sensible. But now let me explain why you should not be a skeptic, at least not any longer.

Confusion reigns. The coverage had by now been established as so much he-said-she-said. Sceptics pointed out that, in spite of the claims that the debate was now over, the BEST study still had argued that ‘human component of global warming may be somewhat overestimated’. The data still reflected a stalling of global temperatures over the past decade, and the study’s attempt to rule out one of the main concerns sceptics have about the way temperature data is recorded appear to have some serious shortcomings. Even the project’s leader didn’t seem to be making consistent statements about what his research meant for the climate change debate. None of this phased the BBC’s environmental correspondent, Richard Black, who continued covering the affair in much the same way. Wrote Black,

The original “hide the decline” claim is one of the most easily de-bunked in the entire pantheon of easily-debunkable “sceptic” claims.

Phil Jones wrote the email in 1999, immediately following what still ranks as one of the hottest years on record, and well before the idea of a “slowdown” or “hiatus” or even “decline” in warming gained currency.

So it can’t have had anything to do with hiding a global temperature decline.

The expression ‘hide the decline’ is what ultimately led to Climategate becoming such a major story. Defenders of those implicated by the emails argued that ‘hiding the decline’ referred to a mathematical technique, rather than a conscious effort to deceive. But there was nonetheless good evidence that something untoward had been intended. And it was this that moved Richard Muller to establish the BEST project, as he explains in this video.

If the sceptics’ ‘hide the decline claim’ was as easy to debunk as Black claimed, Muller — a Professor of Physics — would not have needed to bother with the BEST project. But Black had invented the claim he had attributed to sceptics, for which he later apologised. But the cat was out of the bag: rather than accurately representing the arguments made in the debate, he had picked a straw man to argue with, rather than sceptics.

Had Black wished to overcome the limitations of mediocre journalism, to get to the heart of the debate, there are many well-informed sceptics he could have turned to for comment and advice. One such is Andrew Montford, author of ‘The Hockey Stick Illusion’ and a report published by  the Global Warming Policy Foundation (GWPF) on the Climategate affair (PDF).  ‘He’s not representing what the sceptic’s arguments are’, Montford told me.

The majority of sceptics say ‘yes, carbon dioxide is a greenhouse gas, and that the world has warmed’. That’s really hasn’t been argued very much for a long time. There are  few people out there arguing [against] that, but really not very many. What you read about sceptic objections in the newspapers is not really what the sceptics’ objections are.

Montford agrees that there is no definitive ‘sceptic’ argument. This fact mirrors the many varied positive claims that are made on the other ‘side’ of the climate debate, but which seem to emerge axiomatically from the fact that ‘climate change is happening’. For many sceptics, too much rests on the claim, however true it is, which is in the first place a question of degree with a considerable amount of latitude, even within the ‘scientific consensus’. A concatenation of non-sequiturs cascade from the first: about sea-level rise, species extinction, drought, famine, resources wars, and so on. And these consequences seem to cascade just as ‘inevitably’ to the remedy: the creation of powerful political institutions, a transformation of the global economy, and the de facto rationing of energy and regulation of lifestyle.

In short, the climate debate is by definition as complex as the whole of human social life and natural science combined. But such a complex state of affairs does not make for easy reportage, especially by journalists who don’t seem able to digest nuance and complexity, let alone reflect meaningfully on them. And so to take issue with any aspect of the debate is to seemingly deny that the earth has warmed approximately 0.7 degrees centigrade and that humans had some part in it.

So what does the BEST study really reveal, according to sceptics? And how has it changed things in the post-Climategate world? Montford tells me that,

[BEST] doesn’t really change anything. People like Steve McIntyre [the climate blogger who first raised issues with how historical temperature records were created] were saying long before Climategate: you’re not going to find a smoking gun in the temperature record, and you always had the satellite records which were telling pretty much the same story. [The Climategate researchers] are just being civil servants and trying to hide the fact that they’re not doing very much, they haven’t got many quality-control procedures, and they’ve got commercial incentives to keep everything under wraps. That’s the only reason for the secrecy.

So it would seem that few, if any, sceptics were claiming that there had been no warming, or that the scientific data had been plucked out of thin air. BEST merely confirmed what most sceptics agreed was probably happening anyway. Nonetheless, the BEST story was widely reported as representing a meaningful end to the climate debate. Muller had made ambiguous comments, which were amplified by an incautious sub-editor. A phantom news story appeared out of an uncontroversial study. Journalists were reporting from inside their own heads, not from the real world. And that is an interesting phenomenon, and one which needs some explanation.

Complex debates are reduced to simple, moral stories of ‘scientists versus deniers’, in part because of the shortcomings of news organisations and their journalists’ attachments to the debate. Anxieties about the end of the world give moral orientation to otherwise disorientated commentators. Taking a stand that claims to ‘save the planet’ elevates journalists, who without climate change, would quite probably struggle to overcome mediocrity, to define a sense of purpose for themselves. It looks like bravery, but it is merely vacuity that drives sensationalism.

However, vapid journalism — churnalism — is not the whole story. The controversy generated not by BEST itself, but by the treatment of its result, speaks about wider and unrealistic expectations of science. Politicians, activists, and scientists are as vulnerable as journalists to the idea that science can supply them with uncorrupted objectivity and unambiguous instruction. Given that Muller himself didn’t seem able to supply clarity to the debate — in spite of the science — it is no surprise that arguments downstream have even greater difficulty getting the story straight. ‘Science’, rather than shedding light on the material world, obscures the debate.

Climategate, and other events in late 2009, such as the failure of the COP15 meeting at Copenhagen to find a successor to the Kyoto protocol revealed that too much had been invested in science. Science was, after all, produced by humans prone to error and vice. Climate scientists had refused to reveal their data and show their workings, and several alarming claims about climate change were found to be groundless. This would have all been without consequence, had there been more circumspection about the role of science. But rather than reflect on such expectations, the BEST project aimed to reproduce the science with virtue: ‘transparency’. It made no difference, though, because before it had even been peer-reviewed and published, it became the peg onto which the same old prejudices, myths and politics were hung. BEST now ‘vindicated climate science’, exonerated climate scientists and forced ‘sceptics’ to concede that the earth had warmed.

BEST says nothing about any of these things, of course. Sceptics weren’t ‘denying’ that the world had warmed. The debate wasn’t divided between climate science and its critics. And ‘Climategate’ remains an embarrassment to those who refused to release data (or concealed it) and its methodology, as Muller explained. Science cannot end the climate debate, because the climate debate has very little to do with science.

Natural History — a Morality Tale

Posted by Ben Pile on November 15, 2011
Nov 152011

I have no idea about the truth of a story in the Telegraph today. As usual, however, I find that the way the facts — whatever they are — are treated is more interesting than the reality.

BBC drops Frozen Planet’s climate change episode to sell show better abroad
The BBC has dropped a climate change episode from its wildlife series Frozen Planet to help the show sell better abroad.

Hmmm. Okay, I am wondering if it is true now. You have to wonder…

British viewers will see seven episodes, the last of which deals with global warming and the threat to the natural world posed by man. However, viewers in other countries, including the United States, will only see six episodes. The environmental programme has been relegated by the BBC to an “optional extra” alongside a behind-the-scenes documentary which foreign networks can ignore.

So I’m wondering, now, did the BBC put out a press release saying ‘you don’t have to buy the seventh episode — it’s an optional extra, for non-climate sceptics’? I find it hard to imagine. So where did the story come from?

Campaigners said the decision not to incorporate the episode on global warming as part of the main package was “unhelpful”. They added that it would allow those countries which are sceptical of climate change to “censor” the issue.

Others suggested that the Corporation should have offered “On Thin Ice”, the global warming episode, for free due to the importance of the issue.

Ahhh. Campaigners. You see, it probably wasn’t an issue…

However, the BBC said it was standard practice to offer international clients only the parts they wished to purchase.

… until the campaigners turned it into one. And, moreover, until the Telegraph indulged them.

A spokeswoman for the BBC said it was not be feasible to force networks to buy the climate change episode as it features Sir David talking extensively to the camera and there are many countries where he is not famous. Many environmentalists are ardent fans of the show for highlighting the fragile beauty of the natural world.

Fragile beauty? This is the myth of ‘fragile beauty’. ‘Beauty is in the eye of the beholder’, after all. And in much the same way, so is fragility. It’s not until you believe that the world is ‘fragile’ that change and ‘destruction’ become equivalents. Environmentalists presuppose ‘balance’ in the world. Thus, any change can only be explained in terms of a destructive agent — humanity. It’s this idea of fragility and balance that leads to ideas about ‘tipping points’, ‘sustainability’ and ‘gaia’. That’s not to say that the changes seen in the Arctic are neither problematic, nor our fault, but that the idea of ‘fragility’ precedes a treatment of the facts, and precludes a sensible debate about them. Hence, there are some angry voices about the fact that broadcasters are free to buy the episodes they desire. The Telegraph quotes a number of such angry voices,

Harry Huyton, the head of climate change for the RSPB, said: “Selling Frozen Planet in two parts seems rather unhelpful because it suggests that it would be perfectly reasonable not to show the bit with the climate message.

“We would encourage the networks that haven’t bought the whole thing to think again and not to censor the issue.”

Tony Juniper, an environmental adviser and former head of Friends of the Earth, said: “It raises questions about the BBC’s overall environmental coverage, which is patchy and inconsistent.”

He added that the BBC’s attitude allowed other countries to opt out of the climate change episodes for “political reasons” or because they had already covered the issue with previous programmes.
A spokesman for Greenpeace, the environmental group, said: “It’s a bit like pressing the stop button on Titanic just as the iceberg appears.

“Climate change is the most important part of the polar story, the warming in the Arctic can’t be denied, it’s changing the environment there in ways that are making experts fearful for the future.”

It’s not clear how Toby Juniper has determined that the BBC’s coverage of the environment is ‘patchy and inconsistent’. The ‘science and nature’ pages of BBC’s iplayer site reveal that the BBC is pretty keen on reporting from the natural world. Moreover, as recent controversies over the Jones report, and Richard Black’s instructions to his juniors reveals, the BBC takes a pretty dim view of climate scepticism. As I’ve argued before, greens’ lack of sense of proportion is made up for by their sense of persecution. Huyton’s allusion to ‘censorship’ is picked up by Business Green’s James Murray, who is ‘none too impressed with the BBC’s decision to censor its nature documentary for foreign audiences

Unsurprisingly, (and this is more the fault of the scientific and political community than the BBC), 10 of the 30 networks to buy the show have opted for the censored version. There is no prize for guessing the US is among those markets where TV execs have decided they do not like scientific reality to impinge upon their inspiring nature footage.

Censorship? Censorship? Really? I bought a Sunday paper this weekend, but decided to leave the supplements at the newsagents, as I wasn’t interested in them, and I had a fairly long walk up a hill home. Was I censored? I freely made a decision not to take the parts of the paper I didn’t want with me. The shopkeeper agreed to keep them, and dispose of them himself. In much the same way, the BBC, as seems to be normal practice, offers its series in parts, to broadcasters, so that they can freely chose to screen what they wish.

Where is the censorship?

‘Censorship’, in its day-to-day usage, means an official intervention, to prevent the broadcast of material. But we see now that, in the strange moral universe created by environmentalists, ‘censorship’ has been somewhat transformed. Censorship is now the failure to broadcast the official account of something. That is to say that if you don’t broadcast something which environmentalists tell you that you should broadcast, you are censoring. In other words, environmentalists have precisely inverted the meaning of ‘censorship’. This is amazing, not least because ‘censorship’ is something we typically equate to the ‘Orwellian’ use of language, and now we see the word ‘censorship’ itself being subject to revision along the lines of ‘newspeak’. But perhaps this dystopia is a better account of what environmentalists have in mind…

Perhaps this is a bit of an over-reaction. Nobody is forcing our eyes open, and holding our head to the screen. Yet. But the point remains, environmentalists seem to believe that exposure to their narrative, over images of change will provoke a change in the audience’s moral conscience. Moreover, we shouldn’t be allowed to enjoy the stunning photography, or images of the cryosphere in general,
without being told the story of climate change.

Natural history, then, becomes a morality tale. Or perhaps worse, a secular creation myth. Rather than ‘censorship’, the word James Murray and Harry Huyton were searching for was ‘blasphemy’. To show images of the Arctic without the sermon would be to puritans what the godless celebration of Christmas and Easter is, without the story of Christ: mere hedonism.

To the main point: what’s wrong with enjoying the BBC’s epic photography, for it’s own sake, eschewing the moral message? It would be hard to deny that the BBC’s natural History unit has a unique sense of spectacle, and some extremely talented staff. There is nothing wrong with it, of course, except for the fact that enjoying such images, divorced from the environmentalists’ narrative is ultimately to enjoy distance from nature. What you see, when you watch these programmes is not intrinsic beauty, but the culmination of thousands of man-hours, and £ millions of technical processes: skilled camera operators and production crews, and expensive and time consuming post-production, recolouring, re-timing, and editing the footage.

If you were actually sat at the Arctic, you would, after some moments of awe, likely become quite bored quite quickly, and yearn for home, even if it is, like mine, a flat in a fairly brutal 1970s block of cubic modernity. You would also get quite cold. And hungry. ‘Beauty’ — aesthetics in general — would become less and less of concern, and thoughts about what you’d prefer to eat would give way to actual hunger, which would force you to eat regardless of taste. You would be less concerned with the ‘fragility’ of nature than with your own imminent demise.

It’s only with such distance that natural history as a morality tale makes any sense. It’s only when were not subject of nature’s whims that nature seems to be ‘fragile’. It’s only when we’re warm and snug that we can be forced to consider what life would be like without warmth and snugness. And that’s why various greens have got their knickers in such a twist about the BBC not forcing overseas broadcasters to buy its miserable, moralising follow-up.

Indirect Action

Posted by Ben Pile on November 2, 2011
Nov 022011

Predictably, the UK’s first shale gas fracking plant has become the site of ‘direct action’. Once again, a small number of protesters have decided to inflict themselves on the rest of the world. The Guardian reports this morning that,

Protesters from the UK’s anti-fracking network Frack Off have invaded a test drilling site in Lancashire and occupied its drilling rig.

A group of nine people ran on to the site operated by Cuadrilla Resources at Hesketh Bank near Preston before dawn and used climbing equipment to clamber up the metal structure. They have fixed themselves on top and said that they plan to stay as long as possible. Other protesters are expected to hold a rally at 3pm outside the site.

This is the MO of the small number of environmental activists in the UK. Previously, they have trashed crops and attempted to shut down power stations and airports, and even parliament itself.

Isn’t the point of a protest to demonstrate popular support? Yet few of these instances of direct action ever muster more than a few dozen people. The environmental movement’s attempts at conventional forms of protest have resulted in disappointment — no more than a few hundred will turn out. Thus, to elevate their campaigns, environmental activists turn to spectacle: dangerous stunts that guarantee media coverage. For decades now, this has been the way environmentalists have attempted to engage the public. Yet they are more isolated than ever, and have completely failed to share the values and ideas which inform their actions.

For instance, there may be perfectly legitimate reasons to protest about the development of fracking. People living nearby may feel that they are inadequately protected from any possibly accidents, and that the fracking company will not be held sufficiently liable for any damage they cause, and may be encouraged to take risks. Hell, who could object, even to a protest about carbon emissions? But these are not the complaints of the fracking protesters. Their website reveals the real object of their criticism:

The actual problem we face is that civilisation has too much energy, not too little. This addiction to fossil fuels has driven a binge of extreme exploitation of our environment and our social structures, that is threatening our very existence. Fancy technological schemes to try to continue our present orgy of consumption and waste indefinitely are inevitably doomed to failure. Only a transition to a much less energy intensive way of living can save us from complete disaster.

It is civilisation itself — not hydrological fracturing — which annoys the protesters.

They should tell the 5 million households in the UK who live in ‘fuel poverty’ that ‘civilisation has too much energy’. They should tell the families and friends of the 2,700 people who die each year as a consequence that there is a ‘a binge of extreme exploitation of our environment and our social structures’. They should explain to the 1.6 billion people in the world who don’t have any access to electricity that ‘a much less energy intensive way of living can save us from complete disaster’. The Guardian quotes protester, Colin Eastman:

Conventional fossil fuels have begun to run out and the system is moving towards more extreme forms of energy like fracking, tar sands, and deep water drilling.

The move towards ‘extreme energy’ is literally scrapping the bottom of the barrel, sucking the last most difficult to reach fossil fuels from the planet at a time when we should be rapidly reducing our consumption altogether and looking for sustainable alternatives.

In the UK fracking for shale gas is planned alongside, not instead of, extraction of conventional fossil fuels like coal.

It’s a myth that conventional fossil fuels are running out. ‘Extreme forms of energy’ are being developed because civilisation is getting better at finding more abundant sources of energy. That’s what civilisation is: it creates the possibility of better and better ways of living, of more freedom and greater material progress. The Frack Off campaigners are intolerant and nervous of it. Their claim is that we are inviting ecological disaster, but this belies anxiety about disorder in the human world: on their view, nature serves to discipline our sinful, profligate selves. Civilisation means finding new things, rather than existing in a kind of social stasis, in back-breaking ‘harmony’ with nature.

The moral argument for more energy — for ‘extreme energy’ needs to be reclaimed. Cheaper, and increasingly abundant energy is a good thing because it increases the possibilities of human lives. Being restricted to Nature’s Providence is a bad thing, because it limits the possible freedoms humans can enjoy. Most people realise it, and only a few are prepared to climb drilling rigs to campaign against civilisation. Yet they’re the ones who get in the papers.

Still Subsidising the Argument…

Posted by Ben Pile on November 1, 2011
Nov 012011

Something of a brouhaha is developing in the debate about the extent of subsidies for renewable energy in the UK. Green energy campaigners are complaining about a proposed cut in the Feed-In Tariff (FIT) scheme which promises owners of domestic solar PV up around £0.433 per kilowatt hour, but which will ‘only’ give them £0.21 per kWh. James Murray, editor of Business Green said in the wake of the leaked proposal that,

The government is about to deal a crippling blow to a fast expanding green industry that is serving to cut carbon emissions and create jobs.

In the same article, Murray also claims that the solar industry employs more people than the UK’s nuclear energy sector. According to many of the government’s new critics in the green energy sector, there are 25,000 jobs in solar energy in the UK.

That seems like an extraordinary claim to me. According to the Digest of UK Energy Statistics, nuclear power provided 69,098 gigawatt hours (18% of total) of electricity to consumers in 2009, whereas there were only 50 megawatts of installed solar PV capacity on the grid in the same year. That makes a comparison in equivalent terms of output difficult. DUKES doesn’t even bother, the sums are so small, so it lumps production from solar PV in with wind. But if we assumed that solar panels were 100% efficient (had a 100% load factor), and the sun shone 24 hours a day, the UK’s fleet of solar panels would have produced just 438 gigawatt hours — a 160th of what the UK’s fewer nuclear energy employees produced. But the sun doesn’t shine every day, and solar PV struggles to produce a load factor of more than 20%. Let’s call it 15%. It now looks like solar PV in the UK produced just 66 GWh of electricity in 2009 — less than a thousandth of what the nuclear energy sector did, with fewer people.

But there’s an even better way to show that the figure is bogus. Even if the UK’s solar PV fleet increased by 50MW (50,000 KW) of capacity each year, that would mean that each job in the sector only produced 2KW of capacity. That is less than one domestic solar PV installation per year, per sector employee.

Then let’s imagine that each of those jobs costs £25,000 a year. That would mean a total of £625 million. So in order to compete with nuclear in labour terms, the solar sector needs to become 1,000 times more efficient. Anyone who wants to defend subsidies to solar energy on the basis that it ‘creates jobs’ needs to take a reality check. There are much better things that could be done with that money. It’s hard to think of a more futile and costly gesture. It would be better to simply give 25,000 people £25,000 each, every year, because then there would be no need to pay for the solar PV panels and no need to subsidise their pitiful output.

I had a look to see the source of the 25,000 jobs claim. The closest thing I could find was this article, which claimed that

According to the latest REAL Assurance data an estimated 25,000 UK jobs have been created as a direct result of the feed-in tariff (FiT). Despite already exceeding all expectations, the Renewable Energy Association (REA) believes even this huge figure is likely to be underestimated as the REAL team only deals with companies working on small-scale installations.

It looks like James Murray was confused about the statistics…

In the solar industry alone there are currently 4,000 companies registered with REAL in the UK with approximately 100 new members signing up each month. Each one of these companies has from 1-2,500 employees, showing the sheer dominance the solar sector has in the UK. At this growth rate the REA estimates that solar jobs will exceed 7,000 by April 2012, with more jobs created providing the industry remains supported.

But the more accurate figure hardly puts the solar PV sector in a better light, if you’ll pardon the pun. It means that the average solar PV job produces just 7KW of installed capacity per year (assuming that capacity is increased by 50MW per year, which is more than optimistic).

Stuff the subsidies for solar PV. They make no sense. At all. Just as the statistics produced in defence of the UK’s energy and climate policies make no sense. I’m struggling to not to use expletives and other words that are no stronger than ‘innumerate’ to describe the nonsense that we’ve seen over the last few weeks (see previous posts). Forget hockey sticks. Forget ‘hiding the decline’. The real statistics-abuse happens closer to home — in the policies and politics of the climate and energy debate. With such liberties taken with arithmetic, it makes no difference what graphs depicting global temperature change say.
