You almost certainly won’t have spotted the publication of Defra’s new set of statistics on agriculture and climate change yesterday. But before you nod off, check out this clever piece of spin by the statisticians.

Between 1990 and 2009, total greenhouse gas (GHG) emissions from UK agriculture are estimated to have fallen by 21%.

So far, so good: it looks like British farmers have been doing their bit with …

This year, PIRC turns forty.

We were founded in 1971 by campaigner Charles Medawar and veteran social entrepreneur Michael Young, who also set up, amongst many other organisations, the Open University. PIRC’s creation was inspired by the work of legendary US civic activist Ralph Nader, and it was his brand of activism – using careful research and cogent advocacy to empower citizens and hold governments and companies to account – that Medawar and Young sought to bring to British shores.

PIRC in its 1970s incarnation, replete with cool hair.

The UK’s total emissions are set to rise, PIRC can reveal – as shown in yet-to-be-published calculations by the government’s Carbon Trust.

Whilst on paper, Britain’s carbon emissions have declined, in reality they have grown – once emissions from imported goods are factored in. From a consumption perspective, the UK’s emissions have risen by 19% since 1990. New data from the Carbon Trust shows that by 2025 the UK’s …

A movie that is now being launched in the UK called Collapse shows Michael Ruppert chain-smoking his way through visions of social and economic disaster. It is symptomatic of the utterly self defeating way that peak oil  and climate change are typically communicated.

Ruppert is a media generated phenomenon who brings together a cluster of conspiracy theories under one house brand. His endlessly promoted back story- as the LAPD cop who faced dismissal for revealing the CIA supply of drugs- is the stuff of a hundred good-cop movies . His highest profile accusation, that Dick Cheney personally ordered the 9-11 attacks, is downright nuts.  It is directly descended from the  conspiracy theories that the CIA ordered the shooting of J F and Bobby Kennedy. No big surprise – Ruppert promotes these myths too.

But never mind Ruppert, what is interesting for the Climate Denial blog is the appearance of this film at this time and the way that it presents its case. I have not yet had a chance to see the entire film though have seen long extracts. Here is the trailer – judge for yourself.

I have several observations on this film that relate directly to climate change and the way that these issues are communicated.

Imagine you were part of a highly successful environmental campaign group, that had spent the best part of the last year enthusiastically building a broad coalition of organisations – from schools, to local councils, to football teams – committed to cutting their carbon footprint. How might you choose to mark such a successful 10 months?

An attention-grabbing stunt of some kind? Great idea. A controversial and challenging video? That could work, yes. A poorly executed ‘joke’ about peer pressure involving the violent deaths of children and office workers who don’t subscribe to your campaign? Err, possibly not…

But yet, bizarrely, this is precisely what the otherwise well-respected 10:10 group opted to do. If you’ve not yet seen the video No Pressure, then you can now only view bootlegged versions as the original was wisely taken down just hours after it was launched. It made the front page of the Guardian Environment section, took a predictable bashing from the far-right conspiracy theorist James Delingpole over at the Telegraph, and sent the, ahem, ‘data libertarian’ blogs into a spin.

Dive right in:

• Why positive feedback doesn’t necessarily lead to runaway warming – Positive feedback happens when the response to some change amplifies that change. For example: The Earth heats up, and some of the sea ice near the poles melts. Now bare water is exposed to the sun’s rays, and absorbs more light than did the previous ice cover; so the planet heats up a little more. In both of these cases, the “effect” reinforces the “cause”, which will increase the “effect”, which will reinforce the “cause”… So won’t this spin out of control? The answer is, No, it will not, because each subsequent stage of reinforcement & increase will be weaker and weaker. The feedback cycles will go on and on, but there will be a diminishing of returns, so that after just a few cycles, it won’t matter anymore.
• Himalayan Glaciers: Wrong Date, Right Message – Is the AR4 terribly flawed? It is important to note that this is one error in a roughly 3000 page technical document, an error percentage similar to the Encyclopedia Britannica. The 2035 claim was not included in the Technical Summary, the Summary for Policymakers, or the Synthesis Report. Does this error show the IPCC has an ‘alarmist’ bias – a tendency to exaggerate the negative impacts of climate change? In fact, there are far more documented instances of the AR4 being too conservative, rather than too alarmist, on emissions scenarios, sea level rise, and Arctic sea-ice melt. Many of the Himalayan Glaciers are retreating at an accelerating rate (Ren 2006) and roughly 500 million people depend on the melt water from these glaciers (Kehrwald 2008).
• A history of international climate change policy – An overview of the history of international climate policy over the last 30 years, divided into five periods. The article shows (1) the increasing complexity of the definition of the climate change issue from an environmental to a development issue; (2) the inability of the developed countries to reduce their own emissions and raise funds commensurate with the nature of the problem and their initial commitments; (3) the increasing engagement of different social actors in the discussion and, in particular, the gradual use of market mechanisms in the regime; (4) the increasing search for alternative solutions within the formal negotiations—such as the identification of nationally appropriate mitigation actions for the developing world, reducing emissions from deforestation and forest degradation, and the use of geo-engineering solutions; and (5) the search for solutions outside the regime—the mobilization of sub-national policies on climate change, litigation, and markets on biofuels.
• Coffee threatened by beetles in a warming world (!) – The Arabica coffee grown in Ethiopia and Latin America is an especially climate-sensitive crop. It requires just the right amount of rain and an average annual temperature between 64 degrees Fahrenheit and 70 degrees Fahrenheit to prosper. As temperatures rise — Ethiopia’s average low temperature has increased by about .66 degrees F every decade since 1951, according to the country’s National Meteorological Agency — and rains become more variable, Ethiopian coffee farmers have suffered increasingly poor yields. Last year was especially bad, with exports dropping by 33 percent. Some have moved their coffee trees to higher elevations, while others have been forced to switch to livestock and more heat-tolerant crops, such as enset, a starchy root vegetable similar to the plantain. Now, there is evidence that a warming climate may be linked to one of the major threats facing the coffee industry in Ethiopia and elsewhere…

• And yet it works. Adam Corner on ‘ClimateGate’, transparency & peer-review. – “Open access is based on the premise that there are those outside the inner circle of peer reviewers who are competent enough to provide a second opinion on the science. This is indisputably true. But while talk of throwing open the lab doors might be rhetorically satisfying, it would provide only an illusion of democracy. Certainly there are non-academics competent enough with statistics to find errors in a piece of published science. Correcting errors in science would be a valuable service for an auditor to offer. But if several auditors reached conflicting conclusions, then somehow a judgement would have to be made about their respective competence. And who should make that judgement? Presumably a group of suitably qualified, honest individuals with a proven track record in a relevant discipline – in other words, peer review.”
• Climate email inquiry: bringing democracy to science | Richard Horton – “Scientists need to do more to emphasise their uncertainties, not recoil from them. Uncertainty may be uncomfortable, but its admission builds trust. It demonstrates integrity. One of science’s great strengths is its quantification of doubt. Fourth, scientists need to take peer review off its pedestal. As an editor, I know that rigorous peer review is indispensable. But I also know that it is widely misunderstood. Peer review is not the absolute or final arbiter of scientific quality. It does not test the validity of a piece of research. It does not guarantee truth. Peer review can improve the quality of a research paper – it tells you something about the acceptability of new findings among fellow scientists – but the prevailing myths need to be debunked. We need a more realistic understanding about what peer review can do and what it can’t. If we treat peer review as a sacred academic cow, we will continue to let the public down again and again.”

• Will 2010 be the hottest year on record? – it all depends on which data source you choose: GISTEMP (likely) or HadCRU (about as likely as not).
• Climate change is leaving us with extra space junk – Even the space junk is trying to tell us we’re changing the climate. One more independent line of evidence to add to the pile, how many do we need?!
• Black Carbon’s Grey Areas – A brilliant, must-read article on black carbon. Who would have thought it has such broad geopolitical implications? Worth the effort. It’s conclusions: 1. Stop throwing cook-stoves at the problem. 2. Target diesel. 3. Be very careful about comparing black carbon with carbon dioxide.
• Ocean acidification – still happening.
• Arctic climate may be more sensitive to warming than thought – “Our findings indicate that CO2 levels of approximately 400 parts per million are sufficient to produce mean annual temperatures in the High Arctic of approximately 0 degrees Celsius (32 degrees F) [19 degrees Celsius warmer than today!],” Ballantyne said. “As temperatures approach 0 degrees Celsius, it becomes exceedingly difficult to maintain permanent sea and glacial ice in the Arctic. Thus current levels of CO2 in the atmosphere of approximately 390 parts per million may be approaching a tipping point for irreversible ice-free conditions in the Arctic.”
• Network Rail study to assess impact of climate change – eco-stealth taxes are being used to… strengthen our vulnerable rail network, oh.
• Troubling ice melt in East Antarctica – it’s losing mass, which is not good. – “It’s too early to know what the ice loss in East Antarctica really means, says Isabella Velicogna, a remote-sensing specialist at NASA’s Jet Propulsion Laboratory in Pasadena, California. “What is important is to see what’s generating the mass loss,” she says. Reductions in snowfall, for example, might reflect short-term weather cycles that could reverse at any time. But thinning caused by accelerating glaciers—as seen in West Antarctica—would warrant concern.”
• Peru inventor ‘whitewashes’ peaks to slow glacier melt – In a remote corner of the Peruvian Andes, men in paint-daubed boilersuits diligently coat a mountain summit with whitewash in an experimental bid to recuperate the country’s melting glaciers. Peru’s Environment Minister Antonio Brack has said the World Bank’s 200,000 dollars in funding would be better spent on other “projects which would have more impact in mitigating climate change.” “It’s nonsense”, he commented bluntly last year.
• Leakegate: A retraction – “It is an open question as to what impact these retractions and apologies have, but just as with technical comments on nonsense articles appearing a year after the damage was done, setting the record straight is a important for those people who will be looking at this at a later date, and gives some hope that the media can be held (a little) accountable for what they publish.”

And finally, on a slight tangent:

• Ben Goldacre: Yeah well you can prove anything with science – “When presented with unwelcome scientific evidence, it seems, in a desperate bid to retain some consistency in their world view, people would rather conclude that science in general is broken. This is an interesting finding. But I’m not sure it makes me very happy.”

Last week saw the release of three university-led nationally representative surveys on public attitudes towards climate change – two in the US (1, 2) and one in the UK. In line with previous surveys from the last few years, the UK poll shows four consistent findings:

• A large majority of people think the climate is changing (78%)
• A large majority of people are concerned about this (71%)
• A large majority support the use of tax revenue to fund low-carbon policies such as investment in renewables (68%)
• A large majority of people say they are willing to reduce the amount of energy they use in order to tackle climate change (65%)

If this doesn’t sound like the findings you saw reported, or your impression of public attitudes towards climate change, then go and look up the results which are publicly available. The picture in the US is slightly different, but not drastically so, with large majorities agreeing that climate change is happening and expressing support for developing low-carbon energy infrastructure.
