Anyone following the recent string of articles in the mainstream press attacking the UN’s Intergovernmental Panel on Climate Change (IPCC) may have entertained a sneaking suspicion that the hidden hand of the climate denial lobby was at work behind many of them. That suspicion, it turns out, is exactly right – the fingerprints of the deniers are all over several of the key stories.
This latest feeding frenzy kicked off when one erroneous claim – that Himalayan glaciers were “very likely” to disappear by 2035 – was found to have slipped through the net, the IPCC’s extensive review process having failed to weed it out prior to publication. The claim was included on page 493 of the IPCC’s second 1000-page Working Group report on “Impacts, Adaptation and Vulnerability” (WGII). The reference given was to a WWF report – part of the non-peer-reviewed “grey literature” that makes up a periphery of the material in the second Working Group’s report.
Marginal as it may have been, for the media this isolated error appears to have opened the floodgates. A hysterical flurry of activity followed, as the denial lobby began trawling through the IPCC report for anything else that might look bad – particularly anything referencing the grey literature. The results of this search were then fed to elements of the press, who eagerly snatched them up – uncritically repeating many of their claims in the process.
A majority of the world’s nations yesterday signed up to the Copenhagen Accord and filed plans for emissions reductions, scraping over the UN deadline of 31st January for doing so. But the pledged actions fall far short of action needed to prevent global temperatures rising by 2 degrees C – the target adopted in the text of the Accord itself.
Instead, existing actions set the world on course for a 3.5 degrees Celsius temperature rise, according to earlier analysis of pledges carried out by consultancy Ecofys. PriceWaterhouseCoopers calculate that on current projections the world will burn up its allocated carbon budget for the first half of the century by 2034 – 16 years ahead of schedule.
This year, the modern environmental movement turns 40. Earth Day in 1970 marked the first mass environmental protest, and whilst some ecological ideas have a much older pedigree, it is only during the past four decades that they have attracted mainstream attention. As the disappointment of the Copenhagen climate talks sinks in, it is easy to be pessimistic about the future of environmentalism. But I would argue that, taking the longer-term perspective, it is still very much in the ascendant.
The “Glaciergate” story is about a claim in the 2007 IPCC report that the Himalayan glaciers would melt by 2035. It turns out that the evidence for this claim was from a speculative comment made by a not-very-prominent glaciologist in New Scientist in 1999. The Times and The Express have gone to town with this story claiming that it undermines the whole of the IPCC.

It is an increasingly familiar formula – a climate poll is released, the results are interpreted and analysed, and both sides claim victory. The initial analyses are inevitably the ones that scream ‘controversy’, while more considered accounts emerge at a later date. But while the polls may tell us something about public opinion, what do they tell us about climate change? Read more
Following the UEA email hack, it’s become part of the media narrative that opinion is turning against man-made global warming. It’s usually worth checking any such media claim about changes in public opinion that have supposedly occurred following a series of news stories, particularly ‘dramatic revelations’. Read more
In the wake of the “Climategate” affair – the illegal hacking and publication of a huge number of emails from the University of East Anglia’s Climatic Research Unit – I’ve been trying to put together some “points to remember” on the episode, along with some of the key points of evidence. Below is what I’ve managed to come up with. Owing to the story’s media profile, the volume of material out there is now pretty enormous and somewhat unwieldy. Nevertheless, I hope this at least begins to cover most the bases, and will generally be of some use. Read more
Following the announcement of the Copenhagen Accord, John Sauven, executive director of Greenpeace UK, declared Copenhagen “a crime scene”, with the world leaders who brokered the deal “guilty men and women.” Every crime scene demands a post-mortem, and in this entry, I”ll attempt to file a first report. I”ll warn you now: some scenes may disturb. Read more
Keep an eye on the Climate Scoreboard during the next two weeks… Note the dark blue curve in the graphic, this is the probability distribution, it shows the full range of temperature rise the current national emissions proposals would likely give rise to. Currently it’s 2-6 degrees with 3.8 degrees is the most likely outcome (according to their analysis, climate sensitivity etc.).
With my risk managers hat on, it’s hard not to notice that we could go way above 3.8 degrees… it looks like there’s a 5-10% of going over 5 degrees… the sting’s in the tail as they say!
