The scientist behind the bogus claim in a Nobel Prize-winning UN report that Himalayan glaciers will have melted by 2035 last night admitted it was included purely to put political pressure on world leaders. Dr Murari Lal also said he was well aware the statement, in the 2007 report by the Intergovernmental Panel on Climate Change (IPCC), did not rest on peer-reviewed scientific research.
In an interview with The Mail on Sunday, Dr Lal, the co-ordinating lead author of the report’s chapter on Asia, said: ‘It related to several countries in this region and their water sources. We thought that if we can highlight it, it will impact policy-makers and politicians and encourage them to take some concrete action. ‘It had importance for the region, so we thought we should put it in.’
Dr Lal’s admission will only add to the mounting furore over the melting glaciers assertion, which the IPCC was last week forced to withdraw because it has no scientific foundation. According to the IPCC’s statement of principles, its role is ‘to assess on a comprehensive, objective, open and transparent basis, scientific, technical and socio-economic information – IPCC reports should be neutral with respect to policy’.
The claim that Himalayan glaciers are set to disappear by 2035 rests on two 1999 magazine interviews with glaciologist Syed Hasnain, which were then recycled without any further investigation in a 2005 report by the environmental campaign group WWF. It was this report that Dr Lal and his team cited as their source.
The WWF article also contained a basic error in its arithmetic. A claim that one glacier was retreating at the alarming rate of 134 metres a year should in fact have said 23 metres – the authors had divided the total loss measured over 121 years by 21, not 121. Last Friday, the WWF website posted a humiliating statement recognising the claim as ‘unsound’, and saying it ‘regrets any confusion caused’.
Dr Lal said: ‘We knew the WWF report with the 2035 date was “grey literature” [material not published in a peer-reviewed journal]. But it was never picked up by any of the authors in our working group, nor by any of the more than 500 external reviewers, by the governments to which it was sent, or by the final IPCC review editors.’
In fact, the 2035 melting date seems to have been plucked from thin air. Professor Graham Cogley, a glacier expert at Trent University in Canada, who began to raise doubts in scientific circles last year, said the claim multiplies the rate at which glaciers have been seen to melt by a factor of about 25. ‘My educated guess is that there will be somewhat less ice in 2035 than there is now,’ he said. ‘But there is no way the glaciers will be close to disappearing. It doesn’t seem to me that exaggerating the problem’s seriousness is going to help solve it.’
One of the problems bedevilling Himalayan glacier research is a lack of reliable data. But an authoritative report published last November by the Indian government said: ‘Himalayan glaciers have not in any way exhibited, especially in recent years, an abnormal annual retreat.’
When this report was issued, Raj Pachauri, the IPCC chairman, denounced it as ‘voodoo science’. Having been forced to apologise over the 2035 claim, Dr Pachauri blamed Dr Lal, saying his team had failed to apply IPCC procedures. It was an accusation rebutted angrily by Dr Lal. ‘We as authors followed them to the letter,’ he said. ‘Had we received information that undermined the claim, we would have included it.’
However, an analysis of those 500-plus formal review comments, to be published tomorrow by the Global Warming Policy Foundation (GWPF), the new body founded by former Chancellor Nigel Lawson, suggests that when reviewers did raise issues that called the claim into question, Dr Lal and his colleagues simply ignored them. For example, Hayley Fowler of Newcastle University, suggested that their draft did not mention that Himalayan glaciers in the Karakoram range are growing rapidly, citing a paper published in the influential journal Nature.
In their response, the IPCC authors said, bizarrely, that they were ‘unable to get hold of the suggested references’, but would ‘consider’ this in their final version. They failed to do so.
The Japanese government commented that the draft did not clarify what it meant by stating that the likelihood of the glaciers disappearing by 2035 was ‘very high’. ‘What is the confidence level?’ it asked. The authors’ response said ‘appropriate revisions and editing made’. But the final version was identical to their draft.
Last week, Professor Georg Kaser, a glacier expert from Austria, who was lead author of a different chapter in the IPCC report, said when he became aware of the 2035 claim a few months before the report was published, he wrote to Dr Lal, urging him to withdraw it as patently untrue. Dr Lal claimed he never received this letter. ‘He didn’t contact me or any of the other authors of the chapter,’ he said.
The damage to the IPCC’s reputation, already tarnished by last year’s ‘Warmergate’ leaked email scandal, is likely to be considerable. Benny Peiser, the GWPF’s director, said the affair suggested the IPCC review process was ‘skewed by a bias towards alarmist assessments’.
Environmentalist Alton Byers said the panel’s credibility had been damaged. ‘They’ve done sloppy work,’ he said. ‘We need better research on the ground, not unreliable predictions derived from computer models.’
Last night, Dr Pachauri defended the IPCC, saying it was wrong to generalise based on a single mistake. ‘Our procedure is robust,’ he added.
This blog is a about Anthropogenic Global Warming(AGW) which is global warming caused by the activities of man. The core issues are:
- Is the climate warming, - Is the warming outside of historic norms - Is it caused by anthropogenic CO2 - Will it result in global disaster as the IPCC insists
Only the first has been satisfactorily answered in part and the qualification is that the data upon which the IPCC claims are based has not been made available for full scrutiny as yet. The average terrestrial land temperature experienced slight warming this century. In some regions such as Antarctica it has cooled. The earth has been recovering from the Little Ice Age since 1650 (see Akasofu 2007 & 2009) which is one reason this warming trend is expected. It appears that this is not outside of historic norms (see Medieval Warm Period) and that the IPCC and some scientists have attempted to downplay the Medieval Warm Period and the effects of the Little Ice Age. The later two issues are not settled despite UN and government spin towards the contrary. For some excellent background from a real climatologist not implicated in the recent CRU revelations see the links to Dr Roy Spencer's blog below who discusses these issues as a professional.

Glenn Reynolds (USA - Instapundit.com): "I'll believe its a crisis when the people who tell me it's a crisis start acting like it's a crisis."
Nick himself (Counting Cats in Zanzibar blog): "Is it just me or has the spam-trade been entirely taken-over by performance poets on Arts-Council grants?"
Dr. Kiminori Itoh (Phd UN IPCC Scientist Award-winning environmental physical chemist): "When people know what the truth is the will feel deceived by science and scientists."
Dr. Stephen Schneider (Stanford professor of climatology, Lead author on many IPCC reports, in an interview with Discover Magazine 1989): "We have to offer up scary scenarios, make simplified, dramatic statements, and make little mention of any doubts we may have. Each of us has to decide what the right balance is between being effective and being honest."
Former US Vice President Al Gore (now, chairman and co-founder of Generation Investment Management- a London-based business that sells carbon credits, in an interview with Grist Magazine 9 May 2006 re his book An Inconvenient Truth) "Nobody is interested in solutions if they don't think there's a problem. Given that starting point, I believe it is appropriate to have an over-representation of factual presentations on how dangerous (global warming) is, as a predicate for opening up the audience to listen to what the solutions are..."
