Claims Himalayan glaciers could melt by 2035 were false, says UN scientist
> IPCC report said ice would vanish 'perhaps sooner'
> Panel head apologises for unsubstantiated assertion

One paragraph, buried in 3,000 pages of reports and published almost three years ago, has humbled the head of the UN's Intergovernmental Panel on Climate Change. Facing global outcry, Rajendra Pachauri backed down and apologised today for a disputed IPCC claim that there was a very high chance the Himalayan glaciers would melt away by 2035.

The assertion, now discredited, was included in the most recent IPCC report assessing climate change science, ­published in 2007. Those reports are widely credited with convincing the world that human activity was causing global warming.

But Pachauri admitted in an IPCC statement (pdf) that in this case "the clear and well-established standards of evidence required by the IPCC procedures were not applied properly", and "poorly substantiated estimates" of the speed of glacier melting had made it into print.

He had stridently defended the report in recent months. Furthermore, the Guardian has discovered the claim was questioned by the Japanese government before publication, and by other scientists.

Pachauri's statement is a reprimand for some IPCC ­scientists involved. It is also bound to encourage critics of the panel to redouble efforts to undermine its scientific reputation. However, many scientists say evidence for man-made climate change remains compelling and note that the 2035 claim did not appear in the more widely read "summary for policymakers".

The offending paragraph, in the panel's fourth assessment report on the impacts of climate change, said: "Glaciers in the Himalaya are receding faster than in any other part of the world and, if the present rate continues, the likelihood of them disappearing by the year 2035 and perhaps sooner is very high."

In IPCC terminology a "very high" likelihood has a specific meaning: more than a 90% chance of coming true.

The report's only quoted source for the claim was a 2005 campaigning report from the environment group WWF. In turn, the WWF report's only source was remarks made in 1999 by a leading Indian glaciologist, Syed Hasnain, then vice-chancellor of Jawaharlal Nehru University in Delhi, to journalists at two magazines, New Scientist in London, and Down to Earth in New Delhi.

Hasnain had never submitted the suggestion of such an early demise to a scientific journal because, he said last week, it had always been "speculative". How this made it to the august pages of the IPCC report remains unclear. But the IPCC text is almost identical to that in the Down to Earth article in April 1999. WWF said today it regretted "any confusion caused" and would amend its report. The panel is yet to make a similar commitment.

Hasnain is currently employed as a senior fellow at an Indian research institute, the Tata Energy Research Institute, whose director is Pachauri.

Glaciologists who spoke to the Guardian say Himalayan glaciers contain so much ice it will be 300 years before it vanishes.

The affair raises serious questions about the rigour of the IPCC's process of sifting and assessing the thousands of research findings it includes in its reports. It also raises questions about the competence of Pachauri, who angrily defended the report's conclusions about Himalayan glaciers after they were called "alarmist" last autumn by India's environment minister, Jairam Ramesh.

Pachauri accused Ramesh of relying on "voodoo science", called the minister "extremely arrogant" and said Ramesh's claims were "not peer reviewed". It is now clear that it was the panel's claims that were not reviewed. The author of the part of the panel's report, another Indian glaciologist, Murari Lal, last week defended inclusion of 2035, saying "the error if any lies with Dr Hasnain's assertion".

Pachauri's statement repudiates that position. He said he "regrets the poor application of well-established IPCC procedures in this instance". One person who has not spoken is the co-chairman of the impacts assessment report, Martin Parry, who was unavailable for comment. But his successor, Chris Field of the Carnegie Institution in Stanford, California, said it was a powerful reminder of "carefully applying the well-established IPCC principles to every statement in every paragraph".

"Glaciergate" has brought into the open splits between authors of the four different IPCC reports, produced every five or so years. However, Bob Ward, policy director at the Grantham Research Institute on Climate Change at the LSE, said: "We should be cautious about making sweeping ­statements about the IPCC based on a single error."


[Environment > Climate change]
UN drops deadline for countries to state climate change targets
Copenhagen deal falters as just 20 countries of 192 sign up to declare their global warming strategies

The UN has dropped the 31 January deadline by which time all countries were expected to officially state their emission reduction targets or list the actions they planned to take to counter climate change.

Yvo de Boer, UN climate change chief, today changed the original date set at last month's fractious Copenhagen climate summit, saying that it was now a "soft" deadline, which countries could sign up to when they chose. "I do not expect everyone to meet the deadline. Countries are not being asked if they want to adhere… but to indicate if they want to be associated [with the Copenhagen accord].

"I see the accord as a living document that tracks actions that countries want to take," he told journalists in Bonn.

"It's a soft deadline. Countries are not being asked to sign the accord to take on legally binding targets, only to indicate their intention," he said.

The deadline was intended to be the first test of the "Copenhagen accord", the weak, three-page document that emerged at the end of the summit, and which fell far short of original expectations. It seeks to bind all countries to a goal of limiting warming to no more than 2C above pre-industrial times and proposes that $100bn a year be provided for poor countries to reduce emissions and adapt to climate change after 2020.

But with just 10 days to go, only 20 countries out of 192 have signed up, with many clearly unready or unwilling to put their name to the document. Countries which have signed so far include India, Russia, Mexico, Australia, France and Norway.

De Boer also endorsed the controversial idea of short-circuiting the traditional UN negotiating process of reaching agreement between all countries by consensus. Instead, he argued that a smaller group of countries could negotiate a climate agreement on behalf of the many.

"You cannot have 192 countries involved in discussing all the details. You cannot have all countries all of the time in one room. You do have to safeguard transparency by allowing countries to decide if they want to be represented by others, and that if a debate is advanced then the conclusion is brought back to the larger community", he said.

However, this more exclusive method of reaching agreement was criticised by some in Copenhagen after the host government, Denmark, convened a meeting of 26 world leaders in the last two days of the conference to try to reach agreement on behalf of everyone.

Critics argued that this was not only illegal, but undermined negotiations already taking place among the 192 countries and threatened the UN's multilateral and democratic process.

"The selected leaders were given a draft document that mainly represented the developed countries' positions, thereby marginalising the developing countries' views tabled at the two-year negotiations. The attempt by the Danish presidency to override the legitimate multilateral process was the reason why Copenhagen will be considered a disaster," said Martin Khor, director of the South Centre, an intergovernmental think tank for developing countries based in Geneva.

The US and Britain have argued since the conference that climate negotiations are best served by meetings of the world's largest polluters, such as China, the US, India, Brazil and South Africa. These countries, which emit more than 80% of global emissions, signed up to a deal in the final hours of the summit.

Brazil, India, China and South Africa, known as the "BASIC" group, meet next week in Delhi to agree a common position ahead of further UN climate talks.
