The Second Hit on the IPCC report
The Sunday Times has since found that the scientific paper on which the IPCC based its claim had not been peer reviewed, nor published, at the time the climate body issued its report.
When the paper was eventually published, in 2008, it had a new caveat. It said: "We find insufficient evidence to claim a statistical relationship between global temperature increase and catastrophe losses."
Despite this change the IPCC did not issue a clarification ahead of the Copenhagen climate summit last month. It has also emerged that at least two scientific reviewers who checked drafts of the IPCC report urged greater caution in proposing a link between climate change and disaster impacts — but were ignored.
Mike Hulme, professor of climate change at the Tyndall Centre, which advises the UK government on global warming, said there was no real evidence that natural disasters were already being made worse by climate change. He said: “A proper analysis shows that these claims are usually superficial”
Such warnings may prove uncomfortable for Miliband whose recent speeches have often linked climate change with disasters such as the floods that recently hit Bangladesh and Cumbria. Last month he said: “We must not let the sceptics pass off political opinion as scientific fact. Events in Cumbria give a foretaste of the kind of weather runaway climate change could bring. Abroad, the melting of the Himalayan glaciers that feed the great rivers of South Asia could put hundreds of millions of people at risk of drought. Our security is at stake.”
