The Times of London writes:
The UN body that advises world leaders on climate change must investigate an apparent bias in its report that resulted in several exaggerations of the impact of global warming, according to its former chairman.
In an interview with The Times Robert Watson said that all the errors exposed so far in the report by the Intergovernmental Panel on Climate Change (IPCC) resulted in overstatements of the severity of the problem.
Professor Watson, currently chief scientific adviser to the Department for Environment, Food and Rural Affairs, said that if the errors had just been innocent mistakes, as has been claimed by the current chairman, Rajendra Pachauri, some would probably have understated the impact of climate change.
Professor Watson, who served as chairman of the IPCC from 1997-2002, said: “The mistakes all appear to have gone in the direction of making it seem like climate change is more serious by overstating the impact. That is worrying. The IPCC needs to look at this trend in the errors and ask why it happened.”
In a slap at IPCC’s scientific accuracy, Watson also suggested that the IPCC should employ graduate science students to check the sources of each claim made in its next report.
