From the Guardian, where I find it surprising they actually printed it:
Scientist behind the Gaia hypothesis says environment movement does not pay enough attention to facts and he was too certain in the past about rising temperatures
Environmentalism has “become a religion” and does not pay enough attention to facts, according to James Lovelock.
The 94 year-old scientist, famous for his Gaia hypothesis that Earth is a self-regulating, single organism, also said that he had been too certain about the rate of global warming in his past book, that “it’s just as silly to be a [climate] denier as it is to be a believer” and that fracking and nuclear power should power the UK, not renewable sources such as windfarms.
Speaking to the Guardian for an interview ahead of a landmark UN climate science report on Monday on the impacts of climate change, Lovelock said of the warnings of climate catastrophe in his 2006 book, Revenge of Gaia: “I was a little too certain in that book. You just can’t tell what’s going to happen.”
Lovelock’s comments appear to be at odds with dire forecasts from a report by the Intergovernmental Panel on Climate Change on Monday, which leaked versions show will warn that even small temperature rises will bring “abrupt and irreversible changes” to natural systems, including Arctic sea ice and coral reefs.
Asked if his remarks would give ammunition to climate change sceptics, he said: “It’s just as silly to be a denier as it is to be a believer. You can’t be certain.”
