The Revenge of Gaia

THE world has already passed the point of no return on global warming, and efforts to slow it may already be doomed, one of Britain's best-known environmentalists says.

In what The Independent described as the bleakest assessment yet of the effects of climate change by a leading scientist, Professor James Lovelock said billions would die by the end of the century, and civilisation as it is known would be unlikely to survive.

"The few breeding pairs of people that survive will be in the Arctic, where the climate remains tolerable," Professor Lovelock wrote in the newspaper.

Professor Lovelock, who in the 1970s coined the Gaia thesis that the Earth was a single organism, called on governments to start making preparations for a "hell of a climate," in which by 2100 Europe and southern Australia would be 8 degrees hotter than they are today.

The scientist makes his predictions in a new book, The Revenge of Gaia, which argues that the feedback mechanisms that used to keep the Earth cooler than it would otherwise be are now working to amplify warming caused by human CO 2 emissions.

"Sadly I cannot see the United States or the economies of China and India cutting back in time and they are the main source of CO 2 emissions."

Professor Lovelock is a controversial but respected scientist who gave a briefing on global warming in 1989 to the then prime minister, Margaret Thatcher. Two years ago he caused a furore in the environment movement by urging greens to embrace nuclear power to reduce global warming gases.
