While Gaia hypothesis has had it's critics it was a model that helped facilitate my understanding of complex interactions like the carbon cycle, so it is with interest that I note of Lovelock's predictions in his new book The Revenge of Gaia. Predictions based on his assertion that the feedback mechanisms that are used to cool the earth are now working to amplify anthropogenic warming from our CO2 emissions:
- by 2100 Europe and southern Australia would be 8 degrees hotter than they are today
- he 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
- he predicts efforts to slow it may already be doomed
- 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 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.
