...that we are just holding off the inevitable at this point. Global temperatures, he says, could raise as much as 8 degrees Celsius and that the best we can do is buy ourselves time...because the damage has been done, the gears of the giant mechanism are already in motion in make it happen.
The Gaia theory, from what little I have heard about it, looks at the entire earth as one living organism which can and does regulate itself.
This would be the counterpoint on the other end of the spectrum from the Global Warming Science skepticism that I posted several weeks ago.
The earth has a fever that could boost temperatures by 8 degrees Celsius making large parts of the surface uninhabitable and threatening billions of peoples' lives, a controversial climate scientist said on Tuesday.
James Lovelock, who angered climate scientists with his Gaia theory of a living planet and then alienated environmentalists by backing nuclear power, said a traumatized earth might only be able to support less than a tenth of it's 6 billion people.
"We are not all doomed. An awful lot of people will die, but I don't see the species dying out," he told a news conference. "A hot earth couldn't support much over 500 million."
"Almost all of the systems that have been looked at are in positive feedback ... and soon those effects will be larger than any of the effects of carbon dioxide emissions from industry and so on around the world," he added.
Scientists say that global warming due to carbon emissions from burning fossil fuels for power and transport could boost average temperatures by up to 6C by the end of the century causing floods, famines and violent storms.
But they also say that tough action now to cut carbon emissions could stop atmospheric concentrations of CO2 hitting 450 parts per million -- equivalent to a temperature rise of 2C from pre-industrial levels -- and save the planet.
Lovelock said temperature rises of up to 8C were already built in and while efforts to curb it were morally commendable, they were wasted.
"It is a bit like if your kidneys fail you can go on dialysis -- and who would refuse dialysis if death is the alternative. We should think of it in that context," he said.
"But remember that all they are doing is buying us time, no more. The problems go on," he added.
