The Revenge of Gaia - James Lovelock

Thirty years ago, the scientist James Lovelock worked out that the Earth possessed a planetary-scale control system which kept the environment fit for life. He called it Gaia, and the theory has become widely accepted. Now, he believes mankind's abuse of the environment is making that mechanism work against us. His astonishing conclusion - that climate change is already insoluble, and life on Earth will never be the same again.

In a profoundly pessimistic new assessment, published in today's Independent, Professor Lovelock suggests that efforts to counter global warming cannot succeed, and that, in effect, it is already too late.

The world and human society face disaster to a worse extent, and on a faster timescale, than almost anybody realises, he believes. He writes: " Before this century is over, billions of us will die, and the few breeding pairs of people that survive will be in the Arctic where the climate remains tolerable."

He terms this phenomenon "The Revenge of Gaia" and examines it in detail in a new book with that title, to be published next month.

In his book's concluding chapter, he writes: "What should a sensible European government be doing now? I think we have little option but to prepare for the worst, and assume that we have passed the threshold."
And in today's Independent he writes: "We will do our best to survive, but sadly I cannot see the United States or the emerging economies of China and India cutting back in time, and they are the main source of [CO2] emissions. The worst will happen ..."

As soon as you pump up the temperature, everything changes. And at the moment the system is amplifying change. "So our problem is that anything we do, like increasing the carbon dioxide, mucking about with the land, destroying forests, farming too much, things like that - they don't just produce a linear increase in temperature, they produce an amplified increase in temperature.

"The analogy I use is, it's as if we were in a pleasure boat above the Niagara Falls. You're all right as long as the engines are going, and you can get out of it. But if the engines fail, you're drawn towards the edge faster and faster, and there's no hope of getting back once you've gone over - then you're going down.

"And the uprise is just like that, the steep jump of temperature on Earth. It is exactly like the drop in the Falls."
