Professor James Lovelock, the scientist who developed Gaia theory, has said it is too late to try and save the planet. The man who achieved global fame for his theory that the whole earth is a single organism now believes that we can only hope that the earth will take care of itself in the face of completely unpredictable climate change. Interviewed by BBC Today presenter John Humphrys, he said that while the earth's future was utterly uncertain, mankind was not aware it had "pulled the trigger" on global warming as it built its civilizations.

'We're not really guilty. We didn't deliberately set out to heat the world' What is more, he predicts, the earth's climate will not conveniently comply with the models of modern climate scientists. As the record winter cold testifies, he says, global temperatures move in "jerks and jumps", and we cannot confidently predict what the future holds. 'The world doesn't change its climate conveniently'
Prof Lovelock does not pull his punches on the politicians and scientists who are set to gain from the idea that we can predict climate change and save the planet ourselves. Scientists, he says, have moved from investigating nature as a vocation, to being caught in a career path where it makes sense to "fudge the data". 'Science has changed in our lifetime'

And while renewable energy technology may make good business sense, he says, it is not based on "good practical engineering". Renewable technology 'doesn't really work'
At the age of 90, Prof Lovelock is resigned to his own fate and the fate of the planet. Whether the planet saves itself or not, he argues, all we can do is to "enjoy life while you can".

If you’re interested here’s the science...it makes sense if you think of the earth itself as the highest form of life within the planet.
The Gaia hypothesis or Gaia principle is an ecological hypothesis proposing that the biosphere and the physical components of the Earth (atmosphere, cryosphere, hydrosphere and lithosphere) are closely integrated to form a complex interacting system that maintains the climatic and biogeochemical conditions on Earth in a preferred homeostasis. Originally proposed by James Lovelock as the earth feedback hypothesis, it was named the Gaia Hypothesis after the Greek primordial goddess of the Earth, at the suggestion of William Golding, Nobel prize-winner in literature and friend and neighbour of Lovelock. The hypothesis is frequently described as viewing the Earth as a single organism. Lovelock and other supporters of the idea now call it Gaia theory, regarding it as a scientific theory and not mere hypothesis, since they believe it has passed predictive tests.
