Gaia scientist Lovelock predicts planetary wipeout
LONDON (Reuters) - 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 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 adopted the name Gaia, the Greek mother earth goddess, in the 1960s to apply to his then revolutionary theory that the earth functions as a single, self-sustaining organism. His theory is now widely accepted.
