How carbon gases ‘have saved us from a new ice age’

Dr Lovelock’s comments come in the wake of the scandal at the University of East Anglia where leaked emails suggested climate change data had been manipulated.

The 90-year-old British scientist, who has worked for Nasa and paved the way for the detection of man-made aerosol and refrigerant gases in the atmosphere, called for greater caution in climate research.

He compared the recent controversy to the “wildly inaccurate” early work on aerosol gases and their alleged role in depletion of the ozone layer.

He said: “Quite often, observations done by hand are accurate but all the theoretical stuff in between tends to be very dodgy and I think they are seeing this with climate change. We haven’t learned the lessons of the ozone-hole debate. It’s important to know just how much you have got to be careful.”

According to Dr Lovelock’s Gaia theory, the earth is capable of curing itself. “A planet that is effectively alive can regulate itself and its composition and climate,” he said.

Thomas Crowley, professor of geoscience at Edinburgh University, responded: “People have thought about the possibility of an ice age but it wouldn’t be for many thousands of years.

“Dr Lovelock might be right in the abstract but this does not necessarily mean that CO2 is good now.”
