Paper 'studies glacier length data available worldwide since 1800 and finds that glaciers retreated faster during the first half of the 20th century than the second half from 1950-2000. This is the opposite pattern that would be expected if man-made greenhouse gases were the cause, and suggests a natural origin. Most warmists and the IPCC claim man-made greenhouse gases did not begin to affect climate until after 1950, and thus can't be blamed for the fastest rate of glacier retreat from ~1850-1950 and subsequentdeceleration.'
Nature question: 'Is climate change going to be less extreme than you previously thought?'
Lovelock: The Revenge of Gaia was over the top, but we were all so taken in by the perfect correlation between temperature and CO2 in the ice-core analyses [from the ice-sheets of Greenland and Antarctica, studied since the 1980s]. You could draw a straight line relating temperature and CO2, and it was such a temptation for everyone to say, “Well, with CO2 rising we can say in such and such a year it will be this hot.” It was a mistake we all made.
We shouldn’t have forgotten that the system has a lot of inertia and we’re not going to shift it very quickly. The thing we’ve all forgotten is the heat storage of the ocean — it’s a thousand times greater than the atmosphere and the surface. You can’t change that very rapidly But being an independent scientist, it is much easier to say you made a mistake than if you are a government department or an employee or anything like that.
Nature: 'So what will the next 100 years look like?'
Lovelock: 'That’s impossible to answer. All I can say is that it will be nowhere as near as bad as the worst-case scenario.'
'The tipping point for Farley (Hayhoe's husband)? When the two went to the NASA website, downloaded global temperature data, and plotted it on their own computer. “It was clearly going up,” Hayhoe said, so “he had to decide, was NASA, the organization that put people on the moon, involved in some worldwide massive hoax or were they telling the truth?”
