What has changed dramatically, however, is his position on climate change. He now says: “Anyone who tries to predict more than five to 10 years is a bit of an idiot, because so many things can change unexpectedly.” But isn’t that exactly what he did last time we met? “I know,” he grins teasingly. “ But I’ve grown up a bit since then. ”
Lovelock now believes that “ CO2 is going up, but nowhere near as fast as they thought it would. The computer models just weren’t reliable. In fact, ” he goes on breezily, “ I’m not sure the whole thing isn’t crazy, this climate change. You’ve only got to look at Singapore. It’s two-and-a-half times higher than the worst-case scenario for climate change, and it’s one of the most desirable cities in the world to live in. ”
There are various possible explanations for his change of heart. One is that Lovelock is right, and the models on which his former predictions were based were fatally flawed. Another is that his iconoclastic sensibility made revision irresistible. An incorrigible subversive, Lovelock was warning the world about climate change for decades before it began to pay attention, and just when the scientific consensus began to call for intervention to prevent it, he decided we were already too late. But there is a third explanation for why he has shifted his position again, and nowadays feels “laid back about climate change”. All things being equal – “and it’s only got to take one sizable volcano to erupt and all the models, everything else, is right off the board” – he expects that before the consequences of global warming can impact on us significantly, something else will have made our world unrecognizable, and threaten the human race.
