Lord Stern: I Should Have Been Fiercer in Climate Change Review

Stern says things have moved on in the eight years since his review.  "I would have been much fiercer", he says.  "Emissions have gone up faster than I thought, and some of the effects of global warming are coming through more quickly, such as melting of the glaciers and the polar ice caps.  But technical change has been faster too."

Stern says that on present trends global temperatures will be 4-5C higher in the next century and governments are fooling themselves if they think this will only have a modest impact on their economies.

"The last time we had a change in global temperatures of this order of magnitude it was in the other direction.  It was called the Ice Age."
