One of the government’s most senior scientific advisers has said that efforts to stop a sharp rise in global temperatures were now “unrealistic”.
Prof Sir Bob Watson said that any hope of restricting the average temperature rise to 2C was “out the window”.
He said that the rise could be as high as 5C – with dire consequences…
He said: “I have to look back on [the outcome of successive climate change summits] Copenhagen, Cancun and Durban and say that I can’t be overly optimistic.
“To be quite candid the idea of a 2C target is largely out of the window.”…
“If we carry on the way we are there is a 50-50 chance that we will get to a three-degree rise,” he said.
“I wouldn’t rule out a five-degree world and that would be quite serious for the people of the world, especially the poorest. We need more political will than we currently have.”
