Al Gore’s “consensus” is about to be holed below the water-line – and those still aboard the SS Global Warming are adjusting their positions. Some, such as scientist Judith Curry of Georgia Tech, have abandoned ship. She describes the IPCC’s stance as “incomprehensible”. Others, such as the EU’s Climate Commissioner, Connie Hedegaard, steam on oblivious. Interviewed last week by the Telegraph’s Bruno Waterfield, she said: “Let’s say that science, some decades from now, said: ‘We were wrong, it was not about climate’, would it not in any case have been good to do many of the things you have to do in order to combat climate change?” If she means needlessly driving up energy prices, carpeting the countryside with wind turbines and terrifying children about a problem that turns out to have been imaginary, then most of us would probably answer “No”.
