I know that there is a debate about [humans causing the warming of the planet] – that’s all I am prepared to say. I’m not a scientist but when someone tells me that all the scientists agree, I say no they don’t. They all agree that there’s a tendency for human emissions to heat the planet, but whether that’s responsible for all the heating is an open question. But I must say that once it was confidently predicted that there was run away warming and now we have had a pause for 16 years. Now please explain that.
