Professor Myles Allen:

I fortunately had a chance to chat to Professor Peter Thorne of the Climate Change Advisory Council, and he can confirm that they absolutely can do that. It is a matter of simply raising those numbers, which they can produce into the national conversation. I must emphasise that this warming impact calculation is not complicated at all. I take the Deputy's point about not liking scientists making things complicated. He is looking here at a scientist who is desperately trying to make things simple. This one is simple. One just calculates the warming impact of activities on global temperature. A lot of the animosity should be diffused from this debate.
