Climate Change

My hon. Friend asks a question. May I respond in the form of a question? Does he not realise that most medical research is conducted on precisely that sort of statistical basis, in that a product that has only a small chance of causing cancer goes into the public domain, whereas we legislate against products that have a large chance of doing so? I think that global warming is likely to cause lukewarming, not serious problems. My hon. Friend asks whether I would raise concerns about cancer on a statistical basis in other spheres. Indeed, I have done so: I argued in favour of the legalisation of cannabis, because the chance of getting cancer from cannabis is negligible, while the chance of getting the disease from tobacco is very great.
