All sorts of remarks are made, and the fact that they are not disputed is not necessarily a reason to set in motion quite expensive and complicated studies. From the advice which I have, I feel that this is not a project on which we ought now to embark. I only have reports of what was said, but he said that if there were 2,000 atomic bombs exploded in the next ten years it would be the beginning of the ice age. We had very bad weather last winter, but I do not think that it was due to any explosions of atomic bombs. I have some information which the hon. Member may like to have: at any one time in the tropics there are said to be between 1,000 and 2,000 thunderstorms going on, each releasing the same energy as a megaton bomb.
