I have a theoretical question. With the last report it became crystal clear that the debate over science is--well, it's not over, but basically the conclusion is clear that there is a major human component to creating global warming and climate change. At what point over the years would a moderate individual--not someone on the left or totally on the right, but a moderate, open-minded individual--conclude that the evidence that we had a problem was clear enough?
It seems to me that many politicians waited until two weeks ago to say that the science was in and they agreed. As a matter of fact, many MPs in the House were apparently not allowed to comment on the science until three weeks ago. Given your experience, at what point would an enlightened, moderate political leader say that we had a problem and we had to do something about it?
