I think some of this is becoming more and more academic, if I may.
Within the United States there are significant changes in motion. You only have to look at the number of bills before the House and Senate in the U.S. You only have to look at the actions that have been taken by many of the states. You only have to look at some of the things that have already been done by large industrial conglomerates in the United States.
The tide is clearly changing in the U.S. I think if we don't pay attention to this, we could find ourselves on the wrong side.
If you look at India and China, yes, I know the rhetoric, I've heard it for 15 years. But if you go behind that and into China and into India and see what's actually happening there, they are moving as well. The Chinese are very concerned because of water availability. They understand the threats to them from climate change and they're making some changes--and the Indians, likewise, because of energy security.
My sense, just listening and reading around, and talking to colleagues in those parts of the world, is that increasingly more and more countries are saying yes, we need to be on board, we need to do something. It won't always be the same thing, and it may not be through a global regime, but I think we shouldn't worry about what is somebody else going to do. I think if we prevaricate and delay, we may find ourselves at a crucial point simply on the wrong side of this issue.
