My Humble Opinion of "Global Climate Change".
1. It is either real, or it isn't. I can't think of any other options. Now if it doesn't exist there is nothing we need to do about it.
2. Climate change, if it exists, is either man made or natural or a combination. I suspect that since the polar caps are getting warmer on Mars as well that it is natural. If it is "natural" and a result of solar activity I can't think of anything we can do about it.
3. Even if we decided to tackle this problem, it cannot be done as a single country. Everyone would have go make a lot of sacrifices including China, Russia and India. We are busy trying to lock ourselves into a committment to attack this problem (which may or may not exist and may or may not have a solution). We cannot solve this problem by ourselves and any committment that requires us to make sacrifices immediately and lets others (Russia China and India) promise that they will "think about" making some sort of committment perhaps in 2035 will destroy this country.
I hope this makes sense. My vision is so bad I can't even make out my own typing.
