Stewards of the earth, a good expression. Cleaning the environment a good idea even if you don't believe in man made Global Warming. If you do believe in  man made GW and think it going to get very bad whatever we do, we should act so it doesn't get even worse.

For a number of reasons, I believe 2008 will be a watershed year for the global warming debate. The arch denier will leave office, scientists will have had more time to study the results from the Calipso sattelite and the summer Arctic Ice melt picture will be a lot clearer.

Many on both sides of the arguement have made clear predictions for 2008.
