I would say that this would be a bad move for JM. Treaties almost always hurt the US. Besides whatever is causing GW here on earth is also causing climate change on Jupiter and Mars. What kind of treaty would you propose to help our other planets in the solar system? Can there be a Jupiter tax and Mars Tax too? Maybe we can petition the Sun to quit being so hot so the temp can go back down a whole 1/2 degree.

No this is a stupid move for ANYONE to make. In the longrun environmental solutions will be found in the private sector as it advances in technology naturally. Consumers who are becoming increasingly environmentally concious will demand more from the companies they buy from and eventually get cleaner producs and a cleaner environment.

Signing a treaty would make that VERY difficult to achieve in reality.
