We can hurt our economy across the board, but help some nitch market in pollution control equipment... Gee that sure sound like a good trade to me...
The problem is, we signed it and if countries that emit 55% of the emissions ratify it, we're obligated to abide by it.
If Russia signs it (and Putin is pushing it now) that puts it over 55%.
Bush told them to take a hike about ratifying it but that doesn't let us off the hook.
We should have unsigned it (post #3) but we didn't.
Perhaps someone else has a better understanding of this than I do and could explain if and where I'm wrong.
