...I think that the goals that President Obama will announce are reasonable in terms of ambition for 2020, exceedingly ambitious for 2050, but I also think that if the western Europeans had wanted this deal, they could have gotten it under the Bush Administration or even under Clinton, but if President Obama goes and says "look, we're not going to break our economy over this," they might listen to him and that will be progress...I remember, in June of 2001 in the Rose Garden, President Bush said, "we know that there's global warming or climate change, and we know that it is largely caused by humans"...Because [Bush] declined to go forward with Kyoto, which was ultimately the right thing to do because the major economies like China and India weren't at the table, he worked to get them at the table and now this meeting is the next logical step in that process.Wow, and all that time I thought that Bush was bad on environmental issues. Thank you, Dana Perino, for setting me straight! (snark)
