Rather than responding reflexively and without thought, why not examine the facts underlying their claims and draw your own conclusions. Then we'd have something to debate about. The evidence for global warming is pretty strong. However, much of that same evidence seems to suggest that, while it may indeed be our collective "fault", it may be beyond our collective power to control. For all the blame on Bush, this is a phenomenon that took decades and the collective behavior of billions of people to build up, and convincing billions of people to give up the "lifestyles of the rich and famous" and settle for less - when a heck of a lot of them are just now finding the good life within their reach - is one hell of a difficult geopolitical hurdle to make.

Our best bet, as DW points out, might be some combination of technological solutions, although some of his ideas are pretty close to impossible just on scale. However, we've made significant technological advances over the past few decades and are likely to continue to make significant advances. The emerging nations pursuing their own paths to success will have different priorities once they've achieved their immediate goals, and by then we'll have tested out the alternatives and identified the best options, making their paths toward change cheaper and easier.
