Global Warming in the United States???

In Slate.com there was a cartoon that indicated the lack of US cooperation with the Global Warming issue.  With Al Gore’s campaign for the “Inconvenient Truth” that he has been doing in the past few years, you would think that the prospect of US’s involvement with the global warming issues would be higher.  What this cartoon fails to portray is the thought of what cooperation is being had by the other countries in this world.  I wonder what that would actually look like????
