Portugese Desert

Reuters reports that parts of southern Portugal could become desert if global warming continues in the next few decades. Global warming is a serious problem and the U.S. should rejoin Kyoto. Even if the U.S. doesn't like the treaty, rejoining talks would allow us to start complying with the standards and provide us a seat at the table for negotiating the post-2012 protocol. Otherwise, there won't be a credible enough target for carbon emission reduction.
