The Great Kerry Debate. The New Republic has asked me and my former Phoenix colleague Jon Keller, of WLVI-TV (Channel 56) and Boston magazine, to debate the merits of John Kerry's candidacy. I get to go first, so have a look.

According to the piece, by scientist William Calvin, the localized effects of global warming could be catastrophic. For instance, warming could halt the northward flow of the Gulf Stream, making Northern Europe as cold as Labrador.
