Why are the world’s governments bothering? Why are they jetting to Cancun next week to discuss what to do now about global warming? The vogue has passed. The fad has faded. Global warming is yesterday’s apocalypse. Didn’t somebody leak an email that showed it was all made up? Doesn’t it sometimes snow in the winter? Didn’t Al Gore get fat, or something? Alas, the biosphere doesn’t read Vogue. Nobody thought to tell it that global warming is so 2007. All it knows is three facts. 2010 is globally the hottest year since records began. 2010 is the year humanity’s emissions of planet-warming gases reached its highest level ever. And exactly as the climate scientists predicted, we are seeing a rapid increase in catastrophic weather events, from the choking of Moscow by gigantic unprecedented forest fires to the drowning of one quarter of Pakistan.
