I'm not particularly surprised scientists who doubt that global warming is caused by human activity are being threatened. They are, after all, going after one of the most sacred of leftist cows. What is interesting is how widely these sorts of things are being reported. Could it be that, after Al Gore's triumph, the media have decided in their famously contrary way to foment a backlash? Could it simply be that those of us who have our doubts are now officially sick and tired of it, and are not taking it anymore? Are the cow-eyed idealistic college students who drove most of this finally becoming grizzled, disappointed cynics like the rest of us?
