Slowly and mostly unnoticed by the major news media, the air has been going out of the global warming balloon. Global temperatures stopped rising a few years ago, much to the dismay of the climate campaigners. The U.N.’s upcoming Copenhagen conference–which was supposed to yield a binding greenhouse gas emissions reduction treaty as a successor to the failed Kyoto Protocol–collapsed weeks in advance and remains on life support pending Obama’s magical intervention. Cap and trade legislation is stalled on Capitol Hill. Recent opinion polls from Gallup, Pew, Rasmussen, ABC/Washington Post, and other pollsters all find a dramatic decline in public belief in human-caused global warming. The climate campaigners continue to insist this is because they have a “communications” problem, but after Al Gore’s Nobel Prize/Academy Award double play, millions of dollars in paid advertising, and the relentless doom-mongering from the media echo chamber and the political class, this excuse is preposterous. And now the climate campaign is having its Emperor’s New Clothes moment.
