Robert Samuelson has a great column on the global warming issue in today's Washington Post. He hits the nail on the head when it comes to the true motivations of politicians, companies that are jumping on the carbon regulation bandwagon, and even fellow columnists. "Considering this reality, you should treat the pious exhortations to 'do something' with skepticism, disbelief or contempt. These pronouncements are (take your pick) naive, self-interested, misinformed, stupid or dishonest. Politicians mainly want to be seen as reducing global warming. Companies want to polish their images and exploit markets created by new environmental regulations. As for editorialists and pundits, there's no explanation except superficiality or herd behavior."
