George Will explains for The Daily Caller why global warming alarmists approach the subject with such zeal.

“Global warming is socialism by the back door,” Will argued in this segment of the interview when asked to respond to his global warming critics. “I mean, the whole point of global warming is it is a rationalization for progressives to do what progressives want to do, which is concentrate more and more power in Washington, more and more Washington power in the executive branch, more and more executive branch power in independent czars and agencies, to micromanage the lives of the American people.”
