These people who believe all this global warming BS don't have any backbone. If they did, and if they really believed it, they'd give up their cars, electric power, airline travel, processed food, and move back into caves. What are they waiting for?
They drive a Toyota Prius to assuage their guilt. Meanwhile, they keep their 3000 sq ft house and turn the a/c down to 68 degrees, and they commute alone and they recycle all their garbage, which consumes more energy and resources than putting it in the dump. By hey, it makes them feel good and that's what it's all about.
