Global Warming is a political issue. Its perpetuated by environmentalists who want to blame the United States for everything that is wrong in the world. More and more, scientists are coming to the conclusion that its the activity in the sun, and not man that is causing the recent warming. Its a cycle in the sun, and there is data to back that up. Its repeated itself just in the last 400 years or less. But environmentalist whackos don't want to hear that. They're too bent on destroying industry and throwing us all back into the horse and carriage age. Of course, then, they will complain about the horse patties in the streets.
