What idiots. Why make a big deal out of global warming. Through out earth history, the earth warms up and it then cools down. It goes through cycles. Plus the atmosphere changes its chemical content also. High CO2, then high O2, then high. . . . etc.
People should worry about many other things: asteriods; sun spots; moon falling out of orbit; disease; war; over population; starvation; heaven; God-no God; hell-devil-no devil; etc etc and etc.
