way to go doug! first of all, if you're asking him for proof, how about you give us some real proof that global warming is happening..and i don't mean wikipedia. anyone can add anything to wikipedia so obviously it's a refutable source..NOT! and you know your nice lib al gore who's in charge of the energy in the U.S...yeah that lib..go talk to him and tell him to stop burning coal so we don't have "global warming". so yeah why don't all you libs get together and figure out you guys are the ones causing global warming because your own al gore is burning a mighty big hole in that ozone. watch out!
