The truth is that we live next to a variable star and periodically we get warmer and colder. Sometimes we get more plants growing and more co-2 and some time less. Also, we get more volcano activity off and on and spew more chemicals in the air that effects our climate. If we were serious about it we would go nuclear for electricity and mass produce hydrogen for our cars. Good luck. Best thing to do is laugh and ignore these left-wing nut jobs and consume every thing in sight before we die. Heh Heh.
Far as I'm concerned a lot of this stuff is all worshiping Gaia. There is an awful lot more religion in this than meets the eye.
