Thanks Jack I am much better educated now. I too am concerned about this whole thing- to me there is only anecdotal evidence of global warming. If you go deep enough in the Arctic there are tropical jungles there under the ice. That to me would indicate that at one time the world was much warmer than it is now. This phenomenon occured long before human habitation- I'm going to go out on a limb and say that there might not be a relationship between "global warming" and human activity. This is just another way for the rich to get richer.
