Seems like several folks answered Doug R pretty well while I was out..... but to reply to a couple of points specifically:

"...And you believe .... that the scientists that"will 'find' data that prove anything" could not possibly be..." etc...

Doug....you COULD buy 'some' to say anything, but not all of them! The vast majority of those who could claim expertise agree.....without being bought.
You missed my point... vested interest in this lies with those who do not WISH to believe in warming! THEY are the ones who will fund 'studies' that show what they wish...like the tobacco companies used to do. Remember?.."There is no real proof that smoking 'causes' cancer...harrumph! WE have done many studies that show little correlation!" *big grin* It was sorta funny when they traced who paid who for what!

"The cost of making the changes required is entirely too high."

The cost of NOT doing it could be much higher, though measured in different coin.
