Having to change or alter our lives drastically or negatively to combat global warming is a myth. The only things stopping the world from taking on this challenge is Ignorance.
As for you saying we should get used to living in warmer termperatures clearly displays your ignorance to the situation. How about this, why don't you go tell the trees and all other palnt life, the corals of the seas and the crops in the fields to just get used to warmer temperatures. And tell them now, cause they don't last forever when the temps change and change quickly.
As for your theory on cooling... global warming models suggest parts of the world will cool considerably and to the point where those areas wont be inhabitable.
And yes, I know we are talking about man made global warming.
Nutjobs like you should take a little time away from church and toon into the science and discovery channels now and then. We all secretly know that the earth is only 6500 years old but if you can get past that long enough to watch presentations other than from the pulpit, you might even come to the conclusion that the world is bigger than your neighborhood and that your Ignorance has cost you a lot of knowledge that has always been at your finger tips.
