I saw some report on global warming and the effects on economy for us Swedes. The really interesting part was that we as a country would actually GAIN from global warming in the next 100 years..
faster growing crops, trees and wine would be a bonus that would outweigh the cost of raising waterlevels and other things.

there is not doubt in my mind that man created this mess we live in right now though and we need to adress the problems now.
