100 years is all this model presents. The earths climate goes back millions and millions of years, it went through ice ages and incredibly hot periods all on its own. This model only goes back 100 years and yet peopple are claiming that its president bush's fault?
There is no doubt that the globe currently has a warming trend. There is, however, incredible doubt that humans are causing it. Say whatever you want, cite any scientist, it doesnt matter. There is no way to prove humans are causing this warming trend.
Anyways, this little warming period is also coming along with the greatest improvement of worldwide living conditions, life expentancy, and wealth. Everyone is worrying about nothing.
