Did you know that the Earth is acutally going to be cooling down over the next 10 years, and that polar bear numbers have increased since 1970's! Annual snow fall has increased in Antartica, and there is not one study that proves that human increased CO2 in the atmostphere has or will warm the planet even one degree. Wanna know the warmest years of the last century? Ask NASA, there scientist concluded that it was the 1930's and not the 1990's. Don't believe the hype of the alarmist.
