Did you hear the news? Al Gore won the Nobel Peace Prize for his work on climate change. Have you seen The Inconvenient Truth? If not, it is a great start to learn about climate change. It was a really good movie, and it is a great introduction to this. When Gore first talking about climate change in the 70's, they all thought he should be put in a drug treatment center. Low and behold though, he was right. The award him the prize due to his continued work of this.
If you win a Nobel Peace Prize, I guess climate warming is really a problem even if the government won't acknowledge it.
