It's getting hot in here

Billionare pledges 3 billion to combat global warming

First Warren Buffett says he is donating his wealth to the Bill and Melinda Gates foundation, and now this. Some of the wealthiest people in the world are taking matters into their own hands, trying to help solve the world's problems.

They are not politicians and, as far as I can tell, have no aspirations to run for office. They're doing it because they can, it's the right thing to do and our politicians aren't going to.

Take global warming. Our president is unwilling to even sign the Kyoto Treaty, conservative politicians call it a myth, and the loudest voice on the issue is Al Gore, who holds no office. This is a problem that isn't going away. It's getting worse. And we don't have much time.
