It was in the news last week, that they changed back to global warming. Even the weather channel was talking about it. But whatever. Will this century be a hot on? Good chance. Has polar ice decreased in the last 3 decade? Yes . Did we cause it? To a certain degree. Can we stop it? Maybe superman, but not us even as a whole.
Theres a hawaiian word i used to love. "Pono" it means do what is right. Its all you gotta do. Take care of the earth best you can, dont worry about priuses, just make the most out of your trips if you get crappy mileage.
And last but not least STAY ON TOPIC!!
The Last Great American Hero... the demi-god... to which speed means freedom of the soul.
