He has done some good things for NYC, but some of his policies or views don't sit well with me. The article you linked to talks about his support for his Kyoto Protocol which would be a huge disaster for the US especially considering that the 2 of the biggest polluters in the world(China, India) aren't even included. I support his need to try to clean up the enviroment, but his views on that subject seem a little extreme to me.
