I recently saw "An Inconvenient Truth", the movie Al Gore produced to spread the message of global warming dangers. It has a lot of nice pictures, like the one of Manhattan sinking. Not a long time ago I also saw professor Lomborg in the TV. He is known to be the economist saying it is wrong to spend money on this global warming issue. I think Lomborg makes a better case than Al Gore, so I'm still skeptical on this topic.
