On air: Bjorn Lomborg is joining us...

... for the whole of Tuesday's programme. For most of you he'll need no introduction, just in case though, this is the self-styled 'skeptical environmentalist' who has refused to accept the majority view of what's happening to our environment and why.

This is his website, here he is on Facebook, this is how Wikipedia describes him, and this is an article where he argues that 'We are frightening children with exaggerations - they believe they don't have a future and that the world is going to end'.
