Another great read that puts some perspective into the panic over climate change is this book.
Personally I don't think man made warming is occurring I think that the recorded temperature increases are an artifact of poor measurement sites and 'adjustments' made to the recorded temperatures as well as the Urban Heat Island Effect. Take those things away and there is no increase that can be separated from 'noise' and natural variation. But that's just what I think. If new evidence arises I may change my mind if that evidence is conclusive.
