I am finding this thread hugely interesting, please keep up the arguments all you pros and antis! My view always was that there are many factors influencing climate, but man is definitely exerting an influence too. I am yet to be convinced how big that influence has been/will be. I don't expect either the strong pros or the antis to be swayed much - everyone wants hard evidence, and future climate change can't be proved. Let's face it, nobody can prove the sun will rise tomorrow. But the opposing views sure make fascinating reading.
