I am very sceptical as well, all it takes is a quick deduction of the scales involved here and to me, mans effects cannot be considered significant enough that we can somehow control the climate of our planet through manipulation of our own personal emissions. To me that seems ridiculous anyway.
As for the arguments, i am with the 'see what happens and adapt (as we have done for many many years!) to suit' train of thought. But you will always have the 'what iff's' of the global warming fanatics so they'll never stop arguing.
Maybee the money being piled into this reseach would be better spend saving the lives of those currently inhabiting the planet, ie aids, cancer cures etc. Its quite some debate! Interesting nontheless.
