"Give another solution? to what? the possibility that our contribution to the natural global weather cycles is enough to get excieted about?"
It is. Again, - was calculated, predicted and is now being measured.
And Elfie:
"The global warming issue isn't something that is unanimously agreed upon by the worlds scientists"
Not quite but almost. This cuts across many parts of science and research, (such as metreology, oceanology, physics, and even agriculture).
Bottom line is that MOST scientists agree upon it. MOST people also agree upon the earth being round, but there are some who still belive it's flat.
