just for posterity's sake; a documentary on CNA's forecasting global warming to raise earth temperatures by 5 degrees celsius in 25 years' time. apparently apart from the greenhouse effect, which serves to raise temperatures, there's an opposing effect (which, i conveniently missed out on the name and details..) that serves to actually cool down the earth; this cooling effect is (allegedly) often neglected by climatologists, and serves to show that the 0.6 degree increment in the past century downplays the actual impact of greenhouse gases. and so the usual doomsday-on-the-horizon yada yada. guess we'll know for sure in 20 years' time.

edit: the apparent "cooling effect" is actually global dimming.
