#In the next 100 years, CO2 produced by man will cause a lot more warming, from as low as three degrees C to as high as 8 or 10 degrees C.

#Positive feedbacks in the climate, like increased humidity, will act to triple the warming from CO2, leading to these higher forecasts and perhaps even a tipping point into climactic disaster

#The bad effects of warming greatly outweigh the positive effects, and we are already seeing the front end of these bad effects today (polar bears dying, glaciers melting, etc)

#These bad effects, or even a small risk of them, easily justify massive intervention today in reducing economic activity and greenhouse gas production [http://www.climate-skeptic.com/2007/09/chapter-1-summa.html]
