The facts of life, re: global climate change.
1) it exists.
2) it may or may not be the result of mankind pumping vast ammounts of CO2 into the atmosphere, 24/7/365. (All evidence points to this being true. differences in solar output, although measurable, are not significant.)
3) It's already too late to stop the worst effects. Even if we all stopped producing greenhouse gasses today, it will take over 100 years for the effects to dissipate.
4) Global Warming will cause extreme weather as more and more energy is pumped into the system, thanks to the trapped warmth. There will be droughts, famines and war because of this. Human fertility rates will plummet. (Add to this the coming shortage of fresh drinking water, and we'll truly have a catastrophe on our hands.)
