Climate change is inherently unpredictable.
I will say though I do think human industry is certainly negatively impacting the environment in which we live in.
Even people who love coal and nuclear ... would you build your house and raise your children next door to one of those factories? Would you let your kids swim in the waters in Louisana where dead fish are turning up every day thanks to BP?
Who knows what the hell is in our drinking water or the amount of pesticides we spray onto our fruits and vegetables.
I think things like cancer rates and the dropping of testosterone in the male population will continue on unabated in the next 20-30 years.
More than global warming I'd be worried that all the sh*t we dump into the water and pump into the air and all the deforestation we've done might cause some kind of virus/bug (not unlike bird flu or mad cow but much worse) to rapidly spread through our water/food sources and not get under control until it's caused a catastrophic loss of life.
