I've never understood the "skepticism" about global warming. I think "myth perpetuated by far right commentators" is a better phrase than "skepticism", as there is absolutely no doubt in the mainstream scientific community that global climate change is occurring.
We know that CO2 in atmosphere causes changes in the earth's climate. We know that one output of burning fossil fuels is CO2. We know that the amount of CO2 in the earth's atmosphere is increasing by a larger percentage than at any time in history. We know that each passing year is the "hottest year on record". We know that more droughts are happening globally each year. We know that we're having unusual superstorms in increasing frequency.
Yet while the rest of the world and the majority of Americans believe climate change is real and present, significant portion of Americans (And it's only Americans. No other advanced nation in the world believes otherwise.) believe this crap perpetuated by Rush Limbaugh, Fox News, and a few dumbass Republicans in Congress that climate change is either a huge liberal hoax, a theory, or that it's just a "natural" process that occurs throughout history.
Personally, I think it's too late to do anything meaningful about it. We've made our bed and now it's time to lie in it. Sometimes I wonder if our ultimate extinction is the real "end of days" prophecy the Bible was talking about. God cannot be happy with how humanity disregarded and polluted the Earth He made for us.
