Mountains of empirical data gathered by professional, published climate scientists tells us that the world is getting warmer rapidly when it had been cooling off for the last 5,000 years. It tells us that the cause of that warming is the greenhouse effect acting on the CO2 and other greenhouse gases that humans have put into the atmosphere since the Industrial Revolution. That increased temperature has caused sea level to rise both from thermal expansion and melting land-borne ice The warming is going to fuck with us six ways from Sunday but there are still a small collection of idiots (roughly 10% of the US population) who reject all that science and think its some sort of hoax by people trying to get rich or to destroy our country or the world cause, you know, that motivates a lot of people these days. In fact, from the PoV of these particular individuals, an unquenchable desire to destroy everything is an identifying characteristic of democrats.
So, based on the conclusions of more than 10,000 PhD, published, actively researching climate scientists, I'm convinced that the conclusions of the IPCC are the best idea we have right now as to what's going to happen. Some of you disagree. Bring your evidence cause I'm gonna bring mine.
