The irony of citing the 'global cooling' talking point in this reply is beautiful for 2 reasons. First, see Buckeye I.I.C.'s reply below. It was maybe a very small number of scientists who supported this. It was based on sound evidence at the time, it was just the prediction that it might continue that was incorrect:
"The story observed – accurately – that there had been a gradual decrease in global average temperatures from about 1940, now believed to be a consequence of soot and aerosols that offered a partial shield to the earth as well as the gradual retreat of an abnormally warm interlude." - http://www.scientificamerican.com/article/how-the-global-cooling-story-came-to-be/
And secondly, once it was determined that that theory was incorrect, it was discredited. From this, you should be able to see that if the same was true of what is predicted now, then global climate change would also become a discredited theory. That's how this weird science thing works.
But all of the above aside, I just don't understand what the downside is to getting off fossil fuels. Honestly, I really enjoy having to feign support for a country full of fanatics that beheads people and won't let women drive and was by most accounts as responsible for 911 as any other. And the pollution. I love that shit too. Who cares that it literally kills and makes sick millions around the world. You can literally see China's smog from space: https://www.youtube.com/watch?v=6YOz9Pxnzho
I'm not saying we could snap our hands and be off fossil fuels tomorrow. I'm saying we've had to drag people like you kicking and screaming at every little investment or effort we've ever tried to make in this direction for the last 30 or so years, and had that not been the case, if we had truly put our money, human inginuity, etc to work over that time, we could have already had a solution by now. Instead we just get people complaining that there are a couple scientists, mostly funded by industry, that either deny or are not convinced it's man-made: http://www.theguardian.com/environment/2015/feb/21/climate-change-denier-willie-soon-funded-energy-industry
