TEDxTheEvergreenStateCollege – David Roberts – Climate Change is Simple
This is a must see video. If you are skeptical about what he is saying, then dig into the data and prove him wrong. I hope you will leave a comment on this page with your findings. The point is that we, as a society, can’t ignore the potential implications for our children and their children. Please share this with everyone you know.
PRAGWATER 
I know that the title of this post is extreme and I apologize for that. We really do not know in what way the environment will compensate for the positive feedbacks that David Roberts talked about. Nevertheless, the fact that what he described is a possibility really shook me. After watching the Ted Talk, for the first time perhaps, I contemplated the end of the world as we know it. I guess I am one of those people who thought that we will adapt. We will move populations around, make some irritating sacrifices, and then move on. But Roberts explains that if the positive feedbacks pass beyond a certain point, they will go out of control and we could theoretically see 12 degree C average temperature increases by 2130. This means that half the earth could be seeing high temperatures of 175 degrees F, which is lethal. He also talks about the extinction of half of all the species on the planet. It is hard to image the trouble that humans would be in if this happens. I have to admit that I have not read the research papers that made these estimates, but I will make it a personal goal to track them down and read them.
Apparently there is still time for us to influence the rate of increase in global temperatures, and even reverse the direction. This will, however, require the leaders of the world to take unified action, which sadly seems unlikely. Maybe we need an Occupy movement for the Climate.
Oops!!! I made huge typo in the above comment. In referring to the out of control temperature rise of 12 degrees C, I mistakenly typed 2030 when it should have been 2130. Sorry about that for anyone who read the comment before I fixed it.
