6 Degree Celsius or Farenheit? - Global Warming

Ever since I came across this video, I've had this question in my mind. It would be extremely far-fetched to say that six degrees Farenheit rise in global temperature is enough to wipe us all out, but 6 degrees Celsius is a different story.



If the theory explained in this video is true, we as citizens of this Earth must take a stand against it. We HAVE to do something to stop it. But then alot of questions start to arise: Can we really stop this from occurring? How long will it take us to revert the damage already caused? Why aren't WE doing something already?
