This program explains in detail the dangers we are facing from data and factors never before considered. It also shows the global scope of the problem and unimaginable forces at work. And CO2 plays a major role.
It also clearly shows that as the ice melts from the surface it deposits layer and layer of dark pollutants on top of the ice making it ever darker and absorbing more warmth and the water pouring down thousands of feet of ice, lifting it up and lubricating the bottom of the glaciers, increasing their rate of speed. We are looking at an exponentially increasing effect of warming and the conclusion that somewhere between 50 - 100 years the face of the earth may change drastically, driving billions of people further inland.
All by all a “must see” for anyone who is interested in Global warming and it’s effects.
