Ice sheets over Antarctica and Greenland are shrinking at an incredible rate of 120 cubic miles per year, and accelerating (the rate of ice loss has more than doubled since 2009). While part of Antarctica is actually increasing in ice cover, overall the continent is on a definite decline. Most of the ice loss, 90 cubic miles per year, is as a result of melting in Greenland. The data comes from the CryoSat-2 satellite measuring the altitude of the ice over the continents. Scientists have been using satellites to measure ice levels for about twenty years now.

It’s sad to see our society at such an advanced level technologically, yet turning a blind eye to this problem. Man-made climate change is a fact and one that will have to be dealt with sooner or later. It’ll be expensive, but the costs only go up over time.
