Extreme Ice, from Jay Pasch

February 24, 2010 |

 Extreme Ice documents the melting of arctic glaciers.

If one is able to put aside the usual political rhetoric, there is some pretty cutting-edge science going on here. What is of interest is our new understanding of glacial melting observed with never-before-seen time-lapsed photography. More interesting is how the Greenland ice sheet is being affected by the pooling of surface water with great lakes that give way to near-instant draining in a matter of hours, the result of which greases the underbelly of the sheet resulting in oceanic thermal currents, further warming the water-edge of the sheet in feedback fashion.
