The Melting Cryosphere

The Melting Cryosphere

Here’s a look at how the Arctic has been melting.  (Click on the image to go to NASA for a full explanation of what you’re seeing here.)

What we’re seeing all over the world is an accelerating rate of the thawing of permafrost, and the melting of sea ice and glaciers.  I’ve written about this in the context of the Himalayas several times including here.  To go deeper, as it were, on this global phenomenon and how it is being driven by warming and, to an alarming extent, black carbon, visit Ice Core Perspectives from the Climate Change Institute of the University of Maine.  In the meantime, watch this video from Reuters.
