The Melting of Greenland: The Photos

Here is a short photo post illustrating the melting of Greenland's ice sheets. The speed and scale of the melt moving far more quickly then predicted, with startling changes over the past number of years.

According to scientists, glacial surface meltwater is a factor in ice sheet collapse. As water melts at the surface, it flows downward through the ice through crevaces and moulins where it breaks up ice pacs from the inside and lubricates the surface between glacial undersides and rock.

When you consider the sudden melting of the 700 km3 Larsen B ice shelf in a month, the growth of moulins in Greenland is especially worrisome. I don't think the ice will last a hundred years.
