Glacier in Alaska

In the middle of this false-colour image, you can see the tongue of the Malaspina glacier. The glacier makes its way from the mountains in the north and is separated from the sea by its terminal moraine as can be seen in the lower part of the picture. Without the moraine or in the case of a sea-level rise, the glacier would come in contact with the warmer sea water and it would retreat more quickly than it does now. Satellite images and measurements on the ground show that most glaciers in Alaska are getting thinner and that only a few dozen are gaining in ice mass.
