Image of the Day: The Tongue of the Malaspina Glacier

Credit: NASA and USGS

A Landsat 7 satellite image shows the tongue of the Malaspina Glacier, the largest glacier in Alaska and the largest piedmont glacier — a glacier that ends on flat land rather than in the ocean — in the world.

Research has shown that glaciers around the world have been retreating at unprecedented rates, and Alaska, which has only 5 percent of the total ice Greenland has, lost a volume of ice equal to nine states 3 feet thick between 2004 and 2007 alone.

Of the approximate 1.25 inches per decade of current sea level rise, researchers estimate that globally, glaciers and ice caps — among which Alaska is making the biggest contribution — are contributing perhaps more than 20 percent of this rate. 


Potential El Niño Winter Impacts With the current El Niño, there is some hope of such an extreme drought easing this winter.
