Retreating glaciers a sign of Alaska’s major meltdown
As the climate warms, glacier retreat is just one impact that
climate scientists expect to happen more frequently. Melting permafrost and sea ice are also causing major problems. Some Alaskan coastal communities have already been forced to move inland as sea level rise erodes the coastline and thawing permafrost causes infrastructure to fail.
Melting this summer is far-outpacing climate projections, says Julienne Stroeve, a research scientist for the National Snow and Ice Data Center (NSIDC), based in Boulder, Colorado.
Alaskan glaciers in total lose ice at a rate of around 75 billion metric tons each year, according to a
2015 study by the U.S. Geological Survey and University of Alaska, Fairbanks. But this summer, reports NSIDC,
glaciers are melting 70 percent faster than the typical rate, thanks to warming temperatures.

Over the past 60 years, the state’s average temperature has increased by about 3 degrees, about twice the rate of warming experienced by the rest of the country,
according to the Environmental Protection Agency, and over the past three months temperatures have run as much as 8 degrees Fahrenheit above normal. Under
current climate projections, temperatures can be expected to rise up to 12 degrees in the north, 10 degrees in the interior, and 8 degrees in the rest of the state by 2050.
A single snowfall of maybe an inch more than has been recorded on that day of the year before is far less significant than what it happening with the glaciers.
