This Photo Friday, take a look at NASA’s Global Ice Viewer, an online interactive that shows how climate change is impacting glaciers, sea ice and continental ice sheets worldwide. Earlier this month, GlacierHub has also reported that climate change is behind more frequent and powerful avalanches in Alaska. Roughly 10 percent of the world’s surface is covered in ice, but as temperatures rise, the ice is quickly disappearing. Join us in viewing some of Alaska’s great glaciers, before and after several years of intense global warming.

The photos displayed below were curated by NASA, but the original collection belongs to the Glacier Photograph Collection, a searchable database of digital photographs operated by the National Snow and Ice Data Center.
The Alaska Range is a narrow, 700-kilometer mountain range defined by rugged peaks and large U-shaped glacial valleys. The range lies in the southeast corridor of Alaska and is home to Denali, the tallest peak in North America. The Alaska range is part of the American Cordillera and possesses peaks only trumped by those in the Himalayas and Andes.
For many decades, the Alaska Range has played host to an incredible variety of landscapes and ecology, with visitors traveling from all over the world to hike, climb and sight see in Denali National Park. One-sixth of Denali National Park, or approximately one million acres, is covered by glaciers, which transport thousands of tons of ice each year, according to the National Park Service. Take a look at GlacierHub’s collection of images of Alaska’s impressive peaks and low valleys shaped by glacial activity over the past million years.
