A powerhouse of ice flows rapidly on Greenland’s west coast, heading toward the ocean. Some of Earth’s largest icebergs are produced here, tumbling from the tip of Jakobshavn Glacier. Jakobshavn is one of Earth’s fastest-moving glaciers and one of the Greenland Ice Sheet’s largest glaciers. It produces about 10% of Greenland’s icebergs. “We don’t have a good […]
Scientists have produced the first remote sensing analysis of how water clouded by sediment in glacier meltwater moves on the surface of Kachemak Bay. The bay on Alaska’s Kenai Peninsula is home to a rich variety of marine life that can be affected by the sediment. Work led by Lea Hartl of the Alaska Climate Research […]
Glaciers worldwide are withering. Half of them will disappear by the end of this century, and much of the lost ice will vanish from mountains in Alaska, scientists say. Authors of a recent cover story in the journal Science used high-performance computers to predict the fate of 215,547 glaciers on Earth. They excluded the great […]
As glaciers worldwide retreat due to climate change, managers of national parks need to know what’s on the horizon to prepare for the future. A new study from the University of Washington and the National Park Service measures 38 years of change for glaciers in Kenai Fjords National Park, a stunning jewel about two hours […]
