The monetary impact of changes in snowfall due to climate change is likely in the trillions of dollars. Professor Matthew Sturm, with the University of Alaska Fairbanks Geophysical Institute, reported in a recent paper for the American Geophysical Union that the costs of snowfall changes are “measured in trillions, not billions, of dollars.” Sturm collaborated […]
Glaciers and ice sheets move in unique and sometimes surprising patterns, as evidenced by a new capability that uses satellite images to map the speed of flowing ice in Greenland, Antarctica and mountain ranges around the world. With imagery and data from Landsat 8, a joint mission of NASA and the U.S. Geological Survey, […]
Pine Island Glacier — about the size of Florida and one of the largest ice streams in Antarctica — has been thinning and retreating at an alarming rate since 1992, when satellite images first began to document the change. New evidence suggests that the thinning and retreat of Pine Island Glacier was underway as early […]
Along Alaska’s southern coast, harbor seals use icebergs from tidewater glaciers as platforms to give birth, nurse, molt and avoid predators. As these glaciers melt and thin, some may retreat onto land and no longer calve into the ocean. Researchers from the University of Alaska Fairbanks Geophysical Institute and the National Park Service have successfully […]
