Air Temperatures in the Arctic are Driving System Change

By Sue Mitchell | Geophysical Institute on Apr 13, 2019   Featured, The Arctic and Alaska Science  

Air Temperatures in the Arctic are Driving System Change

 A new paper shows that air temperature is the “smoking gun” behind climate change in the Arctic, according to John Walsh, chief scientist for the University of Alaska Fairbanks International Arctic Research Center. Several UAF researchers are co-authors on the paper, which says that “increasing air temperatures and precipitation are drivers of major changes […]

Unmanned Aircraft will Test Medical Supply Deliveries

By Sue Mitchell | Geophysical Institute on Jan 25, 2019   Featured, Health, Interior Alaska  

Unmanned Aircraft will Test Medical Supply Deliveries

Unmanned aircraft will soon be deployed to test the feasibility of delivering emergency medical supplies across Alaska as part of a national initiative from the U.S. Department of Transportation and the White House. The Federal Aviation Administration and DOT expanded the scope of the Alaska Unmanned Aircraft Systems Integration Pilot Program’s efforts to include medical […]

Study: Degrading Permafrost puts Arctic Infrastructure at Risk by Mid-Century

Study: Degrading Permafrost puts Arctic Infrastructure at Risk by Mid-Century

[dropcap]S[/dropcap]eventy percent of the current infrastructure in the Arctic has a high potential to be affected by thawing permafrost in the next 30 years. Even meeting the climate change targets of the Paris Agreement will not substantially reduce those projected impacts, according to a new study published in Nature Communications. “Much more needs to be […]

Researchers Take on Atmospheric Effects of Arctic Snowmelt

Researchers Take on Atmospheric Effects of Arctic Snowmelt

Researchers at the University of Alaska Fairbanks’ Geophysical Institute are exploring the changing chemistry of the Arctic’s atmosphere to help answer the question of what happens as snow and ice begin to melt. The research, led by chemistry professor William R. Simpson, is concerned with the Arctic’s reactive bromine season, which is the period of […]

Value of Snow is in the Trillions of Dollars

By Sue Mitchell | Geophysical Institute on May 3, 2017   Featured, The Arctic and Alaska Science  

Value of Snow is in the Trillions of Dollars

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 […]

Satellite Provides Global View of the Speed of Ice

By Sue Mitchell | Geophysical Institute on Dec 13, 2016   Featured, Science/Education, The Arctic and Alaska Science  

Satellite Provides Global View of the Speed of Ice

  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, […]

West Antarctica’s Largest Glacier Started Retreating in 1940s

By Sue Mitchell | Geophysical Institute on Dec 7, 2016   Featured, Science/Education  

West Antarctica’s Largest Glacier Started Retreating in 1940s

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 […]

Project Tests Method for Monitoring Ice Conditions

Project Tests Method for Monitoring Ice Conditions

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 […]
