By Andrew Angle 13 September 2018 (GlacierHub) – Few areas of the planet have been more affected by climate change than the mountain cryosphere, where negative impacts like glacier recession far exceed any positives like short-term increases in glacial runoff. These adverse changes make highland environments ideal for examining the policy concept of Loss and […]
By Mari N. Jensen 30 August 2018 (UA News) – As the last ice age came to an end and the planet warmed, the Earth’s vegetation changed dramatically, reports a University of Arizona-led international research team in the journal Science.The current warming from climate change may drive an equally dramatic change in vegetation within the […]
By Ned Rozell 21 June 2018 FAIRBANKS (Daily News-Miner) – Just outside my window here at the University of Alaska Fairbanks, workers are drilling into the asphalt of a parking lot using a truck-mounted rig. They twist a hollow bit 25 feet into the ground and pull up hard, clear evidence of why the blacktop […]
6 August 2018 (Stockholm Resilience Centre) – An international team of scientists has published a study in Proceedings of the National Academy of Sciences (PNAS) showing that even if the carbon emission reductions called for in the Paris Agreement are met, there is a risk of Earth entering what the scientists call “Hothouse Earth” conditions.A […]
WASHINGTON D.C., 5 February 2018 (AGU) – Researchers have discovered permafrost in the northern hemisphere stores massive amounts of natural mercury, a finding with significant implications for human health and ecosystems worldwide.In a new study, scientists measured mercury concentrations in permafrost cores from Alaska and estimated how much mercury has been trapped in permafrost north […]
By Beth Brown 5 September 2017 NUNAVUT (Nunatsiaq News) – The world’s average global temperature is only one degree Celsius away from a potential climate catastrophe to which few regions would be more vulnerable than the Arctic. That’s according to well-known author, historian and journalist Gwynne Dyer, who is a frequent commentator on international affairs, […]
By Henry Fountain 23 August 2017 YUKON DELTA NATIONAL WILDLIFE REFUGE, Alaska (The New York Times) – The Arctic is warming about twice as fast as other parts of the planet, and even here in sub-Arctic Alaska the rate of warming is high. Sea ice and wildlife habitat are disappearing; higher sea levels threaten coastal […]
By Mark Floyd 23 August 2017CORVALLIS, Oregon (OSU) – Scientists concerned that global warming may release huge stores of methane from reservoirs beneath Arctic tundra and deposits of marine hydrates – a theory known as the “clathrate gun” hypothesis – have turned to geologic history to search for evidence of significant methane release during past […]
By JoAnna Wendel 11 August 2017 (Eos) – In a real clash of fire and ice, a massive wildfire in southern Greenland has captured the world’s attention.At the end of July, a couple of NASA satellites detected hot spots in Greenland that indicated fire, said Mark Ruminski, a team leader for a hazard mapping system […]
3 August 2017 (CIRES) – On the North Slope of Alaska, snow is melting earlier in the spring and the snow-in date is happening later in the fall, according to a new study by CIRES and NOAA researchers. Atmospheric dynamics and sea ice conditions are behind this lengthening of the snow-free season, the scientists found, […]
