Latest Permafrost Stories
University of Alaska Fairbanks researcher Vladimir Romanovsky is one of four scientists who authored a report released today by the United Nations Environmental Programme.
As global warming extends its balmy fingers further into the Arctic regions, defrosting permafrost could release up to 44 billion tons of nitrogen and 850 tons of carbon into the atmosphere, according to a new study from the U.S. Geological Survey.
Watershed covers roughly 20 percent of Canada, including oil sands; The Mackenzie may discharge more water into the Arctic than the St. Lawrence into the Atlantic
A recent study of the Antarctic Ice Sheet suggests that it could be a largely overlooked source of the potent greenhouse gas methane.
The ancient reserves of methane gas seeping from the melting Arctic ice cap told Jeff Chanton and fellow researchers what they already knew: As the permafrost thaws, there is a release of methane, a powerful greenhouse gas that causes climate warming.
The edges of glaciers and Arctic permafrost are where most of the evidence of global warming can be seen, but scientists have recently been traveling to these remote locations for a different reason.
Permafrost zones extend over 50% of Canada's land area.
Scientists describe humanity's global impact as 'The Great Acceleration' and offer ominous outlook: An uncertain future on a much hotter world.
Satellite are seeing changes in land surfaces in high detail at northern latitudes, indicating thawing permafrost. This releases greenhouse gases into parts of the Arctic, exacerbating the effects of climate change.
NSF partners with international team to gather new information on hidden environments and past climate conditions in Antarctica.
