Controlling greenhouse gas emissions in the coming decades could substantially reduce the consequences of carbon releases from thawing permafrost during the next 300 years, according to a new paper published this week in the Proceedings of National Academy of Sciences. Conversely, climate policy that results in little or no effort to control greenhouse gases like carbon […]
A major shift in western Arctic wind patterns occurred throughout the winter of 2017 and the resulting changes in sea ice movement are possible indicators of a changing climate, says Kent Moore, a professor of physics at the University of Toronto Mississauga. Thanks to data collected by buoys dropped from aircraft onto the Arctic Ocean’s […]
Scientists from Rutgers University-New Brunswick and Atmospheric and Environmental Research (AER) have linked the frequency of extreme winter weather in the United States to Arctic temperatures. Their research was published today in Nature Communications. “Basically, this confirms the story I’ve been telling for a couple of years now,” said study co-author Jennifer Francis, research professor of marine and coastal […]
Researchers have discovered that thawing permafrost in the Northern Hemisphere stores twice as much mercury as the rest of the planet’s soils, atmosphere, and oceans. The finding has significant implications for human health and ecosystems worldwide. In a new study, scientists measured mercury concentrations in cores of frozen ground—or permafrost—from Alaska and used the data to […]
