Permafrost may release largest Mercury source on Earth

There are 32 million gallons worth of mercury, or the equivalent of 50 Olympic swimming pools, trapped in the permafrost. For context, that’s “twice as much mercury as the rest of all soils, the atmosphere, and oceans combined. And it could be released. https://www.washingtonpost.com/news/energy-environment/wp/2018/02/05/the-arctic-is-full-of-toxic-mercury-and-climate-change-is-going-to-release-it   Ambarchik: Research on permafrost at the Siberian arctic coast https://www.youtube.com/watch?v=ZhGcJnRgzy4…

Arctic Sea Ice and Permafrost Status Report 2017

The Arctic is warming faster than anywhere else on Earth, affecting people in the region, fish and wildlife they depend on for food, and their environment. This unprecedented change has ramifications far beyond the region for the global economy, weather, climate, sea level, trade and security. Watch the full Arctic Report 2017 AGU press conference…

Methane in the East Siberian Arctic Shelf (2017)

The East Siberian Arctic Shelf has received more attention in recent years in regards to a potential contribution of the greenhouse gas methane, for the global methane budget, from several different sources. However, more studies are required to better constrain this potential accelerator of ongoing climate change. CREDITS The East Siberian Arctic Shelf has received…

Climate Change in the Arctic and Model Projections

This video with scope on permafrost melting, highlights some of the new developments of our understandings, of what happens in the Arctic due to global warming. The Woods Hole Research Center (WHRC), at the University of Alaska Fairbanks May 11, 2017. Professor of Geophysics Vladimir Romanovsky discusses the impact of Arctic permafrost thaw.
