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…

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.  Highlights https://www.climate.gov/Arctic-2017Read the report at http://acrtic.noaa.gov/report-card

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…
