NASA’s 2018 Permafrost Special “All Hell Breaks Lose”

This week, #NASAExplorers head back in time…by going underground. In the Arctic, a frozen layer of soil – permafrost – trapped dead plants and animals for thousands of years. As the climate warms, that soil is beginning to thaw, releasing carbon dioxide and methane. Release via https://www.youtube.com/watch?v=y7ZbghndiwQ

Permafrost Melt Fires may Accelerate Greenland Melt

Dr. Nikolaos Evangeliou on climate change and wildfires (Oslo, August 2018). Evangeliou works at NILU – Norwegian Institute for Air Research http://nilu.no “If larger fires would burn, they would actually have a substantial impact on melting,” Stohl said. And, there’s a greater chance of such fires, if more of Greenland’s permafrost melts and exposes peat…

Thousands of little Volcano like Hills form in Arctic!

Scientist speculated that pingos may erupt and lead to the creation of craters – small lakes, thaw ponds. New satellite observations reveal continuous trend. The Siberian Times article, Pingo in Arctic goo.gl/mwNnEF / http://siberiantimes.com/other/others/news/crater-formed-by-exploding-pingo-in-arctic-erupts-a-second-time-from-methane-emissions/ The trend from frozen tundra soils shifting to thermokarst erosion and thaw ponds, may in the future be exacerbated by increased…

Waking the Climate Giant

Bill McGuire (University College London) speaks about responses from the Earth crust in this 2016 lecture. He wrote a book on the subject, available at https://www.geolsoc.org.uk/Publications/Bookshop/Search?k=waking&sortexpr=Publication%20Date%20Desc An astonishing transformation over the last 20,000 years has seen our planet flip from a frigid wasteland into the temperate world upon which our civilisation has grown and thrived.…

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 Permafrost…

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…
