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

Did a Greenland Asteroid Cause Abrupt Warming Last Ice Age?

We report the discovery of a large impact crater beneath Hiawatha Glacier in northwest Greenland. From airborne radar surveys, we identify a 31-kilometer-wide, circular bedrock depression beneath up to a kilometer of ice http://advances.sciencemag.org/content/4/11/eaar8173 Hiawatha Glacier https://en.wikipedia.org/wiki/Hiawatha_Glacier Sources Discovering a massive meteorite crater https://www.youtube.com/watch?v=hQ9maLsIcts Massive crater under Greenland’s ice points to climate-altering impact in the…

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…

The 5 Big Climate Unknowns

Climate unknowns include the rate of sea level rise, ozone loss, how the Gulf Stream will react and what it possibly means, the Earth’s response, and the potential for extra methane release from methane clathrates, stored at continental margins. There are many more climate unknowns, for example elaborated in this article https://thinkprogress.org/what-are-the-unknown-unknowns-of-global-warming-1438d934bdee Climate Change Interview…

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.…
