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 civilization 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…

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…

NASA’s Mission to Explore Greenland’s Ice Melt (Raw)

The Oceans Melting Greenland mission seeks to understand how ocean water is contributing to ice loss in Greenland. In October 2017, mission scientists and crew dropped 240 ocean probes from a C-130 aircraft into the waters around Greenland to measure ocean temperature. Footage includes interior and exterior shots of the aircraft with crew and scientists…

Arctic Sea Ice Extent 2nd lowest on Record for the Date

Another “warm” and slow freeze season in the #Arctic. Sea ice extent is the 2nd lowest on record for the date (2016 – lowest) & 1.9 million km^2 below the 1980s average… https://twitter.com/ZLabe/status/932663163476045825 Arctic Sea Ice Extent/Concentration http://sites.uci.edu/zlabe/arctic-sea-ice-extentconcentration Sound effects by http://TrailerMusicAcademy.com

What’s Happening to the Greenland Ice Sheet? (October 2017)

The Greenland ice sheet is one of the largest contributors to global sea level rise, and if completely melted, could add ~7 meters to sea level. In recent years, the imbalance of the ice sheet has increased with warmer atmospheric conditions. In this talk, Visiting Assistant Professor Samiah Moustafa describes the field’s current knowledge on…
