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

Scientist Reveals 7% More Water Vapor Fuels Storms Today

Jennifer Francis, Ph.D., Research Professor I, Department of Marine and Coastal Sciences, Rutgers University, speaks about extreme weather changes. And how are those related to climate change? In this presentation, Dr. Francis will explain new research that links increasing extreme weather events with the rapidly warming and melting Arctic during recent decades. Evidence suggests that…

Polar Bears hunting Seals

Exciting polar bear cam b-roll USGS footage from the bear’s perspective from 2014, 2015, and 2016. The USGS Alaska Science Center Polar Bear Research Project conducts long-term research on polar bears to inform, local, state, national and international policy makers regarding conservation and management of the species and its habitat. The USGS’s studies are primarily…

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…
