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

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…
