UPDATE March 19th 2018. There is a new study published after we released this video, it shines more light onto the subject of thawed soil carbon activation. The Arctic’s carbon bomb might be even more potent than we thought https://www.washingtonpost.com/news/energy-environment/wp/2018/03/19/the-arctics-carbon-bomb-might-be-even-more-potent-than-we-thought Direct study link https://www.nature.com/articles/s41558-018-0095-z.epdf?referrer_access_token=QimruZqY0uQyvJhlxat8ItRgN0jAjWel9jnR3ZoTv0N8I-MYIYWzKL_kSfxnCJqK5MhEqa1ECTKGMkwkdtwwdRBnpqZb1-iie3xj4GeIn_ATzYOYZ_qH4owg6tA5W_yYLypIP2SUN5-B1T5yexwNadXdwCZt3wyAarxCPC0Nv3lXljO2n4dUQQDimyNua3Tnd21O6bRqgq5YEXModik7bKXZTRVCsXL5btzFCn1ue-c-ltsrUkl1ZlWfKJ4h4XiaA6qEcw5474V3V54ossVOcVqoW3t1_ow7xF60nqcgwrNXk5mNIEx9Z6M48j2ZmaN7wOxfwaQ5BDzgkO51tABEDT710d1AeRsMA44IH8haLVAGf3Z3T9_HC0MLnAaJfWJo&tracking_referrer=www.washingtonpost.com Transcript The trend from frozen tundra soils shifting to thermokarst erosion…

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…

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.  Highlights https://www.climate.gov/Arctic-2017Read the report at http://acrtic.noaa.gov/report-card
