Back in 2011, a Cornell University research team first made the groundbreaking discovery that leaking methane from the shale gas fracking boom could make burning fracked gas worse for the climate than coal. https://www.desmogblog.com/2018/04/11/climate-change-two-degree-warming-fracking-natural-gas-rush-ingraffea Why a half-degree temperature rise is a big deal https://climate.nasa.gov/news/2458/why-a-half-degree-temperature-rise-is-a-big-deal Paris 1.5-2°C target far from safe, say world-leading scientists http://www.climatecodered.org/2017/07/paris-15-2c-target-far-from-safe-say.html Transcript…
Scientist speculated that pingos may erupt and lead to the creation of craters – small lakes, thaw ponds. New satellite observations reveal continuous trend.

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 Permafrost…

The highest estimates for Bitcoins annual terawatt hours consumption is 28.67. This means, more than 3 times more efficient than a very conservative calculation of the cost of the global banking system.

Stefan Rahmstorf speaks at the 2017 Bonn climate conference, explaining the basics of global climate change, and outlines our current emissions pathway – asking if we can control the climate crisis. The talk is titled Climate Action and Human Wellbeing at a Crossroads: Historical Transformation or Backlash?

This NASA visualization is based on the latest IPCC report, and uses the business as usual scenario, where carbon dioxide concentrations rise to 936 parts per million—more than double today’s levels of 400 parts per million—by the year 2100. Temperature anomalies are estimated to be close to 4°C in the Arctic. https://svs.gsfc.nasa.gov/cgi-bin/details.cgi?aid=11453
The evidence is overwhelming that natural gas has no net climate benefit on timescales that matters to humans. A new study found that just the methane emissions leaking from New Mexico’s gas and oil industry are equivalent to the climate impact of approximately 12 coal-fired power plants. https://thinkprogress.org/natural-gas-no-climate-benefit-b9118a087875 Natural Gas has Major Role in Climate…
