[GWSG] Sensitivity 5C+?; industrial H; Greenland dwindles; SLR accelerates; quick thawing permafrost; CAES w/o the CH4

[Tilley, Al]

1. A Bloomberg article summarizes the alarm and puzzlement about the climate models which have begun to indicate a climate sensitivity in excess of 5C. https://www.bloomberg.com/news/features/2020-02-03/climate-models-are-running-red-hot-and-scientists-don-t-know-why



2. Producing hydrogen as a fuel has been a covert way to support the methane industry, as that has been the source of much H. Now renewable energy and the falling price of electrolyzers is making the electrolysis of water a cheaper source of H for electricity, transport, heat, and fuel. Essentially industrial hydrogen embodies renewable energy in a stable and flexible storage medium. https://climatecrocks.com/2020/02/03/entering-the-age-of-h2/



3. Warm ocean currents are melting some of Greenland’s glaciers from underneath, contributing to a seven-fold increase in melting since 1992. https://www.msn.com/en-us/weather/topstories/climate-change-scientists-find-another-threat-to-greenlands-glaciers-lurking-beneath-the-ice/ar-BBZCpNd?ocid=spartandhp



4. 25 of 32 US tidal stations reported accelerating rates of sea level rise last year, toward the higher end of NOAA projections. Those should be used for resilience planning. The strongest rise was along the East Coast. https://phys.org/news/2020-02-sea-level-cards-trend.html



5. Abrupt thawing of Arctic permafrost can release large amounts of carbon quickly. Current models do not take abrupt thaw into account; the new findings will double the amount of expected carbon emissions from the region. The need for action just became yet more urgent.  https://www.wired.com/story/abrupt-permafrost-thaw/



6. Compressed air energy storage has in the past used methane to heat the air as it decompresses. Total Energy describes its new emissions free technology in a 2.5 minute video. https://climatecrocks.com/2020/02/04/compressed-air-storage-another-sustainable-option/
