Researchers studying a rapid global warming event, around 56 million years ago, have shown evidence of major changes in the intensity of rainfall and flood events. The findings indicate some of the likely implications should current trends of rising carbon dioxide and global warming continue. https://scienmag.com/new-research-indicates-likely-hydrological-implications-of-rapid-global-warming

Another “warm” and slow freeze season in the #Arctic. Sea ice extent is the 2nd lowest on record for the date (2016 – lowest) & 1.9 million km^2 below the 1980s average… https://twitter.com/ZLabe/status/932663163476045825 Arctic Sea Ice Extent/Concentration http://sites.uci.edu/zlabe/arctic-sea-ice-extentconcentration Sound effects by http://TrailerMusicAcademy.com

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
