United States needs to follow Paris Climate Agreement.  Two degrees already baked in the cake.  That is catastrophic changes for many nations.  Prepare for environmental refugees and displaced persons.  When... now.  Glaciers and artic ice being lost at an unsustainable rate.  Oceans are darker, warmer and more acidic.  Reefs dead, fish scarce and no fix in sight.  This is the top story of the century.  This is not conjecture or fake news.  This is real data and science.  Observatory at Mauna Loa is ground zero for data collection.  Earth is simply to hot. Irreversible feed back loop.  More heat, more sea level rise and more flooding.  That is only considering the co2 load in the atmosphere.  Methane and other greenhouse gases much more destructive.  Got to work on this.
