Recent published research shows the danger of massive, potentially irreversible, global sea-level rise within the next couple of centuries should temperatures overshoot 2°C. Perhaps most sobering, this loss may become rapid and permanent, with no halt in ice loss even should CO2 concentrations return t pre-industrial levels; and rates approaching 5 cm/year by 2150, and 10 meters of sea-level rise by 2300 should today’s emissions levels continue. IPCC scientists provide a clear-eyed look at risks from Antarctica, and implications for the Paris Agreement temperature goals. SIDS and future generations.
