If the greenland icecap, the antarctic east and west ice sheets completely melt you will get 200 feet of sea level rise but there is no remote chance of that happening for tens of thousands of years. Over the last 100 years sea-level has risen 6 inches and even the “IPCC” projects a rise of only 7-23 inches over the next 100 years. Current empirical measurements are trending on the low end of 7 inches. So in effect sea level rise will be what we have already experienced and gasp survived.
