It will take the better part of a century to melt the Greenland ice cap and the Antarctic ice sheets which if both melted would raise sea levels 200 meters. It’s not a linear melt it speeds up as the ice sheet thermal mass shrinks. For the next two decades even if maximum possible melting happened it would be a few centimeters at most well under half a meter it would not be until the half way melting point that the positive feed back loop really kicks in. It has happened at least twice in the past that both Antarctica and Greenland have been ice free and sea levels were 200+ meters higher we currently are nowhere close to the maximum possible sea level throughout geological history.
I believe, if all of the ice where to melt (which it won’t ) the ocean rise would be 60 meters.
