Study suggests current changes in the ocean around Antarctica could trigger steep rise in sea levels

A new study suggests that current conditions in the ocean around Antarctica​ could led to the rapid melting of Antarctic ice and an abrupt 3-4 meter rise in global sea level. Warming in parts of Antarctica is causing land-based ice to melt, adding massive amounts of
