Answer:
28,800,000 cubic meters of water
Step-by-step explanation:
It is calculated that currently there exists 32 million cubic meters of ice on Earth. Most of it is stored in the Antarctic Ice Sheet, a significant portion lies in the Greenlandic Ice Sheet, and a much smaller part in assorted glaciers and ice caps. If all this ice melted, this would release 28,800,000 cubic meters of liquid water into the oceans (32,000,000 x 0.9 = 28,800,000). A study by the Intergovernmental Panel on Climate Change (IPCC) suggest that if this happened, the sea level would rise by a little over 66 meters, pretty much flooding every coastal city on Earth.
