When glaciers and ice shelves melt, sea levels rise. In fact, scientists suggest that sea levels rose almost 7 inches (17.8 cm) in the 20th century. So if glaciers continue to melt and the rise in sea level is only 1 or 2 inches (2.54 5 cm), this could potentially flood low-lying coasts. But if parts of the West Antarctic Ice Sheet melted, it could raise sea levels more than 32 feet (9.7 meters) and wipe out entire coastal areas.
Research predictions indicate a rising sea level.
