Studies have shown that even the smallest increase in melting of land glaciers can dramatically increase once the process has begun. In the past twenty years, the Pine Island Glacier has been thinning about 5 feet per year, and increasing its rate evermore. One of the reasons this is happening is because the glaciers floating on water that surround the land ice are disappearing by more than 0.6 miles each year. This floating ice served as a sort of protection barrier to the land ice. Therefore, as the floating ice disappears, the land ice rapidly thins. Since the melting of the Pine Glacier accounts for 25% of Antartica's total ice loss, scientists predict it will contribute to a rise in sea level of 0.4 inches in the next few decades.
Along with these disturbing facts about Greenland and the Pine Glacier's contribution to sea levels rising, NASA predicts that the sea level will rise 3 feet by 2100. This projection displaces 145 million people and affects the lives of 2 billion people living in coastal regions around the world. Sea levels rising causes flooding damage and storm surges along the coasts everywhere. Damages are predicted to cost up to $100 billion per year by the end of the century if no adaptation measures are taken.
