Sea level rise

Reportedly that the rate of sea level rise may increase even faster than scientists could expect. Actually there are many causes why that can happen. But one of them is the melting of the West Antarctic Ice Sheet. The ice sheet is accounted as an “unstoppable” yet. In the U.S. alone, nearly 30,000 square miles of land – home to 12.3 million people today – lies less than 10 feet under the high-tide line, including more than half the area of 40 large U.S. cities like New York City, Boston and New Orleans. Roughly one third of the U.S. population lives on low-lying land that is vulnerable to consequences of varying severity, from permanent inundation to saltwater intrusion into freshwater sources. Unless adaptation measures are taken, sea level rise could cost the globe $1 trillion annually by 2050.
