Human-driven climate change has set in motion massive ice losses in Greenland that couldn’t be halted even if the world stopped emitting greenhouse gases today, according to a new study published Monday. The findings in Nature Climate Change project that it is now inevitable that 3.3 percent of the Greenland ice sheet will melt – equal to 110 trillion tons of ice, the researchers said. That will trigger nearly a foot of global sea-level rise. If the sea level along the U.S. coasts rose by an average of 10 to 12 inches by 2050, the most destructive floods would take place 5 times as often, and moderate floods would become 10 times as frequent.
