On the Greenland Ice Sheet — The midnight sun still gleamed at 1 a.m. across the brilliant expanse of the Greenland ice sheet. Brandon Overstreet, a doctoral candidate in hydrology at the University of Wyoming, picked his way across the frozen landscape, clipped his climbing harness to an anchor in the ice and crept toward the edge of a river that rushed downstream toward an enormous sinkhole.
If he fell in, “the death rate is 100 percent,” said Mr. Overstreet’s friend and fellow researcher, Lincoln Pitcher.
But Mr. Overstreet’s task, to collect critical data from the river, is essential to understanding one of the most consequential impacts of global warming. The scientific data he and a team of six other researchers collect here could yield groundbreaking information on the rate at which the melting of the Greenland ice sheet, one of the biggest and fastest-melting chunks of ice on Earth, will drive up sea levels in the coming decades. The full melting of Greenland’s ice sheet could increase sea levels by about 20 feet.

Millions of Americans live in places where it’s too late to slow the threat of rising sea levels, a new study warns, and researchers are hoping those findings will serve as a call to action for cities that can still be saved by cutting carbon emissions.
The study, published Monday in the journal Proceedings of the National Academy of Sciences, examines how much rising sea levels will affect cities across the United States over time if carbon emissions stay the same or decrease. The most startling finding is that 414 towns and cities have already passed their lock-in date, or the point at which it’s guaranteed that more than half the city’s populated land will eventually be underwater no matter how much humans decrease carbon emissions; it’s just a matter of when.
That’s “the date where we let the genie out of the bottle, when it’s past the point of no return,” lead study author Benjamin Strauss of Climate Central told The Huffington Post.
