Sea level rise is real, and it’s getting worse.
A study published in the journal Nature Climate Change shows that global sea level rise jumped by 50 percent from 1993 to 2014, the most recent year for which data are available. In 2014, sea levels rose 3.3 millimeters—more than an eighth of an inch—while in 1993 they ticked up 2.2 millimeters.
The paper found that melting of the Greenland ice sheet is the major new contributor. In 1993, it accounted for only 5 percent of the rise, but in 2014 it was responsible for one-quarter of the increase. The paper looked at satellite measurements and tide gauges, which measure sea levels around the world.
