Comment on The rate of sea level rise increased 50% in the last two decades, new study finds

AP Photo/Luigi Costantini, FileA new study published in Nature found that sea level rise shot up between 1993 and 2014 because of climate change. The authors of the study calculated that in those two decades, there was a 50% in the rate at which seas are rising — from about 2.2 millimeters per year in 1993 to about 3.3 millimeters per year in 2014. The biggest increase in contributions to that sea-level rise came from the melting of Greenland's ice sheet.
