Sea Level Rise Is On the Up and Up
Sea level rise is a game of millimeters a year, but those millimeters add up to a huge amount of water entering the world’s oceans. And the rising tide could eventually swamp cities around the globe.
With tide gauges distributed sparsely around the planet, scientists have turned to satellites to provide a global picture of sea level since the early 1990s. New research published on Monday in Nature Climate Change refines those satellite estimates and provides some good and bad news. The good news? Total sea level rise is lower than previous estimates. The bad news? Sea level rise rates are speeding up.
