Sea Level Rise Speeds Up

Total sea level rise is lower than previous estimates but the rates are accelerating. Currently more than 1 billion people live along shorelines around the world and $11 trillion in assets sit below the 100-year flood mark on coasts. 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.
