NASA Satellites Detect Pothole on Road to Higher Seas
Like mercury in a thermometer, ocean waters expand as they warm which contributes to drive sea levels higher over the long term. For the past 18 years, the U.S./French Jason-1, Jason-2 and Topex/Poseidon spacecraft have been monitoring the gradual rise of the world’s ocean in response to global warming.This year, continents got extra dose of rain, so much so that global sea levels actually fell over most of the last year.
