Sea levels over the past two decades have risen faster than previously thought, suggests a new study that reassesses the accuracy of satellite data.
The study by an international team of scientists, published Monday in Nature Climate Change , compares satellite records of sea levels made from 1993 to mid-2014 to tide gauge records.
Lead author and geophysicist Christopher Watson says the study results address an ongoing puzzle about sea level rise.
Previous studies based on tide gauge or satellite data alone have suggested a slowing in the rate of sea level rise over the past decade relative to the one before it.
“That was a puzzle because it coincides with […]
