Human-caused climate change, driven mostly by the burning of fossil fuels, has accelerated global sea level rise to the fastest rate in more than 3,000 years. The report by NOAA and other federal agencies — updating a study from 2017 — predicts that ocean levels along U.S. coasts will increase as much by 2050 as they did over the past century.
This amount of water battering the coasts “will create a profound increase in the frequency of coastal flooding, even in the absence of storms or heavy rainfall,” NOAA said.
“We’re unfortunately headed for a flood regime shift,” said William Sweet, an oceanographer at the NOAA National Ocean Service and the nation’s top scientist on sea level…
