Sea levels are much higher than we thought. Real-world oceans are making a mockery of flood-risk forecasts based on crude global modeling. And to make matters worse, coastal lands almost everywhere are subsiding faster than anyone realized — often many times faster than the seas are rising.
These findings come from two major new studies that are reshaping our understanding of the threats posed by rising tides and sinking land and underlining the imminent risk of inundation facing tens of millions of people in some of the world’s largest megacities, say researchers not involved in the studies.
“The impacts of sea level rise under climate change have been systematically underestimated,” concluded Matt Palmer, a specialist on sea level rise at the U.K. Met Office’s Hadley Centre for Climate Science. “We could see devastating impacts much earlier than predicted — particularly in the Global South.”
“Taken jointly, these two papers paint a considerably more concerning picture than either would in isolation,” said Franck G... Read more
