More than three times more people are at risk from rising sea levels than previously believed, research suggests. Land that is currently home to 300 million people will flood at least once a year by 2050 unless carbon emissions are cut significantly and coastal defences strengthened, says the study, published in Nature Communications. This is far above the previous estimate of 80 million. The upward revision is based on a more sophisticated assessment of the topography of coastlines around the world. Previous models used satellite data that overestimated the altitude of land due to tall buildings and trees. The new study used artificial intelligence to compensate for such misreadings.
