Rising seas threaten ‘mass exodus on a biblical scale’, UN chief warns

António Guterres calls for urgent action as climate-driven rise brings ‘torrent of trouble’ to almost a billion people

An increase in the pace at which sea levels are rising threatens “a mass exodus of entire populations on a biblical scale”, the UN secretary general has warned.

The climate crisis is causing sea levels to rise faster than for 3,000 years, bringing a “torrent of trouble” to almost a billion people, from London to Los Angeles and Bangkok to Buenos Aires, António Guterres said on Tuesday. Some nations could cease to exist, drowned under the waves, he said.
