(TIME) — Global sea levels could rise by much more than previously predicted, according to new study.
Global sea levels could rise by almost 6ft – twice as much as had previously been predicted – a May 20 study warns
The implications for coastal populations around the world could be severe if the predictions in the study in the Proceedings of the National Academy of Sciences prove accurate. In the worst-case scenario, where global emissions are not curtailed and the climate warms by 5°C (9° Fahrenheit), the report authors predict sea levels could rise by as much as 7.8 feet.
Large parts of low-lying countries like Bangladesh would become uninhabitable, while critical areas for food production would be lost. Major cities, including New York and London, would also be threatened, according to the study.
