Sea level could rise

Global Sea Levels Could Rise by Much More Than Previously Predicted, According to New Study

Global sea levels could rise by over 6 feet by 2100––twice as much as had previously been predicted––threatening major cities and potentially flooding hundreds of millions of people, a study published Monday warned.

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.
