Up to 410 million people at risk from sea level rises – study

Majority of land at risk from a 1-metre sea level rise is in the tropics, research finds

Up to 410 million people will be living in areas less than 2 metres above sea level, and at risk from sea level rises, unless global emissions are reduced, according to a new study.

The paper, published in Nature Communications, finds that currently 267 million people worldwide live on land less than 2 metres above sea level. Using a remote sensing method called Lidar, which pulsates laser light across coastal areas to measure elevation on the Earth’s surface, the researchers predicted that by 2100, with a 1 metre sea level rise and zero population growth, that number could increase to 410 million people.
