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.

The number of people at risk from coastal flooding could rise by more than 140 million by the end of the century as climate change causes sea levels to rise, a study has found. Around the world 267 million people live on land that is less than two metres above sea level, which is most at risk from rising seas and storm surges, according to research using lidar, a method of measuring elevation on the Earth’s surface using pulsed laser light. Scientists predict that by 2100, if the sea level has risen by a metre, that number will have increased to 410 million even without any population growth.
