Sea level rise threatens larger number of people than earlier estimated

More people live close to sea coast than earlier estimated, assess researchers in a new study. These people are the most vulnerable to the rise of the sea level as well as to the increased number of floods and intensified storms. By using recent increased resolution datasets, Aalto University researchers estimate that 1.9 billion inhabitants, or 28% of the world’s total population, live closer than 100 km from the coast in areas less than 100 meters above the present sea level.

  • By 2050 the amount of people in that zone is predicted to increase to 2.4 billion, while population living lower than 5 meters will reach 500 million people. Many of these people need to adapt their livelihoods to changing climate, say Assistant Professor Matti Kummu from Aalto University.
