Millions more people will be at risk of coastal flooding from climate-driven sea-level rise later this century.

That’s the conclusion of new research conducted by Climate Central, a US-based non-profit news organisation.

It finds that 190 million people will be living in areas that are projected to be below high-tide lines come 2100.

Today, the group calculates roughly 110 million are presently occupying these lands, protected by walls, levees, and other coastal defenses.

The future at-risk total assumes only moderate global warming and therefore limited ocean encroachment.
