India’s coastal cities face an increasing risk of flooding, driven by a warming world and the now-frequent extreme weather events. While some cities are at a higher risk, this imperils the lives, livelihoods and critical infrastructure across the cities.
Globally, the mean sea level has risen by 20 cm since 1800, and is now rising at a rate of 3.22 millimetre (mm) in recent years. Estimates suggest this could increase by up to 1 metre (or 100 cm) by the end of this century.
