Millions face long-term coastal flooding risk in UK without climate action, scientists warn

A ‘reasonable worst-case scenario’ suggests need for large-scale movement of populations away from reshaped coast

Up to 13 million people in the UK face the long-term risk of coastal flooding due to the climate crisis, scientists have warned, with a “reasonable worst-case scenario” suggesting the need for the large-scale movement of populations away from a dramatically reshaped coast.

Even if today’s global pledges to cut carbon pollution are met, about 1.4 million more people will be exposed to coastal floods in 2200 and 1.7 million in 2300 due to the sea level rise driven by melting ice caps and warming oceans.
