Rising Seas Stretch Risk Zones

Using updated CoastalDEM elevation data and IPCC medium-to-high emissions scenarios, Climate Central projects that by 2100, annual coastal flood risk zones will expand to include areas where an additional 93 million people currently live. The report highlights severe population impacts in Asia, particularly in China, Bangladesh, and Vietnam, and provides the first full assessment of population exposure in Arctic nations.

• By the end of the century, coastal flood risk zones are projected to extend further inland and higher, affecting areas where 93 million people currently reside.
• China faces the largest absolute increase in population exposure, with the number of people in the annual flood risk zone projected to grow from 52.5 million in 2030 to 81.7 million by 2100.
• Several other Asian nations show significant increases in population exposure by 2100: Bangladesh (30.4 million), Vietnam (25.6 million), India (24.2 million), Indonesia (16.8 million), and Japan (12.7 million).
• The report provides the first comprehensive assessment of population exposure in Arctic nations, noting that by 2100, Russia will have 469,000 residents in the annual flood risk zone, followed by Denmark (224,000) and Canada (325,000).
• The analysis utilizes CoastalDEM version 3.1, an AI-driven digital elevation model updated in March 2024, combined with IPCC SSP3-7.0 medium-to-high emissions scenarios.
