Rising Seas Threaten Millions in U.S. Coastal Cities by 2100

A US Geological Survey study warns that by 2100, rising sea levels and land subsidence could severely impact US coastal cities, affecting over 14 million people and causing over $1 trillion in property damage. The East Coast, including cities like Miami and New York, faces significant threats from flooding and sinking land, while California's San Joaquin Valley is experiencing record subsidence due to excessive groundwater extraction. Researchers emphasize the need for strategic planning and resilience strategies to mitigate these effects, though specific solutions were not detailed.
