Coastal Subsidence
Sea levels rise faster than in 4,000 years around China's coasts
Scientists have found that global sea levels are climbing more quickly than at any time in the past 4,000 years, posing severe risks to China's major coastal cities. The rapid rise, driven by warming oceans and melting ice, combines with land subsidence from human activities like groundwater pumping. Cities such as Shanghai are implementing measures to stabilize the ground amid these threats.
