Beneath the familiar story of rising seas lies a quieter crisis: the ground itself is giving way. Researchers from the Technical University of Munich and Tulane University have found that densely populated coastal regions are sinking two to three times faster than global sea levels are rising, driven not by climate alone but by the weight of human civilization pressing down on the earth beneath it. For more than half a billion people in low-lying coastal zones, the threat is not simply what the ocean is doing, but what centuries of extraction, construction, and settlement have done to the land

Over 500 million people living in low-lying coastal zones face accelerated flooding and displacement risks from combined sea-level rise and land subsidence.
