270 million people are living on sinking land in China’s major cities, new study finds

CNN  

CNN — Land is sinking underneath millions of peoples’ feet in China’s major cities due to human activities, putting the country’s coastal areas more at risk of flooding and rising sea levels, new research shows. “Such massive coastal dike systems will largely reduce the risk of being inundated even given both land subsidence and sea level rise,” Tao told CNN. “Most urban cities experience land subsidence, but we focus our attention on coastal cities because of sea level rise,” Ohenhen, who was not involved with the study, told CNN. “However most urban cities experience land subsidence at rates comparable or even greater than subsidence in coastal cities.” Tao said the Chinese government is addressing the sinking in a few ways, including implementing strict laws to control groundwater pumping in the last few years.

The Hindu  

Across the world, many cities are slowly sinking. The problem is illustrated by a recent study by researchers in China which found that more than a third of the country’s urban population – some 270 million people – live in sinking cities. The authors analysed satellite-derived data from 2015 to 2022 across China’s 82 most important cities to produce accurate …

Coastal cities are sinking in the US and pushing sea level rise into overdrive

CNN  

CNN — Dozens of cities along the US coastline are sinking at alarming rates, leaving them far more exposed to devastating flooding from sea level rise than previously thought, scientists reported Wednesday. According to the researchers, this is the first study to combine the increasing threat of sea level rise with high-resolution measurements of sinking areas to determine which coastal …

Asian, tropical coastlines most vulnerable to rising seas: Study

India Today  

Tropical nations will face more coastal inundation from a rise in sea levels due to climate change than other countries, according to new research that also more than doubles the number of people estimated to be impacted. Using land elevation data gathered by laser pulses beamed by satellite to Earth, scientists identified coastal areas low enough to make them vulnerable …
