As China’s cities grow, they are also sinking.
In 100 years, a quarter of China’s urban coastal land could sit below sea level because of a combination of subsidence and sea level rise, according to the study.
“It’s a national problem,” said Robert Nicholls, a climate scientist and civil engineer at the University of East Anglia who reviewed the paper.
Dr. Nicholls added that, to his knowledge, this study is the first to measure subsidence across many urban areas at once using state-of-the-art radar data from satellites.
Subsidence in these cities is caused in part by the sheer weight of buildings and infrastructure, the study found.
