Chinese cities are sinking at 10 mm per year below sea level

A third of China's urban population is at risk of sinking below sea level, according to an analysis of satellite data that researchers say points to a global phenomenon.

China's urban area below sea level could triple in size by 2120, potentially affecting 55 to 128 million people, University of East Anglia researchers have announced.

They used satellite data to study 82 cities, including Shanghai and Beijing, with a total population of nearly 700 million people.

The team found that 45 percent of the urban land analyzed is sinking, and 16 percent is sinking at a rate of ten millimeters per year. "Hot spots" include Beijing and the coastal city of Tianjin, experts said.

The study estimated that 270 million urban residents could be affected. The findings were published in the journal "Science".
