1440 - Nearly half of China's major cities are sinking, researchers say.  - The study, published in the journal Science, found 45% of China's urban areas are sinking over 3 millimeters per year, while 16% are sinking over 10 millimeters per year. The researchers used satellite data from 2015 to 2022 and said the cause of the sinking was partly due to the weight of buildings and groundwater extraction.
