Shanghai, the mainlands most populous city and an aspiring global financial centre, is also among the worlds most vulnerable urban areas to a rise in sea levels as global warming melts polar ice. Its location on a low-lying alluvial plain near the mouth of the Yangtze River, already makes it prone, but researchers warn that forests of skyscrapers sprouting across the metropolis could compound the threat by causing its marshy ground to sink. Researchers worry that the ground is being pushed down as masses of skyscrapers are plopped down across the urban landscape. There are about 10, 000 buildings of over 10 floors in Shanghai; 80 per cent have been built in the past 10 years, according to Emporis, a leading provider of building information.
