Melting Glaciers: Urban Flooding

China may have more glaciers than any other country. In one region alone it has 46,000. But the glaciers are melting and causing flooding. From 2008 to 2010, 62 percent of Chinese cities had floods; 173 had three or more. The glaciers are vital to more than a billion people in China, Vietnam, Myanmar and Bangladesh. But they are receding at a faster pace than ever. For example, from 2005 to 2014, the Mengke Glacier retreated an average of 54 feet a year, while from 1993 to 2005, it retreated 26 feet a year.
