Rising Sea Levels Threaten to Flood Southern Vietnam by 2100 Ralph Jennings HO CHI MINH CITY - It's not quite the first thing on everyone's minds in the booming financial center of Vietnam, but everyone kind of knows it might happen: Global sea levels pushed up by climate change threatens to flood the city by the year 2100. That threat resurfaced last week when U.S.-based nonprofit news organization Climate Central published a report in Nature magazine detailing timelines and locations for ever-rising seas. From 10% to one-third of Vietnam's population would be impacted, the Oct. 29 study says. Ho Chi Minh City, population 9 million, shows little outward concern for now. Cranes speckle the skyline to build new housing for the people who are steadily moving in from other parts of Vietnam for work or study. Ho Chi Minh City serves as an administrative center for the growing number of foreign-invested companies that manufacture goods in Vietnam for export, a source of 6%-7% annual economic expansion. But flooding regularly hits the populous, flat coastal regions just south of the city, making people keenly aware of what would increasingly happen if the adjacent South China Sea breaches its high tide line by 2100 as suggested by the report's author, Climate Central. "We do have to deal with climate change," said Do Van Chanh, 20, a third-year student at a Ho Chi Minh City University. .
