“Of the world’s 33 major deltas, 24 are sinking, in large part due to human activity, and 85 percent experienced severe flooding in recent years, a new study finds.
“The flooding resulted in the temporary submergence of roughly 100,000 square miles of land. About 500 million people in the world live on river deltas.
“Using satellite data from NASA’s Shuttle Radar Topography Mission, which swept more than 80 percent of Earth’s surface during a 12-day mission of the space shuttle Endeavour in 2000, the researchers compared the SRTM data with historical maps published between 1760 and 1922.”
