That sinking feeling: world's deltas subsiding, says study http://apocadocs.com/s.pl?1253552406
Two-thirds of the world's major deltas, home to nearly half a billion people, are caught in the scissors of sinking land and rising seas, according to a study published Sunday.
The new findings, based on satellite images, show that 85 percent of the 33 largest delta regions experienced severe flooding over the past decade, affecting 260,000 square kilometres (100,000 square miles).
Delta land vulnerable to serious flooding could expand by 50 percent this century if ocean levels increase as expected under moderate climate change scenarios, the study projects.
Worst hit will be Asia, but heavily populated and farmed deltas on every continent except Australia and Antarctica are in peril, it says.
On a five-tier scale, three of the eleven deltas in the highest-risk category are in China: the Yellow River delta in the north, the Yangtze River delta near Shanghai, and the Pearl River Delta next to Guangzhou.
