Delta Cities are at most risk identified a recent study

A study published recently in the journal Science says that a rise in sea-level, and gradual sinking of the Earth’s surface, have put delta cities at the risk of flooding. The world’s deltas are home to over 340 million people. This number is greater than the population of the entire United States.

Researchers used a suite of global datasets to estimate which deltas are at most risk. The deltas at highest risk are the Krishna and Brahmani in India, and the Ganges-Brahmaputra delta in Bangladesh. The image on your screen shows the loss of delta wetlands in Louisiana over the past four decades. You can see that significant parts of the land have been lost to the sea, leading to increased flood risk. The Mississippi delta in the United States, and the Rhine in the Netherlands, fall under the moderate risk zone.
