More than 100 levees in 16 states are in an "unacceptable" state of disrepair
U.S. Army Corps of Engineers gives “unacceptable” maintenance ratings to 114 levees in 16 states; these levees are in such a bad shape, that it can be “reasonably foreseen” that they will not perform properly in a major flood; 30 of the levees are in Arkansas

Dire climate scenario: Mass migrations and war
Lord Nicholas Stern, the eminent economist, says severe climate shifts and sea-level rises would “transform where people can live”: “People would move on a massive scale. Hundreds of millions, probably billions of people would have to move if you talk about 4-, 5-, 6-degree increases” (7 to 10 degrees Fahrenheit)
