The John Caldwell2,340-mile-long Mississippi River is so low from hot, dry weather just a few months after severe floods helped replenish it from critically low water levels last year. 

A drought has heightened worries about a second year of costly shipping delays, which amassed to an estimated $20 billion in losses last year, according to AccuWeather. About 40 days of low water in parts of the Mississippi — which runs through or touches the borders of 10 states — grounded barges, stalled traffic, blocked river ports at the height of harvest season and revealed shipwrecks.

Cycles of drought and flood have always been a factor in the lives of people along the river, but climate change could drive wider swings and is generally expected to amplify those cycles.

According to a report from the Memphis Commercial Appeal, part of USA TODAY Network, the roughly 360-mile stretch between the Ohio River confluence to the north and the Arkansas River confluence to the south has been experiencing record water-level lows at several points, with more lows to come.
