This is the third year in a row that salt water from the Gulf of Mexico has crept up the Mississippi River. This phenomenon, known as salt water intrusion, previously only happened about once per decade.
Mayors along the Mississippi River have watched as intensifying rain storms and floods wreak havoc. This fall, the Mississippi River Cities and Towns Initiative announced a new pilot program to help river towns better recover.
A small earthquake brought tremors across the Tennessee, Kentucky and Missouri border earlier this month, a reminder that much of the Midwest sits on a major fault line, which saw one of the most destructive earthquakes in history in 1812.
Corona, Tennessee, is one of 35 border communities that, over time, have been cut off from their state by the Mississippi River. Located in unincorporated Tipton, it’s a two-hour drive from the rest of county.
Four species of Asian carp have firmly established a home in the Mississippi River basin, and experts say they are here to stay. But one way to get the carp population under control seems relatively simple — eat them.
Starting in late April, two major broods of cicadas will emerge together in the U.S. for the first time in 221 years. Memphis, however, won’t see cicadas outside of our normal ones until 2028.
“Since (this legislation) was first introduced (in 2021), the conditions of the world we live in just keep showing us that there is an urgent need to address these problems, and they’re not solving themselves,” said the executive director of the Mississippi River Network.
“We have some huge rainfall deficits that have built up, not only over the last year but the last few years,” said the director of the U.S. Department of Agriculture’s Midwest Climate Hub.
The upper Mississippi River is getting saltier but concentrations of most metals have decreased.
The past few years have brought wild fluctuations between flooding and drought, bringing more stress to the communities nestled along the Mississippi’s 2,350 miles.
But moving mountains of sand during historic low water levels creates its own problems.
The Mississippi River is a big deal. One of the world’s great rivers, it hosts an abundance of wildlife habitat and provides drinking water for almost 20 million people. But it seems to carry less reverence than other iconic water bodies across the country.
Within the contiguous U.S., temperatures have risen by 2.5°F since 1970, compared to a global average rise of about 1.7°F over the same period.

Since June, the Army Corps of Engineers has spent $38 million maintaining the Mississippi River channel, mostly through dredging the equivalent of 5,000 Olympic-sized pools of sediment.

“COVID really kind of kicked the baby boomers out,” said one industry insider, “and now that we had such a huge exodus of them, there’s just nobody to replace ’em.”
Unlike other pollutants, chloride doesn’t break down in water over time. In other words, once it’s in, there’s no getting it out — and just a teaspoon of salt can pollute five gallons of water forever.
PFAS are a class of more than 12,000 human-made compounds. They accumulate in the environment and human bodies over time and don’t easily degrade, which is why some call them “forever chemicals.”
While emissions from sectors such as energy production have fallen in the past few decades, those from agriculture — especially livestock and corn — are growing in most places.
A plume of chemical contaminants is traveling along the Ohio River at about one mile per hour and will eventually enter the Mississippi River.
Pumping water from the Mississippi River to drought-stricken western states is an option, but an expensive one.
