President Joe Biden announced Wednesday that federal disaster assistance is available for Louisiana, which is working to slow a mass inflow of salt water creeping up the Mississippi River and threatening drinking water supplies in the southern part of the state.
Biden's action authorizes the Department of Homeland Security and the Federal Emergency Management Agency to coordinate all disaster relief efforts, according to a news release from the White House. Additionally, the declaration will allow for more equipment, resources and federal money to address the saltwater intrusion.
“I’m grateful to the Biden administration for making this request a priority and responding quickly to help the people of South Louisiana,” Louisiana Gov. John Bel Edwards said in a news release Wednesday.
For the second year in a row, salt water from the Gulf of Mexico has moved further up the Mississippi, threatening drinking water in communities that rely on the river for fresh water. Typically, the river’s mighty flow keeps mass amounts of salt water from reaching too far inland, but hot and dry conditions across the country this summer triggered drought that slowed the Mississippi’s flow and lowered its water levels.
In parts of Plaquemines Parish, the southeast corner of Louisiana encompasses the final stretch of the Mississippi River before it reaches the Gulf of Mexico, residents have relied on bottled water for cooking and drinking since June.
Drinking water advisories have been issued for some communities in the parish, warning people the water is unsafe to drink, especially for people with kidney disease, high blood pressure, those on a low-sodium diet, infants and pregnant women.
Now the salt water is moving further upriver and will likely reach Orleans, St. Bernard and Jefferson parishes by mid-to-late October, officials say.
Edwards wrote to Biden earlier this week to ask for federal help. In his letter, Edwards said that the issue “is of such severity and magnitude” that state and local authorities can no longer manage it on their own. Federal assistance is “necessary to save lives and to protect property, public health and safety or to lessen or avert the threat of a disaster,” the governor wrote.
While officials say they are praying for rain to help increase the velocity of the drought-stricken river they are also taking matters into their own hands — raising the height of an underwater levee used to block or slow the salt water and bringing in 15 million gallons of fresh water to treatment facilities in impacted areas.
Satellite launch service Virgin Orbit has gone public on the Nasdaq via a SPAC merger with NextGen Acquisitions with a valuation of about $3.2 billion. CEO Dan Hart joined Cheddar's "Between Bells" from in front of his LauncherOne rocket in New York City's Times Square to talk about what's next after the IPO, an upcoming "Above the Clouds" mission to deliver commercial and national security payloads, and the benefits of their rockets being launched from commercial 747 aircraft. "We can launch anywhere in the world," he said. "There are almost 80 space agencies across the world, for instance, and about 10 of them have space launch. We can give them a space flight capability overnight by taking a runway and turning it into a spaceport."
The year 2021 saw numerous natural disasters around the world, including extreme heat and wildfires, rare deep freezes, and historic flooding. This year's United Nations COP26 conference was key for getting world leaders on board with emissions reductions and other climate-focused policies as the UN Secretary-General said the agency's report on global warming is a 'code red for humanity.' In the U.S., President Joe Biden has focused most of his domestic agenda on slashing emissions and building climate-focused infrastructure. Guests from The Economist, UNC-Chapel Hill, Global Rescue, and more join Cheddar Climate's year-end special to discuss how the climate changed in 2021, and what to expect in 2022.

Among all the other events of the last few years, you may have missed this one: Spermageddon. This is the fun name for the idea that sperm counts among mainly ‘Western’ men are in freefall. The Spermageddon hype began with the publication of a 2017 study showing a nearly 60% drop in overall sperm counts in men living in North America, Europe, Australia, and New Zealand.
But four years later, it seems that Spermageddon has been overblown. By a lot. And all that hype has obscured the real issue behind declining male fertility.

Each year about 5,000 people are diagnosed with ALS. This is such an important conversation. A disease that can weaken a patient's muscles and impact physical function. However, one research company says that could all change soon. Coya Therapeutics has developed a way to isolate a patient problematic T-cells in order to help ultimately slow the decline of not just ALS, but potentially Alzheimer's and other neurodegenerative diseases as well. Founder and Chief Executive Officer at Coya Therapeutics, Dr. Howard Berman, joined Cheddar to discuss more.
In the fight against climate change, much of the conversation revolves around reducing greenhouse gases like carbon dioxide or methane - and attempting to raise oxygen levels. But there's another gas - hydrogen - that could play a big role in the fight for the climate. Marco Alvera, CEO of Italian energy infrastructure company Snam and author of the book, 'The Hydrogen Revolution,' joined Cheddar Climate to explain the role hydrogen plays in helping achieve a net-zero future.
Americans looking to purchase at-home COVID-19 tests will now have to shell out a bit more money after an agreement expired between the White House and companies to sell the tests at cost. The price of Abbot's BinaxNow test kit from October to December was $14 apiece; on Tuesday, Walmart's website listed the test for $19.88, and Kroger listed the tests for $23.99. Carbon Health Regional Clinical Director Dr. Bayo Curry-Winchell joined Cheddar News' Closing Bell to discuss the impact higher prices will have as the nation experiences another surge in cases.
As millions of kids go back to school, districts across the country are determined to keep class in person, despite a surge in COVID cases.
