Sixth year of drought in Texas and Oklahoma leaves ranchers facing wildfires and bracing for another tough year
Joel Lisonbee, University of Colorado Boulder and William Baule, Texas A&M University
Cattle auctions aren’t often all-night affairs. But in Texas Lake Country in June 2022, ranchers facing dwindling water supplies and dried out pastures amid a worsening drought sold off more than 4,000 animals in an auction that lasted nearly 24 hours – about 200 cows an hour.
It was the height of a drought that has gripped the Southern Plains for the past six years – a drought that is still holding on in much of the region in 2026.
The drought cost the agriculture industry across Kansas, Oklahoma and Texas an estimated US$23.6 billion in lost crops, higher feed costs and selling off cattle from 2020 through 2024 alone. As rangeland dried out, it has also fueled wildfires, including several in Texas in early 2026.
Historically, droughts of this magnitude happen in the Southern Plains about once a decade, but the severe droughts of this century have been lasting longer, leaving water supplies, native rangelands and farms with little time to recover before the next one hits.
Many cattle producers and rangelands were still recovering from a severe 2010-2015 drought when a flash drought hit western Texas in spring 2020, marking the beginning of the current multibillion-dollar, multiyear and multistate drought. Ample spring rainfall in 2025 and severe flooding in central Texas that year weren’t enough to end the drought, and a powerful winter storm in late January 2026 missed the driest parts of the region.
In a recent study with colleagues at the Southern Regional Climate Center and the National Integrated Drought Information System, we assessed the causes and damage from the ongoing drought in the Southern Plains.
We found three key reasons for the enduring drought and its damage: rising temperatures and a La Niña climate pattern; water supply shortages; and lingering economic impacts from the previous drought.
Weather and climate helped drive the drought
The Southern Plains is known to be a hot spot for rapid drought development, and the ongoing drought that started in 2020 is no exception.
Documented “flash droughts” – defined as periods of rapid drought onset or intensification of existing droughts – occurred at least five times in the region from 2020 to 2025. As global temperatures rise and climates warm, research warns that the frequency and severity of flash drought events will increase.
For the southern part of the Southern Plains, winter precipitation is closely linked to the El Niño–Southern Oscillation, a climate pattern that affects weather around the world. Five of the past six years exhibited a La Niña pattern, which typically means the region sees winters that are warmer and drier than normal.
La Niña was likely the primary driver – although not the only driver – of the drought for Texas and southwest Oklahoma, and one of the reasons drought conditions have continued into 2026.
The Southern Plains have a long history with severe droughts. The Dust Bowl of the early 1930s may be the best-known example. But a history with drought doesn’t make it any easier to manage when crops and water supplies dry up.
Deeply rooted water shortages
The heat and dryness since 2020 have left many of the region’s rivers, reservoirs and even groundwater reserves well below average.
San Antonio’s reservoirs all reached record-low levels in 2024 and 2025, as did the Edwards Aquifer, which provides water for roughly 2.5 million people. They were still low as 2026 began. Surface water and groundwater resources across central and western Texas have been depleted to the point that even a few big storms can’t replenish them.
A few major rivers flow into the Southern Plains from other drought-affected regions. Consider the Rio Grande, which begins in Colorado and winds through New Mexico and along Texas’ southern border: Not only has the Lower Rio Grande valley in southern Texas missed out on needed precipitation this winter, so did the Rio Grande headwaters in southern Colorado.
Colorado is facing a snow drought in winter 2026, as is much of the western U.S. If it continues, there will be less snowmelt come summer to feed rivers, such as the Rio Grande, or fill reservoirs. In early February, the Elephant Butte, Amistad and Falcon reservoirs, along the Rio Grande, were only 11%, 34%, and 20% full, respectively.
Lingering economic impacts
Like water supplies, the economy doesn’t just recover when the rains return.
One of the reasons the current drought has been so costly is that parts of the region had not fully recovered from the 2010-2015 drought when the latest one began in 2020. With only a five-year break between droughts, the landscape behaved like someone with an already weakened immune system who caught a cold.
During the 2010-2015 drought, cattle producers in Texas sold off about 20% of the statewide herd as water became scarce and rangeland dried up. Rebuilding a herd after a drought is a slow process. Pasture recovery can take a year or more, and a newborn heifer will take two years to mature and produce her own first calf.
Cattle herds had still not returned to pre-2010 levels when the 2022 drought peak forced another mass sell-off. From 2020 through 2024, Texas’s herd size declined from 13.1 million to 12 million; Oklahoma’s declined from 5.3 million to 4.7 million; and Kansas’ declined from 6.5 million to 6.15 million.

Looking beyond livestock, a large percentage of the Southern Plains’ crops failed in 2022, the peak year of the drought. In Texas, 25% of the corn crop was planted but never harvested, and 45% of the soybean crop was similarly abandoned. A normal season would have yielded a $2.4 billion cotton crop in Texas, but 74% of that crop was abandoned, slashing its value to roughly $640 million.
Ending the Southern Plains drought
Is the end in sight? With La Niña fading in early 2026 and its opposite, El Niño, potentially on the horizon, there’s a chance for wetter conditions that could reduce the drought in the fall and winter months of 2026.
But the Southern Plains still have to get through spring and summer first. Ending a drought like this requires consistent precipitation over several months, and drought conditions are likely to get worse before they get better.

Did Jackie Gleason See Aliens? Inside the Strange Nixon–UFO Legend
Jackie Gleason reportedly told his wife that President Richard Nixon arranged for him to view preserved extraterrestrial bodies at a Florida Air Force base. Here is what we know—and why the remarkable story remains unverified.
The beloved comedian reportedly told his wife that President Richard Nixon arranged for him to view preserved extraterrestrial bodies at a Florida Air Force base. Decades later, the extraordinary story remains fascinating—but unverified.
Jackie Gleason is remembered as “The Great One,” the larger-than-life entertainer who turned bus driver Ralph Kramden into one of television’s most enduring characters on The Honeymooners. Away from the cameras, however, Gleason had another consuming interest: UFOs, psychic phenomena and the possibility of extraterrestrial life.
That interest eventually became the foundation of one of the strangest stories ever associated with an American president and a Hollywood celebrity. According to Gleason’s second wife, Beverly McKittrick, her husband came home late one night in 1973 and claimed that President Richard Nixon had helped him see the preserved bodies of extraterrestrial beings at Homestead Air Force Base in Florida.
Did Jackie Gleason really see aliens?
The honest answer is that we do not know. The allegation is remarkable, but the available evidence never rises above an uncorroborated story attributed to Gleason years after the supposed event.
Gleason’s fascination with UFOs was real
There is little question that Gleason took the UFO subject seriously. He reportedly assembled a substantial personal library devoted to UFOs, the paranormal and related mysteries. His unusual circular home in New York—often nicknamed “The Mothership”—only strengthened his public association with flying saucers, although its distinctive architecture is not evidence of an extraterrestrial encounter.
Gleason also had a genuine social connection with Nixon. The two men shared an interest in golf and spent time together in Florida. That documented friendship is the factual starting point from which the more sensational story grew.
The alleged trip to Homestead Air Force Base
McKittrick said that Gleason returned to their Florida home at about 11:30 one evening looking disturbed. According to her account, he told her that Nixon had arrived without the usual presidential entourage and taken him to Homestead Air Force Base, south of Miami.
Once there, Gleason allegedly entered a secured building where he saw small humanoid bodies preserved inside glass-topped containers. Published versions differ over the number of bodies and some physical details, but they generally describe child-sized beings with oversized heads.
Importantly, McKittrick did not claim to have accompanied the men or witnessed anything at the base. Her account was based entirely on what she said Gleason told her after returning home.
The story became public in 1983, years after the alleged visit and after the couple had divorced. It circulated widely through tabloid reporting, UFO publications and later books, gradually becoming part of UFO folklore.
Why the story remains unverified
No authenticated photograph, visitor record, military document or firsthand statement from Nixon has emerged to confirm the alleged trip. Gleason also never provided investigators with a signed affidavit describing the experience.
UFO researcher Larry Bryant reportedly sought records from Homestead and tried to obtain a statement from Gleason, but those efforts produced no confirming documentation. Gleason’s refusal to address the account publicly has sometimes been portrayed as suspicious, but silence is not proof that an event occurred.
There is another important complication: McKittrick later expressed uncertainty about her former husband’s story.
During telephone interviews conducted by researcher Kenny Young in 2003, she stood by her recollection that Gleason told her he had seen “dead aliens.” She also acknowledged that, as the years passed, she wondered whether he might have invented the explanation because he had been out late. She declined to appear on camera and said the story should be authenticated first.
Her later comments do not establish that the account was false, but they considerably weaken any attempt to treat it as verified history.
Could a president have slipped away unnoticed?
Some versions of the legend emphasize that Nixon supposedly drove to Gleason’s house alone and then entered a military installation without his Secret Service detail. Presidents have occasionally sought privacy or slipped away from tightly managed schedules, but a secret nighttime excursion of this nature would have involved serious security and logistical obstacles.
The claim becomes even more difficult to accept when we consider what Nixon allegedly revealed. If the United States possessed extraterrestrial bodies, granting a comedian personal access to them would have represented an extraordinary breach of national security—with no apparent official purpose and no surviving documentation.
None of that makes the episode logically impossible. It does, however, mean that the story requires exceptionally strong evidence. That evidence has never appeared.
A compelling legend, not a confirmed encounter
The Jackie Gleason story endures because it combines three irresistible ingredients: a famous comedian fascinated by UFOs, a secretive American president and a nighttime visit to a military base containing an alleged government secret.
What can be established is that Gleason was deeply interested in UFOs, knew Nixon and was said by his former wife to have made an extraordinary claim. What cannot be established is that Nixon took him to Homestead Air Force Base or that preserved extraterrestrial bodies were ever stored there.
So, did Jackie Gleason see aliens?
Perhaps he believed that he did—or perhaps he simply told an unforgettable story. Until corroborating evidence emerges, the alleged encounter belongs in the intriguing borderland between celebrity history and American UFO mythology.

Lactose intolerance is actually the human norm – but racism, the US government and business interests have made it into a condition
Lactose intolerance is the global human norm, but Western dietary standards, government policies and commercial interests helped frame it as a medical deficiency.
Hilary Smith, University of Denver
Lactose intolerance makes drinking milk or eating ice cream a literal pain. For some people, eating a dairy treat can lead to bloating, nausea and diarrhea. You might’ve experienced its effects yourself. If so, you may think of lactose intolerance as a defect rather than the norm.
But did you know that most people in the world today are lactose intolerant – and that the condition itself was invented in the 1960s?
“Surely you mean discovered, not invented,” I hear you saying. I don’t. As a historian who has traced the origins of nutrition-science ideas, I have chosen the word “invented” on purpose.
Inventing lactose intolerance
Variations in people’s ability to digest lactose first came to scientists’ attention after American dairy producers found a way to rid themselves of a postwar milk surplus. To offload what they couldn’t sell, they looked to the government to intervene. And it did, buying the excess and embedding it in school lunches and other places with publicly funded meals.
Suddenly, many people who had not habitually drunk milk were consuming it regularly, including not only some Americans but also people overseas. Part of that same milk surplus found its way into school lunches in places such as Japan and Taiwan in the 1950s as the American government began to sell milk to allies during the Cold War.
Many of the groups drinking milk regularly for the first time did not like it. In fact, it made them feel sick. Intrigued, scientists set up experiments to figure out why. In a 1966 study comparing how Black and white people incarcerated in Baltimore metabolized lactose, researchers found that Black participants had lower levels of lactase – the enzyme that breaks down lactose – in their guts.
To the white scientists conducting this study, the trouble that the Black prisoners had digesting milk looked like an “inborn error of metabolism.” They assumed that the normal human state was lactose tolerance and that the lactose intolerant had inherited a genetic mutation.
It was only after years more work with research participants of many races that experts realized that, as one National Institutes of Health official put it in 1981, “lactose intolerance is a normal physiological condition, shared by every adult animal except for certain ethnic and racial groups in man.” People of northern European descent, it turned out, were the weird ones. It was their ancestors who had passed down a genetic mutation – one that made them able to digest milk after infancy.
In short, what scientists discovered in the 1960s was that different bodies process milk differently. What they invented was the idea that lactose intolerance is a defect. Accepting that framing would mean nearly two-thirds of the human population – the estimated prevalence of lactose intolerance worldwide – is defective.
Instead of acknowledging that dairy-free diets can be healthy, people innovated ways to overcome this supposed disability so everyone could consume more.
Nutritional imperialism
Lactose intolerance is one example of what I call nutritional imperialism: a way of thinking that treats white diets as the norm and everyone else’s as an aberration.
Nutritional imperialism was common in the 20th century, when scientists thought that not only milk-rich but also meat-heavy diets were best; they considered diets outside of the United States and Europe too vegetarian. Some also argued that wheat flour, not rice, ought to be the universal staple.
The same bias applied to bodies. Besides faulty lactose digestion, nonwhite bodies were accused of other failures, too, such as aldehyde dehydrogenase deficiency, an inability to digest alcohol quickly. The less technical term for this may be more familiar: Asian flush.
Such differences might have been thought of as variety, just another way of being human. Instead, each became a deficiency.
Many people today have inherited and perpetuated this way of thinking without knowing it, including those who are deemed deficient by it. In 1959, the director of Japan’s nutrition bureau declared that “rice-eating peoples” such as the Japanese were “resigned and passive” and could correct this by imitating Western diets and switching to wheat.
Today, the most prominent scientist promoting the idea that Asian flush is a disease is a geneticist of Taiwanese descent who started a research consortium to study “the most common human enzymopathy in the world.”
The Chinese Nutrition Society placed a tall glass of milk next to its 2022 Food Guide Plate – never mind estimates that the vast majority of Han Chinese, the largest ethnic group in China and worldwide, are lactose intolerant.
Turning sickness back into difference
Science that pathologizes difference helps racism persist.
In recent years, white supremacists have embraced the concept of lactose intolerance as a distinguishing debility of nonwhite people. Social media users have copied and pasted a map of the geographic distribution of lactose tolerance originally published in the scientific journal Nature into racist chat threads on the online discussion forum 4chan.
In 2017, internet trolls disrupted an anti-racist art installation with neo-Nazi chants and messily downed jugs of milk to accentuate their white identity.
Turning a lactose-digestion difference into a deficiency has done more to reinforce narratives of racial hierarchy than to improve public health. So here’s a suggestion: If you enjoy eating dairy, keep doing it; if you don’t, don’t – and know that there is nothing wrong with you.

FAA Certifies Boeing 737-7: What It Means for Airlines and the 737 MAX Program
The FAA has certified Boeing’s new 737-7, clearing the smallest 737 MAX variant for service as Boeing and Southwest prepare for first deliveries.
The U.S. Federal Aviation Administration has certified Boeing’s new 737-7, granting the company an amended type certificate that clears the smallest member of the 737 MAX family for commercial service. The milestone closes a multi-year certification effort and puts the focus on execution: Boeing and launch customer Southwest Airlines say preparations are underway to support first deliveries.
For STM Daily News readers, the headline isn’t just “another plane gets approved.” It’s a signal that Boeing has now cleared a key MAX variant designed for long-range flexibility in a smaller footprint—an aircraft type airlines can use to open or defend routes where demand is strong, but not strong enough to justify a larger narrowbody.
What FAA certification means
An amended type certificate means the FAA has approved the 737-7’s design as compliant with commercial aviation regulations. In practical terms, certification allows airlines to place the aircraft into revenue service once deliveries begin and operator-specific steps—training, manuals, maintenance programs, and entry-into-service planning—are completed.
Boeing also said the FAA updated Boeing Production Certificate No. 700 (PC 700) to include the 737-7, supporting production and delivery activities.
Why the 737-7 matters in the MAX lineup
Boeing positions the 737-7 as the smallest and longest-range member of the 737 MAX family. The company says it typically seats 135 to 160 passengers in a two-class configuration and offers a range of up to 3,800 nautical miles (7,040 km). That combination matters because it gives airlines more options to fly longer “thin” routes—markets where frequency and reach matter more than packing in additional seats.
Boeing also highlights performance for operations out of high-altitude airports and in hot climates, where takeoff performance and payload-range tradeoffs can shape fleet decisions.
Efficiency claims: fuel, emissions, and noise
Boeing says the 737-7, like other 737 MAX jets, reduces fuel use and CO2 emissions by 20% and cuts the noise footprint by 50% compared to the airplanes it typically replaces. For airlines, those improvements typically show up in two ways:
- Route economics: lower fuel burn can improve margins on longer sectors and reduce exposure to fuel-price swings.
- Operational constraints: quieter aircraft can help with airport noise requirements and community pressure, while lower emissions support sustainability targets.
Inside the certification effort
Boeing said the certification program began in 2018 and included more than 1,000 hours of flight and ground testing, extensive system safety analysis, and human factors reviews. The company also noted an updated engine anti-ice system to address a potential condition discovered during flight testing.
Boeing Commercial Airplanes President and CEO Stephanie Pope called the certification “important” validation of the airplane’s design and the work of the MAX development team. Mike Sinnett, senior vice president of Product Strategy, Product Development and Development Programs, said Boeing held regular discussions with the FAA and that the process has sharpened the company’s understanding of current regulatory requirements—knowledge Boeing expects will accelerate future development with a renewed emphasis on human factors, safety, and quality.
What to watch next
With certification complete, the next phase is about delivery timing and real-world deployment.
- First deliveries to Southwest: Boeing and Southwest are preparing for delivery of the first airplane, including updates to final configuration.
- Production stability: certification removes a major hurdle, but supply chain health and production cadence will determine how quickly the 737-7 shows up in airline schedules.
- The 737-10 timeline: Boeing reiterated it is working to certify the 737-10 this year, keeping attention on how quickly the final MAX variant clears regulatory review.
The bigger MAX picture
Boeing said the 737 MAX family order book stands at more than 7,200 airplanes, with more than 2,300 delivered through the end of June 2026. The 737-7’s certification adds another deliverable product to that portfolio—one aimed at airlines that want long range without stepping up to a larger gauge.
Bottom line
FAA certification of the 737-7 is a meaningful milestone for Boeing and for airlines looking for a smaller narrowbody with long-range capability. The real test now is operational: turning certification into on-time deliveries and reliable entry into service—while the industry watches Boeing’s push to certify the 737-10.
