Why extreme heat can force airlines to leave passengers behind
When the weather calls for heavy snow, thunderstorms or high winds in LAS VEGAS, airline passengers are aware that they may experience flight delays. On a sunny, hot day in the summer with no clouds above, it is harder to see the omens.
Extreme heat can also cause travel and flight disruptions. The thinner air on the hottest of days can hinder the safe takeoff and landing of aircraft. The airlines may need to reduce the weight of their aircraft by either removing cargo or passengers, or by carrying less fuel.
This problem is common at airports with desert climates all over the world, including the Southwest of the United States and the Middle East. Even airports that have shorter or higher runways, and are at higher altitudes can face similar problems. Climate change caused by humans could increase the frequency of such events.
Las Vegas showed how heatwaves can disrupt air travel. American Airlines compensated customers who gave up their seats voluntarily on a flight departing from Harry Reid International Airport in July after the temperature reached 114° Fahrenheit.
According to the airline, reducing a plane’s weight is a common industry practice when it comes to hot weather destinations. This ensures a safe and smooth takeoff. It’s all about physics.
Ross Aimer is a former United Airlines Captain and the CEO of Aero Consulting Experts. He explained that hot air is thinned out compared to cool air. This makes it more difficult for an aircraft’s wing to produce lift, and for its jet engine to create thrust for takeoff.
Aimer stated that there is science to all of this. You can’t ignore the science behind flight or what an aircraft needs to function.
The thin, hot air is a challenge for airplanes
Aimer compares high temperature on aircraft performance with athletes who compete at high altitude. The thinner air in Mexico City, located at more than 2,225 meters above sea level, meant that foreign teams participating during this year’s World Cup were more likely to be fatigued.
Aimer stated that jet engines, like humans, require a lot of dense, cool air in order to function properly.
Alan Price, retired Delta Air Lines Captain, explained that pilots determine if an aircraft is safe to takeoff by considering several factors. These include the weight of the plane, the elevation of the airport, and the temperature outside.
As the air is thinner at higher altitudes, temperatures do not need to rise as much to impact takeoff performance. Denver is located at a height of more than 1,524 meters (5,000 feet) above sea-level.
The length of the runway is also important. Price explained that shorter runways don’t give the aircraft enough room to accelerate for takeoff in high temperatures. Price said that airports like Washington Reagan National and New York LaGuardia can face more restrictions on takeoff or weight during hot weather.
When the pre-flight calculations show that an aircraft can’t safely leave as scheduled, airlines will reduce the cargo or carry less fuel, and refuel later. They may also wait until temperatures are cooler, or even ask passengers to volunteer to fly later.
There comes a time when weight loss is not enough to ensure a safe flight.
Aimer stated that “at some point the numbers don’t even make sense.” You could keep rolling down the runway for as long as possible, but you would still not be able to take off.
The hot weather can cause delays.
Federal Aviation Administration doesn’t set one maximum temperature to take off. The FAA states that operating limits are based upon the aircraft model and make, weight, and altitude of the airport.
Researchers from Columbia University’s Goddard Institute for Space Studies, NASA and the Logistics Management Institute conducted a study in 2017 that projected some airports would see weight restrictions for 10%-30% of flights leaving during the hotter part of the day if greenhouse gases emissions continue to increase. This study looked at 19 airports in the world. It found that those with shorter runways, higher elevations and warmer climates were most likely to be affected.
According to a more recent study, current climate models indicate that planes departing from four European airports will have to lose the equivalent weight of 10 passengers each flight by 2065.
Phoenix and Las Vegas are experiencing more hot days with temperatures in the triple digits.
The Associated Press analyzed weather station data and found that since 2020, Phoenix Sky Harbor International Airport averaged 43 daily days when temperatures reached 110 F. This number increased over several decades, before exploding in the 2020s and exceeding the mid-century average.
The AP found that temperatures at Harry Reid International Airport, Las Vegas reached this threshold on average 18 times a year, between 2020 and 2025. This is more than twice the average annual temperature during the 40s to 60s.
Palm Springs International Airport has also experienced extreme heat in the 2020s. This airport in Southern California recorded 55 average days per year with temperatures exceeding 110 F. That’s an increase of 83% compared to 2000s when data was first collected.
When weight is reduced, it’s for safety reasons.
Since years, airlines have been dealing with this issue. In June 2016, American cancelled several regional round-trip flights from Palm Springs, California to Phoenix during a period of intense heat. In the following year, American cancelled dozens of regional flight in Arizona when temperatures reached 120 F (49 C) in Phoenix.
KDVR reported that in July 2018 some airlines bumped customers at Denver International Airport onto later flights when temperatures reached 98 F.
Delta Air Lines asked volunteers in July 2023 to get off of a plane during an extreme heat alert in Las Vegas due to weight restrictions. The flight ended up being canceled because passengers had spent several hours in the extreme heat aboard the plane.
The urban heat island is a phenomenon whereby built-up zones become hotter than the surrounding area. Jennifer Brady, data scientist at Climate Central, explained that airports are particularly vulnerable.
Brady explained that the city’s central area is one of the most hot spots in the world. With no shade, little greenery, and vast areas of pavement that absorbs heat and the constant noise of airplanes, vehicles, and air conditioners that produce waste heat, the conditions are perfect for the space to be the hottest.

Whole Foods recalls foods in 12 states over salmonella risk
Whole Foods announced on Wednesday it was recalling some produce and foods prepared with fresh jalapenos provided by Coast Citrus Distributors due to possible salmonella contamination.
Food and Drug Administration stated that the products with “Best Before” date ranges from August 7 to 16 were sold across 12 states.
According to FDA, no illnesses were reported as a result of the Whole Foods recall.
Whole Foods announced that the recall covers select salsas and prepared food, including guacamole. The FDA website has a complete list of the affected products.
As the JALAPENO SALMONELLA outbreak sickens 345, 18 PREPARED FOODS ARE UNDER ALERT.
These products are sold in Texas and Oklahoma as well as Louisiana, Wisconsin, Michigan Illinois, Iowa Missouri, Arkansas Indiana Kentucky, Ohio, Wisconsin.
Whole Foods’ spokesperson stated that the recall on Wednesday was due to jalapenos in the product, which were purchased from Coast Citrus Distributors. The products are also linked with the recall of the distributor. Taylor Fresh Foods announced a recall on Sunday that included some of the same products.
Whole Foods’ action coincides with a larger salmonella outbreak that is linked to jalapenos and has hospitalized 345 individuals in 27 states.
Before Whole Foods’ announcement, a USDA alert on public health in Sinaloa (Mexico) had identified at least 18 meat and poultry ready to eat products distributed by Coast Citrus Distributors.
Nearly 30,000 pounds of RAW beef were recalled due to a missed import inspection
Taylor Farms announced on Monday a voluntary recall of jalapenos-containing prepared foods sold in Walmart, Whole Foods and other retailers across several states due to possible salmonella contamination.
The FDA reminded consumers to return any recalled Whole Foods product they purchased or to bring their receipts to Whole Foods Market for a refund.
Federal regulators say that illnesses associated with the jalapeno epidemic began between 2026 and June 19.

Ford boosts US Lincoln production as it phases out imports from China
Ford Motor Company has plans to increase U.S. Lincoln production beginning in 2030, and stop eventually importing cars from China for its American luxury customers.
Dearborn-based Ford said that this expansion will generate direct and indirect jobs in the United States for thousands. Ford has not disclosed how much money it intends to invest, or which plants will receive additional production.
This would be a major shift in Lincoln’s U.S. line-up, which includes currently the Nautilus built in China.
The Nautilus re-designed is built at Changan Ford’s plant in Hangzhou (China) and exported to America. Ford Oakville Assembly Plant, Ontario, Canada produced the previous generation.
Regulators warn that some older Ford vehicles pose ‘unreasonable’ safety risks.
Ford has not stated whether the Nautilus will be produced in the U.S. as part of its 2030 plan, or which China imported vehicles may be affected.
Ford, and other automakers in general, continue to face higher costs as well as uncertainty due to rising tariffs and shifting global trade policies.
Ford’s most recent annual report shows that tariffs implemented in 2025 will cost the company approximately $3 billion gross, and have an impact of approximately $2 billion on its earnings, before taxes, interest, and offsets.
Ford has not said whether trade concerns or tariffs were a factor in the decision to stop importing Lincolns from China.

Lincoln produces several vehicles in the United States. The Navigator, for example, is built at Ford’s Kentucky Truck Plant, located in Louisville. Meanwhile, the Aviator, which is manufactured at the Chicago Assembly Plant, is also produced by Lincoln. The vehicles are exported to Canada, Mexico, and the Middle East.
Ford will expand its already large U.S. production footprint with the additional production. Ford said that it would assemble more than two million cars in the U.S. by 2025. This is more than any other carmaker. It also leads the auto industry for U.S. vehicle imports and autoworker hourly employment.
Ford reports that it employs 56,300 manufacturing employees in the U.S.

Kroger closes at least 3 dozen stores across 9 grocery banners
Kroger closed more than 30 stores after announcing last year that it would close 60 outlets by 2026 if they did not deliver “sustainable results”.
Cincinnati’s grocery giant didn’t release an official list of all stores and banners that were to be closed, but searches on the internet revealed 39 sites across nine different banners no longer in operation. Local news reports confirmed that the majority of these locations are part of a larger store revamp.
According to a Securities and Exchange Commission (SEC) filing, as of January 2026 Kroger operated 2,697 grocery stores across 35 states, under approximately 20 different banners. These included Fred Meyer, Fry’s Food and Drugs, Harris Teeter and Jay C. Other brands include King Soopers and Mariano’s.
According to FOX26 Houston, the company stated that the closures were intended to “run our business more efficiently” and to ensure its long-term success. Two Houston area locations are scheduled to close by April.
In a $1.65 billion deal, KROGER will buy a popular grocery and pharmacy retailer.
Kroger, the national grocery retailer, announced last month that it would acquire Giant Eagle, a regional supermarket chain, for $1.65 Billion. This acquisition will add 197 additional stores and 11 independent pharmacies in northern Ohio, Western Pennsylvania, West Virginia and Indiana.
This acquisition will strengthen Kroger’s position in several Midwestern markets and Mid-Atlantic regions.
As part of Kroger’s consolidation efforts, at least three impacted stores were replaced or will be by Kroger Marketplaces. Kroger Marketplace is a larger format store that offers a wider selection of merchandise other than groceries, such as clothing, furniture, toys and homewares.

Bill Gates’ Daughter Knew For Months That Her App Claimed Sales It Didn’t Drive, Report Claims
Bloomberg published an investigation last month that claimed Phia was a startup founded by Phoebe Gates, daughter of billionaire Microsoft founder Bill Gates, and Sophia Kianni who is her Stanford roommate. They were engaging in unethical online practices.
According to the report, the web extension of this startup, which claims it can find better deals and discounts for online shoppers via cookie stuffing (which is against digital platform policies), had falsely claimed sales that were not generated.
It makes money from the retailers who pay it a commission for each sale it facilitates. To verify this, it drops a cookie in the browser of every shopper when they make a purchase that involves its extension. Bloomberg, Ben Edelman and Capital One Shopping, a rival company, claim to have conducted independent testing that found Phia’s app opens an unnoticed background tab in order to insert its affiliate code. This overrides other referrals so as to receive the commission. PayPal’s Honey was also accused of similar accusations in 2024. This led to a lawsuit filed by a group.
Phia’s representatives described the bug as such on July 8, telling Bloomberg the problem was only discovered “within 24 hours”. But a Bloomberg investigation has found that Phia executives and in particular Phoebe Gates were aware of this situation for at least 7 months prior to the publication of that report. They also actively encouraged the addition of these features.
Bloomberg reports that this issue is not a bug, but a controllable internal feature called “enable coupons auto drop”. Bloomberg cites anonymous Slack sources and internal Slack conversations to claim that Gates was in a Slack discussion with staffers back in December, and wanted to confirm that Phia dropped cookies across all websites even if a shopper didn’t use their coupon.
Reports also claim that Phia used other controversial practices. One feature included dropping cookies automatically every 2 hours for users who had interacted with Phia’s extension when visiting a “top 1000 websites.”
According to the internal communications presented by Bloomberg, an engineer tried telling co-founder Kianni that the practice could be “against compliance,” but Kianni allegedly responded with a Slack message saying: “I guess we could say that the user is trying to open us and roll it back if they complain.” Bloomberg reported that an engineer had tried to warn co-founder Kianni about the potential for the practice to be “against the law.” Kianni responded by sending a Slack chat message saying, “I suppose we could say the user was trying to open us, and roll it all back if the complainant.”
Kianni then responded with, “That’s great yeah whatever you can do to make these cookies keep falling will be awesome thank you.”
According to the report, after “coupon automatic drop” was disabled, Phia’s revenues plummeted from $80,000 down to $10,000-$28,000. This is based on an internal revenue chart.
Phia has denied all allegations made by Bloomberg. They also claimed that their revenue drop last month is solely the result of the reversed cookie stuffing. The company also hired a compliance head “to ensure that something similar never occurs again.”

Some Claude users are mad that Anthropic’s new watermarks will catch them using it at their jobs, classes
The company has decided to add a watermark (invisible code) into the text of the bot’s chatbot, which marks the output as AI generated.
This new policy was implemented by Anthropic to comply with the EU AI Act Transparency Code. The code requires that tech companies label AI-generated content or edits in a way computer systems can identify. While European regulators are happy with the new policy, AI users may not be.
Reddit is a great place to see the growing discontent. However, other users on the website aren’t in agreement. A user called visionode posted a post that was incredibly dramatic. His account has only been active for three weeks. Visionode claims that the watermarking scheme is an evil conspiracy to harm innocent chatbot users around the world.
Visionode appears to believe that while savvy Claude-users may be able to hide their AI usage through paraphrasing and other AI cleaning services, average Claude users will get caught.
Who will be caught? You. You. The journalist that asked the AI for a summary of a 200-page transcript. Writer who was stuck for words and requested synonyms. They come out with digital tattoos on their foreheads.”
It would be wrong of me to minimize visionode’s outrage. But those examples aren’t the most effective. If a journalist asks AI to sum up a 200-page transcript, they won’t care if there is a watermark on the summary unless that person copies and pastes it verbatim in their article. That is unethical.
The same is true for a student that copies and pastes Claude’s work into an essay, after having asked it to “reorganize a sentence.”
Redditors did not support the outrage of this poster.
One poster simply commented, “Get your hands on this guy.”
One person asked another to “take a deep breath”.
Visionode was not the only person to complain. One unhappy customer called the watermarks ‘unethical’ and a scumbag. They also claimed that Claude had already done most of the hard work. According to them, Claude was just a tool that aided their laborious work.
I gave the instructions and context. Claude did the rest. The poster asked: “If Claude watermarks the code, or any other thing it produces, for what is it claiming to be responsible?”
The critic was slammed by other users.
One user replied, “It isn’t claiming any credit.” It’s all about detecting AI-generated outputs due to the potential risks AI-generated outputs may cause.
Another joked, “Bro could not even write a complaint about Claude if Claude was not used to do it.”
Some critics avoided the narrative of victimhood and used slightly nuanced arguments to oppose Anthropic’s new policy.
One poster, for example, complained about the hypocrisy of watermarking a product editorial that had been created by stealing other people’s ideas. The user said, “I find it a sinister move.” I don’t write with Claude, but an AI watermarking your work seems a bit ironic considering how the Frontier models got their data.
