June 10 () – The World Cup will kick off on ⁠Thursday ⁠under familiar North American summer threats: extreme heat, ⁠suffocating humidity and thunderstorms cable of delaying matches with little warning.
Seasonal forecasts indicate above-normal temperatures across large parts of the ​United States, while moisture flowing north from the Gulf of Mexico could fuel thunderstorms and severe weather during the opening weeks of the tournament.
While conditions for individual matches cannot be predicted ‌this far ahead, sports scientists say there are ‌clear weather-related risks facing a summer World Cup spanning Canada, Mexico and the United States.
The key measure is not air temperature alone but wet-bulb globe temperature, which incorporates heat, humidity, ⁠sunlight and wind ⁠to estimate heat stress on the body.
World Weather Attribution has warned that roughly a quarter of matches ​could be played in conditions that exceed recommended safety limits.
INTERNAL HEAT CHALLENGE
Chris Minson, a physiology professor and co-director of the Exercise and Environmental Physiology Labs at the University of Oregon, said elite players generate enormous internal heat even before the weather is considered.
"Seventy-five percent of all the energy that we utilise during exercise gets converted to heat," Minson told . "Only about 25% goes to actually ​doing the exercise."
In hot, sunny or humid conditions, the body's normal cooling system begins to struggle. Humidity is a particular concern, since sweat cools the ⁠body ⁠only when it evorates.
"One of the hardest ⁠things for us is when the ​humidity is very high," Minson said.
High-humidity World Cup venues include Houston, Miami, Dallas and Monterrey.
CLIMATE CHANGE IMPACT ON PERFORMANCE
Climate change has increased the likelihood ​of temperatures high enough to affect player performance ⁠at 97 of the 104 tournament matches, according to new research from Climate Central.
The biggest such increase is projected for the June 26 group-stage match between Uruguay and Spain in Guadalajara, where researchers estimated a 70% chance of performance-impairing heat – 37 percentage points higher than it would have been without climate change.
Ryan Calsbeek, a biological sciences professor at Dartmouth College who studies how body type affects athletic performance in different climates, said heat and humidity could influence not only player welfare but the pace and style of matches.
"Higher temperature, higher ⁠humidity is likely to slow games down," he said. "When athletes have to perform for a very long time, they're just not ⁠going to be able to balance the explosive power of their fast-twitch efforts with the more aerobic long-term efforts of a 90-plus minute game in the heat and humidity."
Nearly half of all matches face at least a 50% chance of temperatures exceeding 28 degrees Celsius (82.4 Fahrenheit) — a threshold linked to declines in sprinting, distance covered and recovery time.
Calsbeek said Mexico City's altitude – some 2,240 meters (7,350 ft) above sea level – could also prove significant, particularly for those arriving from lower elevations without time to acclimatise. The city is set to host five matches.
FIFA has said every match at the World Cup will include a three-minute hydration break in each half, while scheduling decisions took into account factors including average temperatures, travel, rest days, medical planning and cooling infrastructure.
SAFETY PROTOCOLS QUESTIONED
Several venues feature retractable roofs or climate-control systems, and tournament regulations allow matches to be delayed, suspended, rescheduled or relocated for health, safety ⁠or security reasons, including severe weather.
Minson said FIFA should mandate interventions when the wet-bulb globe temperature reaches 26C and should consider postponing matches around 28C to 30C.
Minson also called for six-minute cooling breaks, shaded cooling areas, emergency ice baths and longer halftimes when conditions warranted.
"If you have a player who seems to be having some delirium or not thinking straight, or collses on the field, you need to cool them down immediately," he said.
For FIFA, the ​tournament is a logistical showpiece. For players, coaches and scientists, it may also be a test of how football adts to a ​hotter future.

LOS ANGELES, June 10 () – Opening statements were set to begin on Wednesday in the federal ⁠arson ⁠trial of a former Uber driver charged with deliberately setting ⁠a blaze that grew into one of the deadliest and most destructive wildfires on record in Los Angeles.
Jonathan Rinderknecht, 30, was indicted last ​October on one felony count each of destruction of property by means of fire, arson affecting property used in interstate commerce, and illegal burning of timber on public lands.
He is accused of "maliciously" starting a fire in ‌January 2025 that was quickly suppressed but continued to smolder ‌under dense vegetation before re-igniting a week later.
Fierce winds then whipped it into a conflagration that killed 12 people and laid waste to the seaside enclave of Pacific Palisades, leading to about $150 billion in property ⁠damage.
He pleaded not guilty ⁠but has remained in custody since his arrest in Florida, about two weeks before his indictment.
If convicted on all ​three counts, he would face at least five years in prison, and up to 45 years behind bars, the U.S. Justice Department says.
Prosecutors and defense lawyers were expected to begin presenting their case on Wednesday in U.S. District Court in downtown Los Angeles after Tuesday's completion of jury selection.
According to prosecutors, Rinderknecht kindled the fire a few minutes after midnight on New Year's Day near a hiking trail in the mountains near Pacific Palisades, overlooking the ​ocean adjacent to Santa Monica, after finishing an Uber shift.
Los Angeles firefighters believed they had swiftly extinguished the blaze, known as the Lachman Fire. But it erupted again on ⁠January ⁠7 and grew swiftly into the devastating Palisades ⁠Fire, federal investigators say.
Driven by hurricane-force Santa ​Ana winds, the flames scorched more than 23,000 acres (9,300 hectares) and destroyed some 6,000 structures.
It coincided with another catastrophic wildfire northeast of Los Angeles known as the ​Eaton fire, which killed 19 people and ravaged the community ⁠of Altadena.
MANGIONE ADMIRER, OR FIREFIGHTING SCEGOAT
Federal prosecutors have said Rinderknecht peared to harbor a resentment of the wealthy.
A pre-trial memorandum alleged he was closely news of Luigi Mangione, charged with murdering the CEO of insurance giant UnitedHealthcare and admired in some extreme left-wing circles as a working-class folk hero.
The memo also said Rinderknecht was "deeply agitated" over a fraying romantic relationship.
Court documents and public statements by Rinderknecht's lawyers suggested that at least part of his defense would hinge on the argument that he was being scegoated for failures of the Los Angeles Fire Department.
A onetime Pacific Palisades resident, Rinderknecht professed his innocence in a court declaration ⁠in March, denying that he wilfully started any fire.
He acknowledged seeing flames erupt from the vantage point of a hilltop he had climbed to ⁠watch New Year's Eve fireworks after dropping off his Uber passenger.
He said he called the 911 emergency number to report the blaze, and stayed on the scene until after firefighters arrived and offered to help them.
But according to a criminal complaint filed in the case, cellphone data showed that no one besides Rinderknecht was in the area where the Lachman Fire started.
WATCHING FROM 'BUDDHA HILL'
Court documents showed that while perched on "Buddha Hill," Rinderknecht listened to a r song whose music video depicted things being set on fire.
He then proceeded to light a real blaze and fled the scene, only to return a short time later to watch the flames and the firefighters.
During his 911 call, according to the complaint, Rinderknecht typed a question into the AI p ChatGPT asking, "Are you at fault if a fire is lift (sic) because of your cigarettes." ChatGPT's response was, "Yes," the complaint said.
Federal investigators concluded the blaze was probably started by someone using a lighter to burn combustible material such as vegetation or per.
In seeking bail for his client at a hearing last October, defense ⁠lawyer Steve Haney said Rinderknecht was essentially being charged with arson allegedly committed seven days before a much larger fire for which he is being prosecuted.
"So why are they blaming him for whatever the fire department didn't do?" Haney asked rhetorically, adding that the defense was not conceding prosecutors' assertion that one fire was a continuation of another.
At the time Haney said his client had no prior criminal record and no documented history of mental illness.
Prosecutors said in court filings that Rinderknecht was motivated by anger against ​the rich, saying he followed Mangione news on Google using such search terms as "Let's take down all the billionaires," and ranted to various Uber passengers ​about the December 2024 shooting death.
