  • Players, enthusiasts in New York mark 55th anniversary of Ping-Pong Diplomacy

    Players, enthusiasts in New York mark 55th anniversary of Ping-Pong Diplomacy

    On a crisp Friday in Manhattan, a diverse crowd of table tennis competitors, enthusiasts, and diplomatic figures filled SPIN New York Flatiron to commemorate a half-century of a people-to-people exchange that fundamentally altered the trajectory of China-US relations: the 55th anniversary of Ping-Pong Diplomacy.

    The event brought together a cross-section of global table tennis talent and community members, ranging from former United States national champions and a former Swedish national team competitor to amateur community players, college athletes, and legal and finance professionals who share a passion for the sport. All joined in honoring the small, accidental moment that opened a new chapter in bilateral ties five and a half decades ago.

    In her opening remarks at the celebration, Chen Li, China’s Consul General in New York, walked attendees through the unexpected origins of the historic diplomatic breakthrough. Fifty-five years earlier, an American table tennis player accidentally stepped onto the Chinese team’s bus during the 1971 World Table Tennis Championships in Nagoya, Japan. What began as a simple misstep quickly bloomed into an unplanned friendly exchange, sparking the series of interactions that became known as Ping-Pong Diplomacy and clearing the path for the first official visit by an American sports delegation to the People’s Republic of China.

    Chen recalled the enduring Chinese sports motto, “Friendship first, competition second,” noting that even in that first encounter, American athletes observed that Chinese spectators cheered for every outstanding shot, no matter which side scored the point. “They realized that rivals had become friends overnight. Few could have imagined that a friendly paddle volley would help turn the wheel of China-US relations,” Chen told the gathered crowd.

    Reaffirming the core role of ordinary people in shaping bilateral ties, Chen emphasized, “The foundation of our relations was built by the people, and its future rests with our youth. You are all ambassadors of friendship.”

    Across the club’s tables, players from every cultural background and skill level competed side by side, carrying on the spirit of exchange that defined the 1971 breakthrough. Among the attendees was Rory Hayden, who was just 20 years old when she served as a translator for the Chinese table tennis delegation during their historic first visit to the United States in 1972, bringing a direct personal link to the history the event honored.

  • Madonna joins Sabrina Carpenter to surprise Coachella

    Madonna joins Sabrina Carpenter to surprise Coachella

    One of the most iconic figures in pop music history delivered an unexpected thrill to thousands of Coachella Valley Music and Arts Festival fans over the weekend, when Madonna made a surprise guest appearance during Sabrina Carpenter’s headlining Friday set. The legendary Queen of Pop joined the rising pop star on stage for a high-energy joint performance that included hits spanning Madonna’s decades-long career, plus a sneak peek of new material from her upcoming project.

    Rumors of Madonna’s potential appearance at the Southern California desert festival had swirled across social media for days before the set, sparking intense fan speculation. Just two days ahead of the performance, the singer made a major official announcement: she is set to release *Confessions II*, the long-awaited sequel to her critically acclaimed 2005 dance-pop album *Confessions On A Dance Floor*.

    After Carpenter wrapped up her performance of the fan-favorite track *Juno*, the opening notes of Madonna’s 1990 genre-defining hit *Vogue* began to echo across the Empire Polo Club grounds. Dancers launched into the song’s iconic posed choreography as Madonna emerged to a roar of crowd approval. Matching in coordinated blonde hairstyles and lace corset ensembles, the two stars delivered a dynamic duet of the timeless house hit, before strutting together across the main stage to perform a never-before-heard track reportedly taken from Madonna’s forthcoming new album.

    In a warm on-stage exchange, Madonna told Carpenter, “Thank you so much for inviting me on your show.” Carpenter responded instantly with heartfelt praise: “No thanks needed, Madonna. You can have whatever you want.”

    Addressing the packed crowd directly, Madonna reflected on a meaningful career milestone that tied her current appearance to her history at the iconic festival. “Twenty years ago today, I performed at Coachella – I was in the dance tent and it was the first time I performed *Confessions On A Dance Floor: Part I* in America and that was such a thrill for me,” she shared. “So you can imagine what a thrill it is for me to be back 20 years later… so it’s a like a full circle moment you know – very meaningful for me.” After a lighthearted chat with the audience about astrology, the 66-year-old pop icon joked that the collaboration marked the first time she has ever performed with an artist shorter than her, quipping “Thank you for giving me that experience” to laughter from the crowd.

    The pair closed their joint set with a powerful duet of Madonna’s seminal 1989 hit *Like A Prayer*, sending fans into a frenzy on social media after the performance.

    This surprise set marks Madonna’s third notable appearance at Coachella across the decades. She first made history at the festival in 2006, when she dropped in for an unannounced set in the Sahara Tent to debut material from the original *Confessions On A Dance Floor*. She returned again in 2015 for a guest spot during Drake’s headlining set, which spawned a viral cultural moment when she kissed the rapper mid-performance.

    For Carpenter, the collaboration marks another high-profile guest addition to her landmark first turn as a Coachella headliner. During the first weekend of the two-weekend festival, she was joined on stage by beloved comedian Will Ferrell for a memorable cameo.

    Running annually at Indio’s Empire Polo Club since 2002, Coachella is one of the largest and most high-profile music festivals in North America. Local law enforcement data confirms the festival draws more than 100,000 attendees each day across its two weekends. Following Friday’s pop-heavy headline set, the festival schedule will see Justin Bieber take the main stage as Saturday’s headliner, with Colombian global pop star Karol G closing out the second weekend on Sunday.

  • Haiti crisis worsens as nearly 6m face acute food insecurity

    Haiti crisis worsens as nearly 6m face acute food insecurity

    PORT-AU-PRINCE – A grim new UN-backed assessment published Thursday has laid bare the accelerating collapse of food security in Haiti, confirming that nearly 6 million Haitians will grapple with life-threatening acute hunger in the coming months. The findings underscore how persistent gang violence, mass internal displacement, and crippling economic instability have pushed the small Caribbean nation into one of the world’s worst ongoing humanitarian catastrophes.

    Per the Integrated Food Security Phase Classification (IPC), the international body that tracks global food insecurity, 5.8 million Haitians – accounting for more than half of the country’s total population – are currently classified as facing acute food insecurity. Of this vulnerable group, over 1.8 million have already reached the emergency hunger phase, requiring immediate life-sustaining food assistance to avoid widespread malnutrition and mortality.

    The IPC report attributes the deepening crisis to three interconnected drivers: rapidly deteriorating public security across the country, cascading economic shocks, and repeated breakdowns of local food markets and agricultural activities. Armed gang factions have expanded their territorial control across large swathes of Haiti in recent months, disrupting supply routes, forcing farming communities to abandon their lands, and displacing more than 1.4 million people internally. This mass displacement has stretched already limited local food supplies thin, pushing low-income and vulnerable households into extreme levels of hunger.

    While the latest IPC projection marks a small downward revision from an earlier forecast of 5.91 million acutely food-insecure people, humanitarian agencies caution that any minor progress remains extremely fragile. Analysts attribute the slight improvement to a combination of targeted international food assistance, easing national inflation rates, and better-than-expected harvests in a handful of Haiti’s agricultural regions. The United Nations World Food Programme (WFP) confirmed that consistent, sustained food aid interventions have lifted roughly 200,000 Haitians out of emergency-level hunger since last year.

    Still, aid leaders warn that these fragile gains are at immediate risk of reversal without a significant expansion of international support. In particular, the recent spike in global fuel prices triggered by ongoing tensions around the Iran conflict has driven sharp increases in transportation and agricultural production costs across Haiti, placing additional strain on humanitarian operations and household budgets.

    “Fighting hunger is essential to restoring stability in Haiti. We cannot build peace if families cannot feed their children,” Wanja Kaaria, WFP’s Country Director for Haiti, said in an official statement, emphasizing the urgent need for scaled-up global backing to prevent the crisis from spiraling further out of control.

  • Fuel price rise adds to US dilemma on Chinese EVs

    Fuel price rise adds to US dilemma on Chinese EVs

    Escalating geopolitical tensions in the Middle East have sent global oil prices surging in recent months, creating a sharp, uncomfortable policy dilemma for Washington: rising fuel costs are driving growing consumer demand for affordable electric vehicles, but long-standing US trade barriers continue to block Chinese EV brands that could meet that demand.

    The global benchmark Brent crude climbed 4.7% to settle at $99.39 per barrel this Thursday, a sharp jump from the roughly $70 per barrel price point that held before the Iran conflict intensified in late February. The run-up in crude has pushed retail gasoline prices higher across the United States, making the lower operating costs of electric vehicles far more attractive to cost-conscious car shoppers.

    For years, the US federal government has locked Chinese-made passenger vehicles out of the domestic market through steep tariffs that exceed 100%, with official justifications centered on protecting domestic manufacturing jobs and addressing unsubstantiated national security risks. A 2025 regulatory rule went even further, banning the import and sale of connected vehicles and critical automotive components with ties to China. Nand Mulchandani, a visiting fellow at Stanford University’s Hoover Institution, points out that intense lobbying from domestic industry groups has been a core driver of these restrictions, noting US legacy automakers have continuously pressured the Biden administration to secure artificial competitive advantages in the domestic market.

    Despite the political and regulatory headwinds blocking their entry, data shows large segments of US consumers are eager for access to Chinese EV brands, drawn by their combination of competitive pricing, innovative features, and strong overall value. A Cox Automotive survey of 802 US consumers planning to purchase a new vehicle within the next two years, conducted between December 29 and January 2, found that 49% of respondents rated Chinese vehicles as offering very good or excellent value for money. Forty percent of all survey participants said they supported allowing Chinese auto brands to enter the US market, with that number jumping to 69% among younger, more demographics.

    The high cost of new vehicles in the US has only amplified this consumer demand. For nearly a year, the average transaction price for a new vehicle in the country has hovered around $50,000, pushing a growing share of buyers to seek lower-cost alternatives that Chinese manufacturers are uniquely positioned to provide. Joanna Stern, senior personal technology columnist at The Wall Street Journal, highlighted this gap in a January 29 column after testing Chinese EVs, noting that leading manufacturers including Xiaomi, BYD and Geely have earned global recognition for delivering longer battery ranges and deeply integrated, user-friendly digital platforms.

    “We’re talking software that feels smooth like a brand-new smartphone, not a screen you have to jab five times to load a map. Plus, they often cost tens of thousands of dollars less than Western competitors. In Europe and Mexico, they’re blowing past Tesla and other EV rivals,” Stern wrote in her column, titled I Test Drove a Chinese EV. Now I Don’t Want to Buy American Cars Anymore.

    That assessment is echoed by EV enthusiasts on social platforms. On Reddit’s popular r/electricvehicles forum, users frequently highlight that Chinese electric vehicles offer premium features including luxury seating, customizable ambient lighting, and intuitive infotainment systems at their price points, delivering far better value than many Western brands. Many commenters note that Chinese EVs’ performance, high-end interior finishes, advanced connectivity, and driver-assist systems match or even exceed those offered by market leader Tesla.

    Yet while consumer sentiment has shifted sharply in favor of greater access to Chinese EVs, the position of US auto industry leadership remains dramatically opposed. Last month, major US auto trade groups sent a formal letter to the White House urging the administration to maintain the full ban on Chinese automakers’ entry into the US market, citing competitive fairness concerns, per a report from Reuters. Notably, President Donald Trump struck a more moderate tone during a January appearance in Detroit, saying he would be open to Chinese automakers establishing domestic manufacturing operations in the US as long as those facilities employed American workers.

    Some automotive industry analysts argue that blocking Chinese EVs entirely is short-sighted, and that US manufacturers could learn critical lessons from China’s agile production model. Steve Greenfield, founder and CEO of automotive technology advisory firm Automotive Ventures, observed that Chinese automakers have compressed development timelines dramatically: new models can move from concept to full production in as little as 18 to 24 months, roughly half the average timeline for many legacy Western manufacturers. Greenfield added that Chinese manufacturers achieve this faster pace while maintaining consistent quality, keeping production costs low through advanced automation and optimized supply chains.

    Greenfield told Automotive News that US legacy automakers would benefit greatly from understanding how Chinese firms deliver affordable, high-quality EVs so quickly, and that strategic cross-border partnerships could deliver widespread gains for the US industry. For his part, Mulchandani noted the ultimate future of Chinese EVs in the US market will depend on a broader policy calculation of costs and benefits for the country as a whole. “If the government does the calculations and thinks that this would be net good for the country and for the consumers, I’m sure they’ll make the right decision,” Mulchandani told China Daily.

  • What is the Fisa law Trump wants extended and why are lawmakers resisting?

    What is the Fisa law Trump wants extended and why are lawmakers resisting?

    After weeks of stalled negotiations over a long-term renewal of the U.S. government’s top foreign surveillance authority, Congress has approved a last-minute 10-day extension of the Foreign Intelligence Surveillance Act (FISA) to avert an imminent expiration, leaving core debates over surveillance policy and civil liberties unresolved. Enacted in 1978, FISA laid the foundational framework for regulating foreign intelligence gathering activities conducted by U.S. agencies, requiring oversight from a dedicated judicial body and compelling cooperation from domestic telecommunications providers. The law operated largely without public controversy for decades, but its addition of Section 702 in 2008 transformed it into a flashpoint for bipartisan criticism over the expansion of domestic warrantless data collection. Section 702 grants the National Security Agency (NSA) explicit authority to collect electronic communications of non-American citizens located outside the United States, but critics have long highlighted that the provision also allows agencies to incidentally sweep up vast volumes of personal data belonging to U.S. citizens who communicate with targeted foreign individuals. The American Civil Liberties Union (ACLU) has emerged as a leading critic of the policy, arguing that Section 702 enables mass, unwarranted surveillance of all forms of digital communication, and that improperly collected data is often used to prosecute individuals for crimes entirely unrelated to national security. Supporters of the provision, including senior national security and law enforcement officials, defend it as an irreplaceable tool for counterterrorism, counterespionage, and transnational crime enforcement. They contend that requiring case-by-case warrants for every data query would slow critical investigations, hinder efforts to identify potential threats and victims, and drastically reduce operational efficiency. Recent attempts to pass a five-year reauthorization of the existing law failed in the House of Representatives, split over demands from cross-party reform lawmakers to close the so-called “backdoor search” loophole that allows agencies to query already-collected U.S. person data without a warrant. With the original law set to expire on Monday, both the House and Senate voted unanimously on Friday to extend the statute through April 30, buying additional time for negotiations between lawmakers and the Trump White House. The Trump administration has taken a contradictory position on FISA reform: President Trump has repeatedly claimed he was the victim of unlawful FISA abuse during his 2016 and 2020 presidential campaigns, but in recent days he has reversed his earlier skepticism and pressed congressional Republicans to support an 18-month, reform-free extension of the law. Trump argued that Section 702 is critical to U.S. military operations, particularly following recent American actions in Venezuela and Iran, and posted on social media that he would willingly sacrifice his own civil liberties to support the policy. Bipartisan opposition to the administration’s demand remains solid, however, with lawmakers from both major parties rejecting a clean extension on the grounds that it would codify indefinite warrantless surveillance of U.S. citizens. Senate Majority Leader John Thune has acknowledged that reform is on the table during ongoing negotiations, but has declined to offer concrete guarantees that changes to the surveillance provisions will be included in the eventual long-term extension bill.

  • White House and Anthropic set aside court fight to meet amid fears over Mythos model

    White House and Anthropic set aside court fight to meet amid fears over Mythos model

    A surprising shift in relations between the Trump White House and leading artificial intelligence developer Anthropic has unfolded, with senior administration officials holding a “productive and constructive” meeting with Anthropic CEO Dario Amodei — even as the AI firm continues its legal battle against the U.S. Department of Defense.

    The high-stakes sit-down, which took place on Friday, brought Amodei face-to-face with Treasury Secretary Scott Bessent and White House Chief of Staff Susie Wiles, according to reporting from Axios. The gathering comes just one week after Anthropic launched the public preview of its latest cutting-edge AI system, Claude Mythos, a tool the company says exceeds human performance in a range of specialized hacking and cybersecurity tasks. To date, access to Claude Mythos has been restricted to only a small group of vetted organizations, but independent cybersecurity researchers have already confirmed the system’s unusual capabilities, describing it as “strikingly capable at computer security tasks.” Per Anthropic’s own documentation, Claude Mythos can independently detect hidden vulnerabilities in decades-old legacy code and autonomously develop working methods to exploit those flaws.

    This new overture from the White House marks a dramatic reversal from just two months ago, when the Trump administration publicly derided Anthropic as a “radical left, woke company.” Just months earlier in March, the Department of Defense labeled Anthropic a “national supply chain risk,” marking the first time a major U.S. technology company had received this public designation, which bars the firm from new federal government contracts. In response, Anthropic launched a lawsuit against the Defense Department and multiple other federal agencies, challenging the designation in court.

    Anthropic has been a key provider of AI tools for high-level U.S. government and military work since 2024, and the company argues the supply chain risk label is nothing more than retaliation from Defense Secretary Pete Hegseth. According to Anthropic’s legal filing, Hegseth retaliated after Amodei rejected the Pentagon’s demand for unfettered access to the company’s full AI model stack, over Amodei’s deep concerns that the technology could be misused for mass domestic surveillance and the development of fully autonomous lethal weapons. While a California federal court ruled largely in Anthropic’s favor in early proceedings, a federal appeals court recently rejected the firm’s request for an emergency temporary stay to block the supply chain risk designation. Even so, Anthropic’s tools remain in active use across all federal agencies that had already deployed the technology prior to the designation.

    Prior to Friday’s meeting, the White House had not issued any positive public remarks about Anthropic, with President Donald Trump himself taking to social media earlier this year to call for an outright ban on the company’s technology across the federal government. In that post, Trump claimed Anthropic was led by “left wing nut jobs” attempting to “strong arm” the U.S. defense establishment, writing, “We don’t need it, we don’t want it, and will not do business with them again!” When reporters questioned Trump about Amodei’s White House visit during a public appearance in Phoenix, Arizona on Friday, the president told reporters he had “no idea” the meeting was taking place.

    In an official statement after the meeting, the White House confirmed the two sides discussed pathways for potential collaboration, as well as shared frameworks and safety protocols to manage risks associated with scaling advanced AI systems like Claude Mythos. “We discussed opportunities for collaboration, as well as shared approaches and protocols to address the challenges associated with scaling this technology,” the White House said, adding that the meeting “explored the balance between advancing innovation and ensuring safety.” Industry analysts say the meeting makes clear that despite the Trump administration’s public hostility toward Anthropic, the company’s advanced AI capabilities — particularly in the cybersecurity space — have become too strategically critical for the U.S. government to cut ties entirely. A representative for Anthropic declined to provide any additional comment on the details of Friday’s meeting when contacted by reporters.

  • Three sentenced for ‘man in bear suit’ insurance scam

    Three sentenced for ‘man in bear suit’ insurance scam

    An audacious insurance fraud plot that relied on a fake bear attack to scam insurers out of more than $140,000 has ended with three Southern California men facing criminal conviction and sentencing. Over a year ago in January 2024, three individuals filed nearly identical expensive damage claims with their insurance providers, all centered on a seemingly bizarre incident at the popular mountain destination Lake Arrowhead.

    To back up their claims, the men submitted viral-ready footage that purported to show a wild bear breaking into and damaging a 2010 Rolls-Royce Ghost. Within the same 24-hour period at the exact same location, two additional claims were filed for separate damage to high-end Mercedes-Benz luxury vehicles, each tied to alleged bear-related destruction.

    When the claims crossed regulators’ desks, the unusual story prompted a review from wildlife experts at the California Department of Fish and Wildlife. Upon close analysis of the submitted video, biologists quickly spotted inconsistencies that ruled out a real wild animal: the “bear” moving through the vehicles had distinctly human proportions and movement patterns, revealing the creature captured on camera was actually an individual inside a full bear costume.

    Following this expert determination, the California Department of Insurance launched a formal investigation branded “Operation Bear Claw”. During execution of a court-issued search warrant at the suspects’ residence, investigators uncovered the full bear costume that had been used to stage the fake attacks, confirming the fraud. In total, the three scammers had wrongfully collected $141,839, equivalent to roughly £105,000, in illegitimate insurance payouts.

    The three defendants — Alfiya Zuckerman, 39, Ruben Tamrazian, 26, and Vahe Muradkhanyan, 32 — all entered no contest pleas to felony insurance fraud charges. During a sentencing hearing held Thursday, a judge handed down a unified punishment: 180 days of jail time followed by two years of supervised probation for each man.

    California Insurance Commissioner Ricardo Lara released a statement following the sentencing, emphasizing the outcome of the unusual case. “What may have looked unbelievable turned out to be exactly that — and now those responsible are being held accountable,” Lara said, highlighting the department’s work to root out insurance fraud that drives up costs for all consumers.

  • What does it take to survive in the Arctic? These rangers have an idea

    What does it take to survive in the Arctic? These rangers have an idea

    Stretching across thousands of kilometers of frozen, unforgiving terrain, the Canadian Arctic is one of the most extreme environments on the planet, where temperatures can plummet to well below -40 degrees Celsius, wind chills can kill a healthy person in minutes, and vast expanses of sea ice and barren tundra offer few landmarks or safe havens. For those who patrol this remote border region year-round, survival is not a matter of luck—it is a set of hard-earned skills, cultural knowledge, and mental discipline passed down through generations. A recent BBC assignment embedded with Canadian military rangers in Canada’s northernmost territory offered a rare opportunity to learn these first-hand lessons about enduring and adapting to the world’s coldest inhabited landscapes.

    Canadian Rangers, a reserve unit of the Canadian Armed Forces made up largely of Indigenous peoples who have called the Arctic home for millennia, have long been the backbone of sovereignty and rescue operations in the far north. Unlike conventional military units trained for large-scale combat, their core mission centers on patrolling remote borders, conducting search and rescue, supporting scientific research, and maintaining a persistent presence in regions inaccessible to most other government forces. To do this work, they rely on a blend of traditional Indigenous knowledge and modern practical skills that allow them to navigate and survive conditions that would defeat even experienced outdoor enthusiasts from more temperate climates.

    During the embedding, rangers shared a range of critical lessons for surviving extreme Arctic conditions, starting with the non-negotiable rule of prioritizing layered, windproof clothing that traps heat without trapping moisture. Many visitors to the Arctic make the fatal mistake of overdressing for cold, leading to sweat that freezes against the skin once activity stops, rapidly dropping core body temperature. Rangers also emphasize the importance of constant situational awareness: thin sea ice can crack without warning, blizzards can roll in in minutes reducing visibility to zero, and even small cuts can become life-threatening when hypothermia already strains the body’s ability to regulate heat. Another key insight is the value of local ecological knowledge: reading wind patterns, animal behavior, and ice formations to predict weather changes and find safe routes across the tundra—a skill that cannot be learned from GPS alone, even with modern satellite technology.

    Beyond practical skills, the rangers stress that mental resilience is just as critical as physical preparation. Isolation, months of total darkness in winter, and the constant pressure of managing risk in a harsh environment can take a significant psychological toll. The close-knit community bonds among rangers, rooted in shared cultural connection to the land, help them cope with these challenges and support one another through the harshest months. For the rangers, surviving the Arctic is not just about enduring it—it is about respecting the land and working with its natural rhythms, rather than fighting against it.

    The insights shared by these rangers come at a time of rapid change in the Arctic, as rising global temperatures melt sea ice, open new shipping routes, and increase human activity in the region. As more researchers, industry workers, and travelers head into the far north, the traditional and practical survival knowledge held by Canadian Rangers has never been more relevant, offering a blueprint for safe, respectful engagement with one of the world’s last great wild landscapes.

  • Officer on horseback chases suspect through New York streets

    Officer on horseback chases suspect through New York streets

    In an unusual incident that unfolded on the busy streets of New York City, a mounted police officer led a dramatic chase through urban thoroughfares to apprehend a suspect accused of purse snatching. The pursuit, which drew attention from onlookers, unfolded as the officer on horseback navigated crowded city blocks to track down the individual implicated in the theft. Following the successful capture, the suspect has been formally lodged with two legal accusations: one count of larceny in connection with the stolen purse, and a second charge for providing false identifying information to responding law enforcement officials. The incident highlights the unique role mounted police units play in urban policing, where their elevated vantage point and maneuverability in crowded areas can help quickly resolve crimes in progress. Local law enforcement has confirmed that the suspect is now in custody, and the case is moving through the city’s legal system, with a preliminary hearing scheduled in the coming weeks.

  • Wildfires used to ‘go to sleep’ at night. Climate change has them burning overtime

    Wildfires used to ‘go to sleep’ at night. Climate change has them burning overtime

    For decades, wildfires across North America followed a predictable rhythm: as temperatures dropped and nighttime humidity rose, flames would die down, giving crews a critical window to contain blazes before they spread further. But a landmark new study published in *Science Advances* confirms what firefighters and researchers have suspected for years: human-caused climate change has thrown that natural cycle off balance, extending wildfire-prone conditions deep into the night and pushing the start of dangerous fire weather earlier each season. The findings paint a stark picture of how rising global temperatures are escalating wildfire risk across the United States and Canada. The study, led by researchers from the Canadian Forest Service and University of Alberta, calculates that the total number of annual hours with weather conditions favorable to wildfire spread across North America has jumped 36% over the past 50 years. In some hard-hit regions, the increase is far more dramatic: parts of southwestern New Mexico and central Arizona now see more than 2,000 additional fire-prone hours each year compared to the mid-1970s, the highest increase recorded in the research. California, a state that has faced repeated catastrophic wildfire seasons in recent years, has gained 550 extra high-risk hours annually. Beyond extending daily burning windows, the research also found the overall wildfire season has grown 44% longer, adding 26 extra days of fire-prone conditions to the calendar over the past half century. Study authors note the shift is driven overwhelmingly by warmer, drier nighttime temperatures paired with slightly increased wind speeds. Unlike past decades when overnight humidity would restore moisture to vegetation and cool temperatures would slow flame spread, modern nights no longer deliver that relief. “Fires normally slow down during the night, or they just stop,” explained study co-author Xianli Wang, a fire scientist with the Canadian Forest Service. “But under extreme fire hazard conditions, fire actually burns through the night or later into the night.” Wang warned that ongoing atmospheric warming means this trend will only grow more severe in coming decades. Overnight-burning blazes are not just a statistical shift — they pose a direct, increased danger to communities and firefighters alike. Recent high-profile catastrophic fires have followed this dangerous new pattern: the 2023 Lahaina wildfire on Maui that killed more than 100 people ignited at 12:22 a.m., while the 2024 Jasper fire in Alberta and 2025 Los Angeles fires all raged uncontrolled through the night. Fires that do not die down overnight gain a critical head start the next day, making them far harder to extinguish, explained John Abatzoglou, a fire scientist at the University of California Merced who was not involved in the study. “Nights aren’t what they used to be — that is, more reliable breaks for wildfire,” Abatzoglou said in an email interview. “Widespread warming and lack of humidity is keeping fires up at night.” Wildland firefighters face unique hazards battling overnight blazes, from navigating dark, rough terrain to encountering nocturnal wildlife displaced by approaching flames. Nicholai Allen, a career wildland firefighter and founder of a home fire prevention company, noted a colleague of his was bitten by a bear fleeing a nighttime fire. “You have to deal with all the same hazards you face in the daytime: snakes, bears, mountain lions,” Allen explained. “But at night, those animals are disoriented and terrified, running straight away from the flames, putting them right in our path.” To reach their conclusions, the research team analyzed hourly atmospheric data — including temperature, humidity, wind, precipitation, and vegetation fuel moisture — from nearly 9,000 large wildfires recorded between 2017 and 2023, using data from weather satellites and ground monitoring stations. They built a statistical model linking weather conditions to fire activity, then applied that model to historical climate data stretching back to 1975 across the U.S. and Canada. The research aligns with longstanding climate science that shows nighttime temperatures are warming faster than daytime temperatures across most of the globe. The root cause is the accumulation of heat-trapping greenhouse gases from fossil fuel burning, which increase nighttime cloud cover that traps heat near the Earth’s surface, acting like a blanket to prevent cooling. Data from the U.S. National Oceanic and Atmospheric Administration confirms that since 1975, average summer overnight low temperatures in the contiguous United States have warmed by 2.6 degrees Fahrenheit (1.4 degrees Celsius), compared to a 2.2 degree Fahrenheit (1.2 degrees Celsius) increase in average daytime high temperatures. This rapid nighttime warming means overnight humidity no longer rebounds to the levels it reached in past decades after a day of hot, dry conditions, explained study lead author Kaiwei Luo, a fire science researcher at the University of Alberta. Drought conditions, which have become more frequent and severe across much of western North America due to climate change, amplify this effect: higher temperatures suck additional moisture out of soil and vegetation, turning trees and underbrush into highly flammable fuel for fires. When vegetation dries out, it can take weeks to regain enough moisture to become less fire-prone, Wang explained. Just as warm summer nights prevent human bodies from cooling off and recovering from heat stress, warmer nights prevent forest ecosystems and vegetation from recovering from daytime heat and dryness. “It’s just an added stress to the plants,” Wang said. “That also increases fuel flammability and makes fire spread more easily.” The trend of lengthened burning windows has already translated to far more area burned across the continent. Between 2016 and 2025, U.S. wildfires burned an average of 11,000 square miles (28,500 square kilometers) — an area roughly the size of Massachusetts — each year, according to the U.S. National Interagency Fire Center. That is 2.6 times the average annual burn area recorded in the 1980s. In Canada, the past decade has seen an average annual burn area 2.8 times higher than the 1980s average, per the Canadian Interagency Forest Fire Centre. Outside experts have called the study a rigorous, important confirmation of climate change’s growing impact on wildfire risk. Jacob Bendix, a fire scientist at Syracuse University who was not part of the research team, called the work “a sobering reminder of climate change’s role in driving increased fire potential across almost all of the fire-prone environments of North America.” This reporting on climate and the environment is supported by funding from multiple private foundations, with The Associated Press retaining full editorial control over all content.
