Breaking AI & Tech News Analyzed

The Rollercoaster Road to European GloryIf following a football club can be a rollercoaster, this season has been the equivalent of the Oblivion ride at Alton Towers for Crystal Palace supporters. The ride offers "physical trauma, psychological breakdown and chaos" – and Palace fans have been through all that and more over the last 12 months, culminating in a place in the European Conference League final.From FA Cup Triumph to European DemotionIt all started when Crystal Palace won the FA Cup for the first time, beating Manchester City 1-0 at Wembley last May. The mixture of elation, euphoria, disbelief and relief lasted for days, weeks, months and still lives on a year later. After securing that long-awaited first major trophy, the realization sank in that there would be a European campaign to enjoy.However, deep down there was a nagging feeling that this somehow was not real, and sure enough, the lightning bolt landed courtesy of Uefa and Evangelos Marinakis. Nottingham Forest's owner suggested Palace had not conformed to the rules regarding multiclub ownership as one of the club's shareholders, John Textor, had a stake in Lyon. Uefa agreed and Palace were removed from the Europa League and jettisoned into the lesser Conference League.Palace fans were devastated, especially as their place in the Europa League was given to Forest. The Palace owner, Steve Parish, launched an appeal, backed by some vociferous protests from Palace fans, led by the Holmesdale Fanatics, which included taking a suitcase of cash to Uefa's headquarters and spawned a new ditty "Fuck Uefa" that would get plenty of airing.Navigating European Competition with a Thin SquadThe pressure showed in their European debut. The first leg of the playoffs against Norwegian club Fredrikstad was an eye opener. Preparations for the match were disrupted by Eberechi Eze's impending departure to Arsenal and in his absence they struggled to overcome a team that defended so deeply they were almost subterranean. This was to become a recurrent theme in the early stages of the competition. Palace won a scrappy tie 1-0 on aggregate. Glamorous it was not.The team enjoyed an unprecedented unbeaten run, which reached 18 games in all competitions with a relatively comfortable 2-0 win over Dynamo Kyiv in Lublin. That run came to an end with a 2-1 defeat at Everton after a very late goal from Jack Grealish. The novelty of playing in Europe, which necessitated a Thursday-Sunday schedule, was a hurdle that a thin squad struggled to cope with.Overcoming Adversity to Reach the FinalBehind the scenes, the clouds were gathering. Oliver Glasner met Parish to inform him of his intention to leave the club at the end of the season, bemoaning the lack of depth. Things were beginning to unpick. For the home tie with AEK Larnaca, a tifo based on TV comedy Dad's Army was unveiled showing the way to Leipzig, the venue for the final. That felt a bit premature, especially after the Cypriot club ground out a gritty 1-0 win.Next stop Dublin, a trip as relaxed and enjoyable as the warm welcome accorded to Palace fans. Their goalless run continued; Palace coasted to a 3-0 lead and expended little energy preserving their clean sheet. Finnish team KuPS were the last opponents in the group stage, and after a stunning early goal from Christantus Uche, it looked as if Palace would wrap up a comfortable victory. Two quickfire goals for the away side left Palace fans wondering if the European dream was going to be railroaded, but a late Justin Devenny equaliser ensured they made the playoffs.Seminal Victories and European ProgressThe next European tie was two months away and, after beating Fulham at Craven Cottage in early December, Palace were fourth in the Premier League. But more turmoil was on its way. The defence of the FA Cup started, and ended with a trip to Macclesfield, a National League North club 117 places beneath them in the league pyramid. To add to this humbling, Glasner made public his plan to leave, club captain Marc Guehí joined Manchester City and leading scorer Jean-Philippe Mateta was a medical away from joining Milan.A new low was reached when an irate Glasner let rip into the club after losing to Sunderland, saying: "We feel that we are being abandoned completely. Selling our club captain one day before the game makes me really upset today." Eight months after winning the FA Cup, the boat wasn't just listing, it was being dashed against the rocks.The return to European action was a welcome distraction. A win over Bosnian side Zrinjski Mostar in the playoffs set up a last-16 tie with Larnaca, who shut them out at Selhurst Park before a double from Ismaila Sarr in the away leg secured victory. Finally, they landed a glamorous tie with a club steeped in European competition. Fiorentina had been to six European finals including two Conference League finals in the last few years.This was proper European football and, sure enough, as soon as they shed their favourites tag, they put in their most convincing performance at Selhurst Park, winning 3-0 at home to put the tie to bed in the first leg. They had begun the competition proper against a Ukrainian team, so facing Shakhtar Donetsk in the semi-final felt like completing the circle. Palace put in another excellent performance. Ismaïla Sarr scored after just 21 seconds – the quickest goal in Conference League history – and the 3-1 win in Krakow made the second leg at Selhurst pretty much a formality.The Significance of Palace's European JourneyCrystal Palace's journey to the Conference League final represents more than just a successful European campaign. It demonstrates the resilience of a club that has consistently punched above its weight in English football. Despite facing significant challenges – including being demoted from the Europa League, losing key players, and dealing with managerial uncertainty – the Eagles have shown remarkable character to reach their first European final.This achievement also highlights the changing landscape of European football, where smaller clubs can make meaningful progress in competitions that were once dominated by established powerhouses. Palace's run has captured the imagination of neutrals and given their passionate fanbase something to celebrate during a season of domestic disappointment.What Comes Next for PalaceAs Crystal Palace prepares for their European final, questions remain about the club's future direction. With manager Oliver Glasner set to depart and key players potentially leaving, the Eagles face the challenge of maintaining their momentum beyond this historic European campaign. The club will need to balance their European ambitions with the realities of Premier League competition while navigating the complexities of squad building and financial fair play.Whatever happens in Leipzig, Crystal Palace's topsy-turvy season has already secured a place in the club's history books. Their journey from FA Cup winners to European finalists, filled with drama, controversy, and ultimately triumph, will be remembered as one of the most remarkable seasons in the club's 116-year history.

The LeadStarbucks Korea has experienced a significant sales decline following a controversial "Tank Day" marketing campaign that referenced a brutal 1980 military crackdown on pro-democracy protesters. The incident has triggered widespread public outrage, government condemnation, and resulted in the dismissal of Starbucks Korea's CEO as Shinsegae Group struggles to contain the damage.The Marketing Misstep That Ignited Public OutrageThe controversy stems from Starbucks Korea's "Tank Day" campaign, launched on the anniversary of the May 18 Gwangju Uprising—a pivotal moment in South Korean history when the military government deployed troops and tanks to suppress pro-democracy demonstrations in 1980. The campaign, which many perceived as trivializing or mocking the historical event that resulted in hundreds of deaths or disappearances, immediately sparked public backlash.Shinsegae Group, whose subsidiary E-Mart operates Starbucks in South Korea, has faced mounting criticism over the insensitive marketing approach. In a news conference on Tuesday, Shinsegae Group chairman Chung Yong-jin made a public apology and urged people not to direct their anger at Starbucks Korea employees and front-line staff."I take it very seriously, the fact that many people felt deep pain and anger because of Starbucks Korea's inappropriate marketing campaign," Chung said. "I will take all responsibility for the incident."Financial Fallout and Corporate ResponseThe marketing controversy has had immediate financial consequences for Starbucks Korea. A Shinsegae official confirmed that sales have fallen sharply since the campaign was launched. "While sales are not our main concern at the moment, we have seen a very significant drop," the official stated.In response to the crisis, Shinsegae took swift action by firing the head of Starbucks Korea last week after apologizing for the campaign. Starbucks Global also issued an apology and announced that an internal investigation had begun. Chung Yong-jin issued his first apology on May 19, acknowledging that the campaign caused "deep pain to the victims and bereaved families of the May 18 Democratization Movement as well as to the public."During the internal review, some employees refused management requests to hand over their smartphones, complicating the investigation. Shinsegae stated they would await the results of a police inquiry and would terminate any employee found to have intended to ridicule the pro-democracy protesters.Political and Cultural RepercussionsThe backlash against Starbucks Korea extends beyond public opinion into the political realm. Government officials, including Interior and Safety Minister Yoon Ho-jung, have condemned the campaign, stating that Starbucks products will no longer be used at government events. Minister Yoon lamented what he described as the chain's "anti-historical behavior."South Korean President Lee Jae Myung went even further, taking to social media platform X to denounce the campaign as displaying "inhumane and disgraceful behaviour by cheap profiteers who deny the values of the South Korean community, basic human rights and democracy." The strong political response has amplified public calls for boycotts of Starbucks across the country.The incident has highlighted the sensitivity around historical events in South Korea, particularly those related to the country's transition to democracy. The May 18 Gwangju Uprising remains a traumatic and significant event in South Korean history, symbolizing the struggle against authoritarian rule.Recovery Path and Future OutlookFor Starbucks Korea, the path to recovery will require more than just executive apologies and personnel changes. The company will need to demonstrate a genuine understanding of South Korean history and cultural sensitivities in its future marketing efforts. This incident serves as a stark reminder of the importance of cultural intelligence in global marketing strategies.The long-term impact on Starbucks' brand reputation in South Korea remains uncertain. While the company has a strong presence in the country, this controversy could lead to lasting consumer distrust if not addressed appropriately. Shinsegae's handling of the aftermath—including their commitment to transparency in the investigation and their expressed willingness to take responsibility—will be crucial in determining whether the brand can recover from this significant setback.As global companies navigate increasingly complex cultural landscapes, the Starbucks Korea case study will likely be referenced as a cautionary tale about the potential consequences of failing to understand local historical contexts and sensitivities.

The Lead Elon Musk and Sam Altman's AI rivalry has reached unprecedented levels as both tech titans prepare for massive IPOs that could reshape the artificial intelligence landscape. The week's developments highlight a high-stakes battle for dominance in what is arguably the most consequential technology of our time. The Legal and Financial Battle On Monday, Musk lost his lawsuit against Altman and OpenAI, with a federal jury in Oakland finding them not liable for Musk's claims that they unjustly enriched themselves and broke a founding contract. The verdict, delivered after less than two hours of deliberation, provides OpenAI with a clear path to pursue going public later this year at about a $1tn valuation. On Wednesday, Musk countered by revealing SpaceX's plans for its $1.75tn initial public offering. The rocket and satellite operations company will go public on the Nasdaq exchange at a valuation of about $1.75tn under the symbol SPCX, likely on 12 June, seeking up to $80bn in investment. Then on Thursday, the Wall Street Journal reported that OpenAI was hurtling towards an initial public offering, perhaps even as soon as Friday, though the company did not file to go public that day. The Financial Stakes SpaceX's investor prospectus revealed significant financial details, showing the company is plowing billions of dollars into its AI subsidiary, xAI. The company had a capital expenditure last year of more than $20bn against $18.7bn in revenue for 2025 and lost over $4.2bn in the first three months of 2026. The prospectus lists OpenAI along with other major AI firms such as Anthropic as key competitors to SpaceX's business. With all three AI businesses potentially going public this year at valuations of hundreds of billions or more than a trillion dollars, this represents one of the most blockbuster periods for public offerings in market history. Industry Transformation The rivalry between Musk and Altman reflects a broader shift in the tech industry as AI becomes the central focus of innovation and investment. Control over artificial intelligence is increasingly concentrated in the hands of a small group of powerful individuals, raising questions about the future direction of the technology and its impact on society. Meanwhile, Google entered the fray with its unveiling of Gemini Spark, a 24/7 personal AI agent designed to proactively manage tasks and help users navigate their digital life. The product represents Google's ambitious attempt to integrate all its services into a cohesive AI-powered experience that could potentially replace traditional smartphone interactions. Google also announced significant changes to Search, shifting from the traditional list of 10 blue links to a chatbot interface that summarizes information for users rather than requiring them to navigate to sources themselves. The Future Outlook As we move toward a future where AI agents potentially replace smartphones as the primary interface for digital interaction, the rivalry between Musk, Altman, and other tech leaders will likely intensify. The coming IPOs of major AI companies could trigger a wave of investment and innovation that accelerates the development of artificial intelligence capabilities. However, the concentration of power in the hands of a few tech leaders also raises important questions about regulation, ethical development, and equitable access to AI technologies. As these companies go public, they will face increased scrutiny from investors and regulators alike. The race to dominate the AI space is not just about financial success—it's about shaping the future of human interaction with technology and determining who will control the most transformative technology of our time.

The Graduation Backlash Against AI OptimismWhen Jacob Pagel graduated from Middle Tennessee State University this spring, predictions about artificial intelligence already had him questioning the value of his degree. Then a music executive started preaching about AI's transformative power during a commencement speech."This industry will change on you in a heartbeat. It has already changed more in the last 10 years than in the 50 years prior … AI is rewriting production as we sit here," said Scott Borchetta, CEO of the record label Big Machine. After a few stray boos from graduates, he doubled down: "Deal with it."The students' jeering grew louder, but Borchetta barreled through: "You can hear me now or you can pay me later … then do something about it. It's a tool. Make it work for you." He continued: "The things you learned in your first year here may already be obsolete."Multiple Universities, Same Student FrustrationBorchetta's speech is one of several at commencement ceremonies this spring that have revealed a disconnect between the executives championing AI and students, eliciting derision in real time even for Google's former CEO. Recent graduates at the University of Central Florida and the University of Arizona booed speakers who compared the advent of AI to the Industrial Revolution and the development of the laptop and smartphone.At the University of Arizona, 20-year-old Arian Chavez, was angry about his school's decision to let ex-Google CEO Eric Schmidt speak, even before he got on stage. Chavez, a junior studying chemical engineering, is part of a group called Students for Socialism, and helped them organize an online petition to remove Schmidt as a commencement speaker."I know what many of you are feeling about that. I can hear you," Schmidt said, amid a chorus of boos. "There is a fear in your generation that the future has already been written, that the machines are coming, that the jobs are evaporating, that the climate is breaking, that politics is fractured, and that you are inheriting a mess that you did not create, and I understand that fear."Public Sentiment: AI's Poor ReceptionThe students at these ceremonies "are a mouthpiece for the population at large", according to Cornell University professor Sarah Kreps, who has studied societies' reactions to new technology. "These tech executives are not reading the room … These kids have spent hundreds of thousands of dollars on a degree that they don't know will serve them well."While they may feel AI's disruptive effects acutely as entry-level job seekers, AI has proved unpopular among the general US public. A national survey conducted for NBC News earlier this year polled 1,000 registered voters and found only 26% view AI positively and 46% view it negatively. AI scored worse than US Immigration and Customs Enforcement (ICE), Donald Trump and Kamala Harris on the same poll, but better than the Democratic party and Iran.Anger against AI is palpable across the country – from communities protesting against datacenters powering the AI boom, to workers disputing their CEOs' claims that AI can, effectively, replace them.The Economic Reality Behind the Student AnxietyPagel and his peers are entering a job market where AI's efficiency is already being used to justify mass layoffs. While it's unclear which jobs may be entirely replaced by AI – and whether AI could eventually create more career pathways than it destroys – recent graduates are feeling betrayed."We've been pushed our entire lives to get our diplomas. Then you pulled the rug out from underneath us, and said: 'Oh, you know those four years you spent learning how to do very specific things, you don't need to do it any more,'" Pagel says. "We can get a computer to do it for two-thirds the price."CEOs' graduation speeches about AI have become a preventable PR disaster, according to Parry Headrick, founder of Crackle PR, a tech public relations agency that has worked with startups. Executives should have acknowledged and reassured students' anxieties, while also advising them to adapt."What in the heck is anybody who is young and in school supposed to do when you have these tech executives beating their chests about the next Industrial Revolution when they can't afford to buy groceries or pay for rent?" Headrick asks. Nearly half of college students said their financial stress made it hard to concentrate on their coursework, according to a 2026 report from Trellis Strategies, a research group focused on postsecondary education.AI's Practical Impact on Education CeremoniesAt Glendale Community College in Arizona, it wasn't a graduation speaker that drew students' ire, but the AI-powered machine reading out their names. Turns out, it missed some.College president Tiffany Hernandez apologized and told graduates towards the end of the ceremony: "Here's what's happening. We're using a new AI system as our reader," she said, as boos roared through the arena. Hernandez paused for a few seconds and let out a few nervous laughs. "That's a lesson learned from us."Aidan Benjamin, who is graduating from Glendale Community College this summer with an associate's degree in accounting, was at the ceremony to support his cousin. He thought she would be walking the stage. She never did, because the AI announcement system never called her name."I was booing because I was like, this sucks. This is such a big moment for students." Benjamin said they both laughed about the malfunction afterwards. "But it just didn't feel good at the end of the day, like, it shouldn't have happened that way," he says.The Future of AI in Education and CareersPagel is considering a career in helping children undergoing medical treatment, or entering politics – perhaps running for office, or working as a liaison for federal agencies. "That sphere depends on human face-to-face interaction. No computer can take that," he says, calling AI-generated campaign ads "the cheap route"."It's up to us as engineering students to use our knowledge for the service of the planet and not billionaires," says Arian Chavez, who wants to work in the environmental regulation of chemical plants.As AI continues to reshape industries and education, the graduation protests may represent an early indicator of a generational shift in how technology is perceived – not as an unqualified good, but as a force that requires careful management to avoid displacing workers and devaluing human expertise.

The Consultation Aims to Rein in Under‑16 Social Media UseBritain’s Online Safety Act is being extended with a new consultation that could impose an Australia‑style ban on users under 16, or force platforms to disable "addictive" features such as infinite scrolling, push notifications and autoplay. The deadline for written submissions is Tuesday night, and ministers have signalled a rapid legislative response.Possible outright ban for under‑16s on major platforms.Alternative: block only services that fail strict safety standards.Targeted curbs on algorithmic feeds and endless‑scroll designs. Bereaved Parents Call for a Nuanced, Not Blanket, ApproachIan Russell, 62, father of Molly Russell (who died after exposure to harmful content on Instagram and Pinterest), urges a "nuanced" strategy. He opposes a blanket ban, warning it would create a "cliff edge" where teens jump to unregulated apps once they turn 16. Russell wants platforms that do not meet safety criteria blocked for under‑16s, while "safe" apps remain accessible.Esther Ghey, 39, mother of the late Brianna Ghey, backs raising the age limit. She argues that social‑media addiction contributed to her daughter’s mental‑health decline and risky behaviour. Ghey also stresses the need for digital‑literacy education alongside any age‑based restrictions. Teen Voices Highlight Complexity and Practical ConcernsFin, a 17‑year‑old sixth‑form student, describes the proposals as "incredibly harsh" for youths who rely on platforms for news and social connection. He suggests tiered restrictions rather than a total ban and points out that schools already depend on smartphones for learning tools like Google Classroom and Microsoft Teams.Focus groups run by the NSPCC with 11‑ to 18‑year‑olds echoed these sentiments, calling for a "layered approach" that lets young people gain gradual exposure while retaining control over content and interactions. Parliamentary Perspective on Regulation and EnforcementChi Onwurah, MP, emphasises that any new rules must be enforceable and backed by clear accountability for tech firms. She warns that without robust monitoring, a simple age limit could be bypassed, undermining the intended protective effect. What Comes Next for UK Online Safety Policy?The government will review the consultation responses and is expected to draft legislation before the end of the year. Stakeholders are urging a balance between protecting children from harmful content and preserving their ability to engage responsibly online. The outcome will shape how the UK aligns with global trends in digital‑age regulation and could set a precedent for future tech‑policy debates.

The 39‑year‑old’s farewell was marked by an emotional ceremony and tributes from French tennis greats, closing a 21‑year saga at the French Open.The Final Match: Monfils vs. Gaston Ends a 21‑Year RunMonfils fell 6‑2, 6‑3, 3‑6, 2‑6, 6‑0. After a strong start, he rallied to level the contest, but a foot injury hampered him in the decisive set, allowing Gaston to seal the win.Numbers that Define a CareerAge: 39Career‑high ranking: No 6ATP titles: 132025 Auckland 250 victory: oldest man to win an ATP titleFrench Open appearances: 21Match score: 6‑2, 6‑3, 3‑6, 2‑6, 6‑0Legacy and Impact on French TennisMonfils’s “show‑man” style turned Roland Garros into a theatre of drama, inspiring a generation of French players. His farewell ceremony, led by tournament director Amélie Mauresmo and French Tennis Federation president Gilles Moretton, featured former compatriots Gilles Simon, Jo‑Wilfried Tsonga and Richard Gasquet, underscoring his deep ties to French tennis.The crowd’s unwavering support, even as the match slipped away, highlighted his lasting popularity. Monfils’s longevity—still competing at a Grand Slam at 39—sets a benchmark for fitness and resilience in the sport.What Lies Ahead for Monfils and French TennisWith retirement imminent, Monfils may transition to coaching, commentary, or ambassadorial roles, leveraging his charisma to promote the sport. His departure opens space for younger French talents, such as Gaston, to step into the spotlight, potentially reshaping France’s future on the clay circuit.

Ian McEwan Warns Pessimism Threatens Climate ActionAt a Hay Festival panel on 26 May 2026, acclaimed novelist Ian McEwan argued that widespread pessimism is "a bigger problem than climate change" and that optimism should be treated as a moral duty to sustain future generations.Panel Highlights Climate Concerns Amid Record HeatMcEwan shared the stage with former NFU president Minette Batters and broadcaster Sandi Toksvig. The discussion unfolded as London hit 34.8°C, breaking a May record set in 1922, underscoring the immediacy of climate impacts.Record‑Breaking May Temperatures QuantifiedLondon temperature: 34.8°C on 25 May 2026.Previous May record: 1922.UK heatwave coincided with the release of McEwan’s new novel What We Can Know, set in a flooded 2119 Britain.How Pessimism Undermines Public and Agricultural ResilienceMcEwan linked pessimism to reduced civic engagement, suggesting that optimism fuels rational action. Batters warned that extreme weather left her farm with only 50% of normal hay and silage yields, and that just 7% of English farmers fully understand Defra’s farming vision.Outlook: Shifting Toward Optimism and Policy ChangeBoth speakers called for concrete steps: McEwan cited renewable electricity surpassing fossil fuels in 2020 as a hopeful milestone, while Batters criticized policy uncertainty, including proposals like a land‑value tax. The panel concluded that fostering optimism—through small personal actions such as installing balcony solar panels—could create a “nudge” toward broader climate solutions.

Heatwaves have grown hotter and stronger as the planet has warmed, making what doctors call a "silent killer" even more dangerous. How worried should we be about heat – and how can we stay safe as the climate changes?The Human Cost of Extreme HeatHot weather kills an estimated half a million people each year. The average annual death toll is greater than that from wars or terrorism, but smaller than that from cars or air pollution.Despite this, heat is rarely listed as the cause of death. That's because extreme temperatures are largely indirect killers. Most heat victims die early from illnesses – such as heart, lung and kidney disease – that are made worse in warm weather.The Physiological Impact of Heat StressHigh heat stresses the human body, sending the heart and kidneys into overdrive as they work to keep the body cool. The added strain – particularly for those with chronic illness – can prove fatal even before heatstroke hits.There are also secondary health effects from high heat. Heatwaves lead to more accidents, dirtier air, bigger wildfires and more frequent power outages, all of which can increase the burden on health systems.The Critical Role of Nighttime TemperaturesWhen days are too hot to function and nights are not cool enough to recover, the body is unable to rest. This compounds the damage done during scorching days.In many European countries, meteorologists describe nights with temperature minimums above 20°C as "tropical", while in Spain, which is more familiar with extreme heat, they call nights above 25°C "equatorial" or "torrid". In recent years, they have informally introduced a new category for night-time temperatures above 30°C: "hellish".Identifying Vulnerable PopulationsPeople who are forced to be outdoors in scorching weather – builders, farmers, rough sleepers etc – are most likely to suffer from heat exhaustion and the heatstroke that can follow.But older people, and particularly those with underlying illnesses, make up the bulk of heat-related deaths. Women are more likely to die from heat-related causes than men. Poorer people – who are less likely to have air conditioning, well-insulated homes or access to green spaces – are also at greater risk.The Humidity FactorSweat is the body's best defence against heat, lowering internal temperatures as it evaporates. But when humidity is high and the air hot and sticky, the body struggles to cool down because sweat clings to the skin. The effect this has on perceived temperatures can be equal to several degrees, enough to spell the difference between life and death.Climate Change and Escalating HeatwavesMore than a century's worth of fossil fuel pollution has clogged the atmosphere, trapping sunlight and heating the whole planet. Average global temperatures have risen by about 1.3°C since preindustrial times – and land temperatures by even more – which has pushed the baseline higher and made punishing extremes far more common.There is also some evidence that the climate crisis is making heatwaves worse by weakening the jet stream. Scientists think this is increasing the occurrence of heat domes, which are areas of high pressure and heat that get stuck over a region for days or even weeks.The Net Effect of Rising TemperaturesCold weather kills far more people than hot weather today, even in warm regions such as sub-Saharan Africa and south Asia. But as temperatures rise, the number of deaths from heat is projected to grow much faster than the number of lives saved from milder cold. When scientists modelled this in 854 European cities, they found a net increase in temperature-related deaths under all emissions scenarios, even accounting for how people adapt.Adapting to a Hotter FutureCutting fossil fuel pollution is the biggest step that can be taken to stop heatwaves from getting even hotter, along with protecting forests and wetlands that suck carbon dioxide out of the atmosphere.Urban planners have called for cities to be redesigned so they have less concrete and fewer cars, and more parks and water. This can negate the urban heat island effect, which makes cities hotter than their rural surroundings.Buildings with air conditioning or passive cooling can bring down death tolls, as can strong healthcare systems and swift emergency warnings.The Air Conditioning DilemmaAir-conditioning units increase planet-heating emissions if the power they consume is generated by burning fossil fuels, as it mostly is today, but their pollution is falling as countries clean up their electricity grids. Some experts cite the scale of the heat-related death toll as a worthy reason to use more air conditioning – particularly for the most vulnerable groups – even if it pushes temperatures higher.This year, the UK's Climate Change Committee (CCC) recommended that air conditioning be installed in all care homes and hospitals within the next 10 years, and in all schools within 25 years.Personal Safety StrategiesThe simplest advice is to stay out of the heat: avoid going outside during the hottest parts of the day, and stay in the shade if you have to. To keep your home cool, close windows during the day and open them after dark, when outdoor temperatures fall below inside temperatures. Cover windows with blinds or curtains to block out direct sunlight.Doctors also recommend drinking water frequently, wearing loose clothing and checking on vulnerable people in your community.
