The Repatriation Effort A plane carrying 300 Ghanaian nationals evacuated from South Africa due to anti-immigration protests has landed in Accra. The group, which included women and children, arrived at the airport in Ghana’s capital on Wednesday. Authorities described their evacuation as a voluntary repatriation process for Ghanaian citizens who no longer feel safe in South Africa amid rising xenophobia that has left migrants facing harassment, job losses and violence. The Exodus from South Africa South Africa has worked with Ghanaian authorities on a list of approximately 800 people who had indicated they want to leave, as a wave of anti-immigration protests has seen campaigners demanding tighter controls on “undocumented migrants,” and accusing foreigners of contributing to crime and unemployment. “Wherever Ghanaians are, we will make sure you are protected,” Foreign Minister Samuel Okudzeto Ablakwa said as he greeted the group at the airport. The Challenges Faced by Migrants South Africa’s Border Management Authority said about 90 percent of Wednesday’s travellers were undocumented, with “most” having overstayed a visa by more than 30 days and “some” by a year or more. Ghana’s high commissioner to South Africa, Benjamin Quashie, however, has criticised South African authorities for backlogs in immigration processing for those seeking to renew their permits. The Impact of Xenophobia The anti-immigrant protests have been accompanied by instances of violence against migrants from other sub-Saharan African countries. One Ghanaian said repeated harassment had driven his decision to leave. “I’m happy that I’m going to my country … it’s not easy to be in someone else’s country and be disturbed all the time,” he told the Reuters news agency. The Future of Ghana-South Africa Relations Quashie said the departures were part of efforts to ease tensions while preserving strong diplomatic ties between the two countries. “The demonstrators have said they want us to work together. We must ensure that those who are undocumented are returned home and that institutions are allowed to function,” the high commissioner said, dismissing speculation of a diplomatic rift with South Africa.

Lead: Climate Crisis Amplifies Antibiotic Resistance ThreatThe latest Lancet Planetary Health study shows that rising temperatures and shifting precipitation patterns have accelerated the global spread of antibiotic‑resistant salmonella, adding urgency to both climate‑mitigation and antimicrobial‑stewardship efforts.The Study Reveals Climate‑Driven Surge in Salmonella Resistance GenesResearchers from the UK, France, Australia, Switzerland and China analysed the genomes of more than 480,000 salmonella samples collected in 139 countries between 1940 and 2023. By correlating resistance‑gene abundance with historical temperature and rainfall data, they identified a non‑linear amplification of antimicrobial‑resistance (AMR) genes linked to climate variables.Quantifying a 10% Global Rise in Resistance Genes (1940‑2023)10% increase in salmonella antibiotic‑resistance genes worldwide over the study period.82% of the examined countries showed rising resistance gene levels.Largest climate‑associated spikes observed in the Middle East & North Africa, followed by South Asia and Sub‑Saharan Africa.Resistance trends varied with both temperature and rainfall, indicating complex environmental drivers.Implications for Global Health and One‑Health StrategiesAntibiotic resistance already kills over 1 million people annually. The study underscores that climate change compounds this crisis by destabilising microbial ecosystems across human, animal and environmental reservoirs, reinforcing calls for integrated One Health surveillance and stricter antibiotic use policies.Future Outlook: Integrating Climate Policy with Antimicrobial StewardshipThe authors advocate urgent alignment of climate‑mitigation actions—particularly those under the Paris Agreement—with enhanced antimicrobial‑stewardship programmes. They argue that adhering to low‑emission scenarios could curb the further spread of AMR genes and reduce the future burden of resistant infections.

The Disappearance of Indonesia's 'Eternity Glaciers' An expedition to document the end days of the last tropical glaciers in Oceania has revealed sombre footage of “planetary destruction on fast-forward”. The State of Puncak Jaya's Glaciers The once-mighty ice sheets on Puncak Jaya, a mountain surrounded by dense rainforests in West Papua, Indonesia, have survived beyond projections they would disappear by 2026 but have shrunk to a fraction of their original size. The most significant of the two remaining glaciers, which are known locally as “eternal snow” and referred to in English as the “eternity glaciers”, has lost 95% of its area since 2002, the expedition found. The Data Behind the Disappearance Papua’s tropical glaciers lost 97% of their ice mass between 1980 and 2024, Indonesian researchers found in a study published last month. Four of its six glaciers have completely disappeared, and they project the final two will be gone by the end of the decade. 97% of ice mass lost between 1980 and 2024 4 out of 6 glaciers have completely disappeared The remaining 2 glaciers are expected to disappear by the end of the decade The Impact of Climate Change Carbon pollution and the destruction of nature has heated the planet by about 1.4C since preindustrial times, making it less hospitable to human life. Glaciers are projected to lose a quarter of their global mass by 2100, even in a best-case scenario for cutting emissions, with devastating consequences for drinking water and food security. The Future Outlook “The ice will be gone: it’s not a question of if, it’s a question of when,” said Klaus Thymann, a Danish explorer and the founder of Project Pressure, an environmental charity. “And ‘when’ is coming very, very soon.”

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.

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.

Investigation and Implications An investigation into the incident is likely to be conducted to determine the cause of the collision and to assess whether any safety protocols were breached. Air Safety Concerns This incident raises concerns about air safety, particularly in regions where paragliding and other forms of recreational aviation are popular. Future Precautions The incident may lead to a review of safety measures and regulations for paragliding and other aerial sports to prevent similar incidents in the future.

The Blue Moon Phenomenon This week’s full moon is a blue moon. The term does not describe the colour of the moon, but instead arises from the way we define our calendar in reference to the stars rather than the moon. Lunar Cycles and Calendar Definitions The moon takes almost a month to circle our planet. The exact time is 29.5 days but if we were to define our calendar as 12 lunar months, the year would fall short by around 11 days. Thus, the calendar would fall out of step with the seasons. The Astronomical Implications By defining our year by how long it takes for the stars to return to their same positions in the sky, we must accept that some years will have 13 full moons instead of 12. The extra full moon is the blue moon, defined as the second full moon in a calendar month. Multiple Definitions of a Blue Moon Having had one full moon already on 1 May, the second one on 31 May this week is the blue one. There is, however, another way to define a blue moon. There is a stricter astronomical way to define a blue moon, known as the seasonal method, but by this reckoning the full moon this week is not blue. Instead, we would have to wait for the full moon on 20 May 2027.

Israeli air strikes across southern Lebanon on May 24, 2026 killed at least six civilians and triggered a fresh wave of 16 evacuation orders issued by the Israeli army, intensifying displacement pressures on local communities.Escalating Israeli Air Strikes Target Southern Lebanese TownsStrikes hit al‑Namiriya, al‑Duweir, Abba, Jebchit, Arab Salim and Bazouriyeh, killing motorcyclists, a paramedic and other civilians. Rescue teams later recovered three bodies in Srifa after a house was hit by warplanes. Hezbollah responded with drone attacks on Israeli positions in Biyyada and a rocket barrage on Rashaf.Casualty Toll and Evacuation Orders: The Numbers Behind the ViolenceAt least six civilians killed in the latest wave of attacks.16 evacuation orders issued for southern Lebanon.Since early March, the Lebanese Health Ministry reports 3,151 people killed and 9,571 wounded by Israeli strikes.Regional Repercussions: Civilian Displacement and Hezbollah’s ResponseThe intensified bombardment forces residents to choose between staying near their homes or seeking long‑term displacement. Hezbollah’s secretary‑general Naim Qassem condemned Lebanese government actions and vowed that recent US sanctions on Hezbollah affiliates would only strengthen their resolve. The violence unfolds against the backdrop of tense US‑Iran peace talks, raising concerns of a broader regional escalation.Looking Ahead: Potential Trajectory of the Lebanon‑Israel ConflictAnalysts warn that continued Israeli expansion of air operations could further destabilize southern Lebanon, prompting more civilian evacuations and potentially drawing Hezbollah into a larger exchange of fire. International attention on the humanitarian impact may increase pressure for diplomatic interventions, but the interplay of US‑Iran negotiations and on‑ground hostilities suggests a volatile outlook for the coming weeks.

The Global Significance of the Fitzroy RiverThe Martuwarra Fitzroy River, which flows 700km through the Kimberley to King Sound, is considered the last stronghold for sawfish globally and is home to four of the world's five species. This untamed river ecosystem supports largetooth, dwarf, green and narrow sawfish, all protected under national environment laws. The river, its estuary and near-shore marine environment provide a critical habitat that represents what a relatively untouched sawfish population looks like on a global scale.The Water Extraction PlanA Western Australian government proposal aims to increase groundwater allocation from about 32GL to 75.7GL in the Fitzroy River catchment. While the draft water plan, now out for consultation, has proposed no additional surface water allocations and no dams on the river, environmental groups are particularly concerned about the increased groundwater extraction. The underground water stores feed several large pools and wetlands that act as crucial refuges for sawfish and other species during long dry periods.The Ecological ImpactEndangered largetooth sawfish, the largest and most imperilled species, are born at the river's mouth and spend several years inhabiting the river, its tributaries and deep aquifer-fed pools before heading out to sea. Adults can reach up to seven metres in size. Conservationists warn that sawfish won't survive without these refuge pools, which also provide life support for barramundi, a whole range of other fish, freshwater prawns and big trees and vegetation that sustain birds, possums, bats and insects.The Indigenous PerspectiveDr Anne Poelina, executive chair of the Martuwarra Fitzroy River Council, an alliance of elders and young leaders from traditional owners of the catchment, emphasized that water is precious and a life force. She stated that the lived experience of Aboriginal people on country is that the river is already stressed, and continued decline will affect people's lives and livelihoods as well as the environment, including access to clean drinking water and the rising cost of living. Poelina called for more time to gather information before any additional licences are granted.The Scientific ConcernDr Leonardo Guida from the Australian Marine Conservation Society described sawfish as "probably one of the most unique looking animals on the planet." Martin Pritchard from Environs Kimberley noted that the underground water stores that feed refuge pools are "absolutely critical in a landscape that's so hot and dry." Dr Ryan Vogwill, a hydrogeologist, explained that groundwater plays an "incredibly important" role supporting the high biodiversity and cultural values of the river ecosystem during dry periods when surface water isn't flowing.Future OutlookThe WA government's draft water plan requires applicants seeking a licence to demonstrate "sustainable groundwater use" and "protect water-dependent ecosystems and sites of ecological, cultural and social significance." However, conservationists remain concerned about the potential impacts, especially given the failure of a similar water allocation plan in the Pilbara where groundwater aquifers are in decline. The Fitzroy River has national and Aboriginal heritage list status for its outstanding cultural and natural values, making its protection a matter of significant environmental and cultural importance.
