The Lead: New York's Electric Air Travel Revolution BeginsJoby Aviation's fully electric aircraft has begun test flights in New York City, demonstrating a potential future where urban air travel is transformed by quieter, faster, and more environmentally friendly vertical takeoff and landing technology. The aircraft, which buzzed between JFK airport and Manhattan in recent days, represents a significant step toward making urban air mobility a reality in one of the world's most congested cities.The Technical Breakthrough: Beyond Helicopter DesignWhat makes Joby's aircraft distinctive is its innovative design that deliberately distinguishes itself from traditional helicopters. With six propellers that point upward during vertical takeoff and landing, then tilt forward for horizontal flight, the aircraft combines vertical flexibility with airplane-like efficiency. This multi-propeller configuration not only enables speeds up to 200mph but also provides enhanced safety through redundancy.Eric Allison, chief product officer at Joby Aviation, emphasizes the fundamental differences: "It's an aircraft, but that's about the only similarities. It takes off and lands vertically, like a helicopter, but it has six propellers, which point up when it's taking off and landing, and then they tilt forward to allow forward flight like an aircraft."The Market Potential: Premium Urban Air TravelThe economic implications of Joby's technology are substantial. The aircraft can transport passengers from JFK to midtown Manhattan in approximately 10 minutes—dramatically faster than the more than hour-long journey by car or similar time via public transportation. However, accessibility remains a concern as Joby indicates pricing will be comparable to "premium car service," likely starting around $200 per trip—significantly higher than the $11.75 public transportation fare.This positions the service initially as a luxury option for business travelers and affluent individuals rather than mass transit. The target market appears to be time-sensitive passengers willing to pay a premium for convenience, similar to how helicopter services currently operate but with improved environmental and noise profiles.The Environmental Impact: Quieter Skies, Zero EmissionsOne of Joby's key advantages is its environmental credentials. Unlike conventional helicopters that produce approximately 950lbs of carbon dioxide per hour (compared to 22lbs per hour for an average car), Joby's electric aircraft produces zero emissions during operation. This addresses growing concerns about urban air pollution and climate change.Equally important is the noise reduction. Joby claims its aircraft produces about 45 decibels during flight, compared to helicopters' 100+ decibels. While the company's assertion that the aircraft's "acoustic signature blends into the ambient sounds of everyday city life" may be somewhat optimistic, firsthand accounts confirm it is significantly quieter than traditional helicopters. This could help address the concerns of groups like "Stop the Chop," which has long advocated against helicopter noise in New York.The Regulatory Hurdles: FAA Certification PathDespite the promising demonstrations, significant regulatory challenges remain. Joby Aviation is still in the process of obtaining Federal Aviation Administration (FAA) certification, a rigorous safety evaluation that can take years to complete. The recent New York test flights were conducted under strict limitations, only permitted over water, indicating the cautious approach regulators are taking with this new technology.The certification process involves extensive testing of the aircraft's design, safety systems, and operational procedures. Joby will need to demonstrate that their eVTOL meets the same safety standards as conventional aircraft while addressing unique challenges associated with urban operations, such as integration with existing air traffic control systems and safe emergency procedures in densely populated areas.The Future Outlook: Urban Air Mobility Takes FlightJoby's New York tests represent a critical milestone in the broader urban air mobility movement. If successful, this technology could eventually transform not just New York but other major cities worldwide facing similar transportation challenges. The potential applications extend beyond airport transfers to include emergency medical services, cargo delivery, and eventually routine commuting.However, the path to widespread adoption will depend on multiple factors beyond technical feasibility and regulatory approval. Infrastructure development, including vertiports and charging stations, will require significant investment. Public acceptance will hinge on demonstrating safety and reliability while minimizing noise and visual disruption to urban environments.For now, most New Yorkers will continue their daily commutes via subway and other ground transportation. But as Joby and other eVTOL companies progress toward commercial operations, the skies above cities may soon see a transformation as significant as the one that occurred when automobiles replaced horse-drawn carriages over a century ago.

In a climate where climate denial, vaccine skepticism and "alternative facts" dominate headlines, Helen Pearson shows that the tide of evidence‑based practice is still rising. Drawing on five years of interviews with over 200 experts, she offers concrete steps for citizens, educators and policymakers to push back against the growing rejection of science. The Rise of Anti‑Science Rhetoric in Politics and Public Health Recent statements from high‑profile figures have amplified doubt: Donald Trump labeled climate change a "con job", while U.S. health secretary Robert F. Kennedy Jr. has slashed 25,000 staff positions at science agencies and publicly undermined vaccines. In the UK, only 40% of respondents believe information about science is "generally true". These attacks echo the 1992 backlash against evidence‑based medicine, when a small group of doctors faced accusations of "dangerous innovation". Numbers Showing Declining Trust and Funding Cuts Public trust in scientific institutions fell from 58% in 2018 to 40% in 2025 (Ipsos UK). U.S. federal science staffing reduced by 12% between 2022‑2025, equating to 25,000 jobs lost. Investment in AI‑driven evidence synthesis reached $126 million in 2025, signaling a counter‑trend toward better access to research. Over 70% of English school leaders now report using research to guide decisions, up from 45% in 2010. Evidence‑based anti‑poverty programmes have impacted an estimated 850 million lives worldwide. Why the Erosion of Evidence Matters Across Sectors The decline in trust is not just an abstract concern; it directly affects health outcomes, climate action and economic policy. When citizens reject vaccine data, disease outbreaks become more likely, increasing healthcare costs. Climate denial stalls emissions‑reduction legislation, jeopardizing global temperature targets. In education, ignoring rigorous studies on tutoring and phonics can widen achievement gaps. What Experts Predict for the Future of Evidence‑Based Decision‑Making AI‑powered synthesis tools like Consensus will become mainstream, allowing anyone to query a database of >250 million papers within seconds. Curricula that embed critical‑thinking and "evidence literacy" are expected to be adopted in at least 60% of OECD schools by 2030. Funding bodies are likely to tie grant eligibility to open‑access data sharing, accelerating transparency. Grass‑roots fact‑checking networks will grow, with community‑led platforms verifying claims in real time. Ultimately, Pearson reminds readers that science is a human endeavour—messy, iterative, and sometimes uncertain—but its collective weight still outpaces anecdote. By asking for evidence, checking peer review, and supporting institutions that champion rigorous research, individuals can help tip the balance toward reason.

The Guardian of the Sahara’s 'Sorbonne' In the arid heart of Mauritania, a solitary librarian is battling the dual forces of climate change and economic migration to save the fading legacy of Chinguetti, once known as the 'Sorbonne of the Sahara.' For bookkeeper Muhammad Gholam el-Habot, the responsibility of preserving his family's 1,400 manuscripts is not just a job, but a sacred duty passed down through generations. As the medieval fortress town faces existential threats from the desert, el-Habot’s quiet struggle represents the broader fight to protect human history from the ravages of a changing climate. The Crisis of the Medieval Library The el-Habot family library is one of the few remaining operational strongholds of knowledge in Chinguetti, a ksar (fortress town) that once served as a vital crossroads for trans-Saharan trade. The manuscripts, collected by ancestors who traveled from Egypt to Andalusia, cover a vast array of disciplines including Islamic jurisprudence, mathematics, medicine, and poetry. However, the physical environment of Chinguetti has become increasingly hostile to these fragile texts. The town, which follows traditional Moorish architecture with a mosque at its center, is now largely abandoned as residents seek opportunities in cities like Nouakchott, leaving the preservation of this intellectual heritage to a dwindling number of custodians. Quantifying the Threat to Heritage The threat to Chinguetti’s legacy is not merely anecdotal; it is driven by measurable environmental shifts. Mauritania is 90 percent desert, and climate change is acting as an accelerant for desertification. Researchers note that extreme heat and unpredictable rainfall are damaging texts beyond repair, while the mudbrick structures of the ksar are ill-equipped to handle sudden storms or prolonged heatwaves exceeding 40 degrees Celsius. Furthermore, annual rainfall has decreased by 35 percent since 1970, making it harder for date palms to grow and herders to sustain their livelihoods, which in turn accelerates the migration of the younger generation who are essential for the library's maintenance. The Erosion of the Sahel’s Intellectual Legacy The decline of Chinguetti marks a significant loss for the global community. Historically referred to as Islam’s seventh holiest city and the 'Sorbonne of the Sahara,' the town was a beacon of learning that attracted pilgrims and scholars from across the Muslim world. The loss of these manuscripts represents a gap in human knowledge, as many texts contain unique interpretations of Islamic law and scientific understanding that may no longer exist elsewhere. The challenge is compounded by the lack of capacity among the youth, who view the dusty, labor-intensive work of preservation as unattractive compared to modern economic opportunities. The Future of the Manuscripts The outlook for Chinguetti’s manuscripts is precarious but not entirely hopeless. Recent interventions, such as a $100,000 UNESCO restoration project in 2024 that provided air-conditioning, shelving, and storage boxes to 13 family libraries, offer a temporary reprieve. However, the long-term survival of these texts will likely depend on a hybrid approach: combining local stewardship with international digitization efforts. Without urgent action to secure the physical environment and incentivize the younger generation to return, the sands of the Sahara may eventually reclaim not just the abandoned buildings, but the history they once held.

Queensland’s rapid transition away from coal in 2024 was abruptly halted when the Liberal‑National Party, led by David Crisafulli, seized government and rewrote the state’s energy agenda, sending renewable investors fleeing and leaving the state’s climate goals in jeopardy.The Sudden Policy Reversal That Halted Queensland’s Renewable Surge2024: Labor government pledged to decarbonise the grid by 2035, securing 3,202 megawatts of solar, wind and storage projects.October 2024: LNP wins election, repeals renewable targets and announces coal plants will run until at least 2046.Planning minister Jarrod Bleijie begins “calling‑in” approved projects, demanding local backing before proceeding.Numbers That Show the Collapse of Renewable InvestmentFinancially committed projects fell from 14 projects (3,202 MW) in 2024 to only 2 projects (510 MW) in 2025.Nationally, renewable closures were milder: 8,290 MW reached financial close in 2024 versus 6,529 MW in 2025.South Australia saw a surge, jumping from 210 MW (2024) to 2,118 MW (2025).Queensland’s backlog: over 100 projects awaiting federal environmental assessment; 75% of Queensland‑based applications remain pending.Maintenance fund for coal plants: $1.6 bn allocated, diverting resources from new clean‑energy projects.Why Queensland’s Energy Backslide Threatens Its Climate and Economic FutureThe state accounts for just under a third of Australia’s total emissions. Although official figures show a 34% drop since 2005, emissions from transport, energy and mining have risen when land‑use changes are excluded. The new roadmap is projected to achieve only a 50% cut by 2035, far short of the 75% target set by the previous Labor government.Industry leaders warn that the policy volatility is driving capital to states with bipartisan support for renewables, eroding jobs, skills development and future tax revenue for Queensland. Investor sentiment is clear: “Capital will go where it’s welcome,” says Francesca Muskovic of the Investor Group on Climate Change.What’s Next for Queensland’s Energy Landscape?Analysts suggest three possible trajectories:Policy Stabilisation: If the LNP adopts a clear, long‑term renewable framework, investment could gradually return, leveraging the state’s abundant solar and wind resources.Continued Coal Extension: Maintaining the 2046 coal‑plant deadline risks further isolation from national and global clean‑energy financing, potentially locking the state into higher‑cost, carbon‑intensive generation.Federal Intervention: Accelerated federal approvals and targeted funding (e.g., the $43.8 m for fast‑track assessments) could mitigate bottlenecks, but only if state policies align with national climate commitments.For Queensland to remain a competitive player in the emerging low‑carbon economy, it must reconcile its short‑term coal interests with a credible, stable pathway to renewable energy.

Lead: Borders as a Perpetual Policy DilemmaFrom the first 177km stone wall in ancient Mesopotamia to today’s massive fence networks, governments repeatedly invest in hard borders despite mounting evidence of their limited effectiveness. The piece argues that walls are more symbolic than practical, imposing huge financial and human costs while failing to curb migration.Historical and Contemporary Wall-Building: From Sumer to the EUThe article traces the evolution of border fortifications:177km Sumerian wall – the world’s earliest known barrier, now buried under Iraqi desert.Hadrian’s Wall and the Berlin Wall – iconic structures that were eventually abandoned or toppled.Post‑Cold‑War surge: 12 walls in the early 1990s grew to 74 walls by the 2020s.EU fence expansion: from 315km (2014) to 2,048km (2022).Regional examples: West Bank barrier (>700km), Morocco’s Western Sahara Wall (2,700km), India‑Bangladesh fence (3,000km).Data Analysis: Financial and Human Costs of Modern BarriersTrump’s US‑Mexico wall – estimated at $20 million per mile.US‑Mexico border drownings rose 3,200% between 2020‑2023.UK migration deaths: 257 people between 2018‑2025.EU fence growth added 1,733km of barriers in eight years.Impact Analysis: Why Stronger Walls Fail to Deter MigrationHard borders do not stop people fleeing war, climate crises, or economic hardship; they merely push migrants to riskier routes—tunnels under the US wall, deadly sea crossings, or dangerous desert treks. The article notes that higher barriers can even encourage longer stays, as migrants who survive perilous journeys are more likely to settle permanently. Politically, walls serve as powerful symbols of sovereignty, appealing to voters even when they contradict pragmatic security outcomes.Future Outlook: Will Nations Keep Building Walls?Given the historical pattern and the continued political allure of visible security measures, the article predicts that more walls will be proposed, especially in regions facing migration pressures. However, lasting solutions will require addressing root causes—conflict, climate change, and economic disparity—rather than expanding physical barriers.

The Global Citizen BirdShort-tailed shearwaters, known as yowli in the Wudjari Noongar language, are connecting Indigenous communities across the globe in an unprecedented conservation effort. These remarkable birds travel annually between the southern coast of Australia and Alaska, covering approximately 15,000km with newly fledged chicks in tow. Once so abundant they would darken the skies during Djilba season (August-September) in Australia and Arctic summer in Alaska, these birds are now facing unprecedented challenges that have prompted First Nations peoples to join forces across continents.Cultural Significance Across OceansFor the Wudjari Noongar people of Western Australia, the shearwaters are deeply woven into cultural identity and seasonal understanding. In their language, these birds are called yowli, and their arrival marks significant times in the calendar. Similarly, the Yup'ik people of Alaska have long recognized the importance of these birds' arrival, which coincides with the melting ice and teeming marine life in the Arctic summer.Jennell Reynolds, healthy country program coordinator and senior ranger with Esperance Tjaltjraak Native Title Aboriginal Corporation, shares: "It's so graceful seeing them skip across the water when they're feeding and diving. They are such inquisitive birds when they come into the land." This cultural connection forms the foundation of the cross-continental partnership.The Environmental Crisis UnfoldingBoth Indigenous communities have observed disturbing changes in the shearwaters' behavior and health. Birds are washing up on beaches emaciated, their bellies filled with microplastics instead of food. Others are appearing in locations far from their traditional migration routes, suggesting desperate searches for food in changing oceans.More than 30 million shearwaters return to breeding colonies off Australia's southern coastline each year, with significant numbers also returning to Western Australia's southern coast. The alarming decline in their health and numbers has prompted urgent action from those who have lived alongside them for generations.Building Cross-Continental PartnershipsThe collaboration between Tjaltjraak rangers from Australia and their Eyak, Iñupiaq, Yup'ik and Alutiiq counterparts in Alaska represents a powerful fusion of traditional knowledge and scientific methodology. The partnership was facilitated by David Guilfoyle, a coordinator with the Tjaltjraak rangers who has extensive experience living and working in Alaska."It was one of those things where you know that you've got this connection through this one bird," Reynolds explains. "It's a special moment because we are all on the same page in relation to taking care of country. We both have a kinship with the animals and wildlife and we're making sure that we have that same responsibility for looking after them."Blending Traditional Knowledge with ScienceThe global research project uniquely combines ecological monitoring, scientific analysis, and ancestral knowledge systems. Rangers from both regions are working together to track the birds' migration patterns, health conditions, and changing behaviors.Traditional ecological knowledge offers insights into long-term changes that scientific data might miss, while modern technology provides precise tracking capabilities that complement ancestral observations. This dual approach is proving essential for understanding the complex challenges facing the shearwaters in our rapidly changing environment.A Model for Future ConservationThis Indigenous-led initiative represents a new paradigm in conservation efforts—one that respects and integrates traditional knowledge systems with scientific approaches. As climate change and pollution continue to impact global ecosystems, such collaborations may offer our best hope for understanding and addressing environmental challenges.The shearwaters, in their remarkable journey across the Pacific, have become more than just研究对象—they have become symbols of the interconnectedness of all life and the importance of cross-cultural cooperation in preserving our shared natural heritage.

The Lead: Emergency Ban OverturnedNova Scotia's controversial ban on entering "the woods" during last summer's wildfire emergency has been struck down by the province's supreme court. Justice Jamie Campbell ruled that the vague definition of what constitutes "woods" violated Canadians' constitutional mobility rights, creating confusion for residents while exempting industry groups from the restrictions.The Event Details: Vague Definitions and Legal ChallengesThe emergency ban, implemented as wildfires ravaged the province, prohibited residents from entering "the woods" with penalties reaching up to C$25,000. The definition proved problematic, encompassing rock barrens, scrubland, marshes, and even areas where trees had previously existed but were no longer present. The ban allowed travel through wooded areas as long as it wasn't "any great distance," creating confusion for residents trying to comply.Army veteran Jeffrey Evely deliberately challenged the ban after being fined C$28,872.50 for hiking in Cape Breton. With support from the Justice Centre for Constitutional Freedoms (JCCF), a libertarian-leaning legal organization, Evely took his case to court where he ultimately prevailed.The Data Analysis: Financial and Legal ImplicationsThe case carries significant financial implications beyond the initial fine. The provincial government faced potential liability for the wrongful enforcement of the ban, while also having to consider alternative approaches to wildfire prevention that wouldn't infringe on constitutional rights. The JCCF, which has a history of challenging government overreach, positioned this case as part of a broader movement to protect individual liberties during emergencies.The court's decision emphasized that while governments have the authority to implement emergency measures, they must balance these against protected rights like mobility, which has previously been described as "the heart of what it means to be a free person" in Canadian jurisprudence.The Impact Analysis: Shaping Emergency Powers and Civil LibertiesThis ruling sets a significant precedent for how emergency powers can be implemented in Canada during crises. The court acknowledged the urgency of the wildfire situation but warned that if individual rights aren't protected during emergencies, "they can be eroded in a way that eventually affects everyone." The decision also highlighted inconsistencies in how the ban was applied, with industry groups like forest operators, utilities, and telecom companies receiving permits to continue accessing wooded areas while ordinary citizens faced severe penalties.The case resonates beyond Nova Scotia, connecting to historical tensions between state power and individual rights that date back to the Magna Carta and the Charter of the Forest from 1271, which granted common people rights to access forests.The Prediction: Future of Emergency Measures and Civil LibertiesLooking ahead, this decision is likely to influence how Canadian provinces craft emergency measures during future crises. Governments will need to develop clearer definitions and more balanced approaches that protect public safety while respecting constitutional rights. The ruling may also embolden similar challenges to emergency measures that are perceived as overly broad or inconsistently applied. As climate change increases the frequency and intensity of wildfires and other natural disasters, finding the right balance between emergency powers and civil liberties will become an increasingly important challenge for policymakers and courts across Canada.

On a bright spring morning in Dartmoor, eight‑year‑old Orla and her family experienced a rare wildlife moment when a black adder emerged from the brambles, offering a vivid reminder of the island's hidden biodiversity.Unexpected Visitor: A Black Adder on a Spring WalkThe family had strayed off the main path to admire bluebells when Orla spotted a large, black snake with faint zigzag markings. Following her mother’s calm instructions to back away slowly, the adder lowered its head and slithered away under a rock, leaving the children both startled and fascinated.Adder Statistics: Size, Habitat and Venomous StatusSpecies: Vipera berus (common adder), with the black morph being a rare colour phase.Typical length: about 0.5 m for the observed individual; adults can reach up to 0.8 m.Habitat: heathland, moorland and open grassland across the UK, favouring sunny, sheltered spots.Venom: the only venomous snake native to the UK, though bites are rarely fatal.Population trend: estimated 100,000–150,000 individuals, with numbers stable but locally declining due to habitat loss.Why This Sighting Matters for UK BiodiversityAdder encounters are infrequent because the reptiles are shy and tend to avoid human activity. Public sightings like Orla’s serve several purposes:Raise awareness of the species’ ecological role in controlling rodent populations.Encourage responsible behaviour in natural areas, such as staying calm and giving wildlife space.Support conservation messaging that protects heathland habitats essential for the adder’s survival.Moreover, the story aligns with the Guardian’s Young Country Diary initiative, which invites young voices to share personal nature experiences, fostering a new generation of conservation advocates.Looking Ahead: Adder Conservation in a Changing ClimateClimate change may alter the distribution of suitable adder habitats, potentially pushing populations northward or into higher elevations. Conservation groups are therefore focusing on:Maintaining and restoring heathland and moorland ecosystems.Monitoring population health through citizen‑science reporting.Educating the public on safe coexistence with venomous wildlife.Continued engagement, especially from young observers like Orla, will be crucial in ensuring that the black adder remains a thriving, though elusive, part of the UK’s natural heritage.

The LeadThe oil crisis triggered by the Iran war has fundamentally and permanently changed the fossil fuel industry, turning countries away from fossil fuels to secure energy supplies, according to the International Energy Agency (IEA) chief. Fatih Birol, executive director of the IEA, warns that the damage is irreversible and will have permanent consequences for global energy markets for years to come.The Permanent Energy ShiftSpeaking exclusively to the Guardian, Birol emphasized that the US-Israel war on Iran has caused countries to lose trust in fossil fuels and reduce demand for them. "Their perception of risk and reliability will change. Governments will review their energy strategies. There will be a significant boost to renewables and nuclear power and a further shift towards a more electrified future," he said. "And this will cut into the main markets for oil."Birol stressed that there is no going back from this crisis: "The vase is broken, the damage is done – it will be very difficult to put the pieces back together. This will have permanent consequences for the global energy markets for years to come."The UK North Sea DilemmaWhile focused on the global picture, Birol also addressed the UK's potential plans for North Sea expansion. The oil industry and its allies have called for increased drilling, including giving the go-ahead to the Jackdaw and Rosebank fields. However, Birol cautioned that these fields would not significantly impact the UK's energy security or prices."They won't provide any significant quantities of oil and gas for many years to come," Birol said. "They will not lower the bills, the UK will remain a significant importer and price taker on international markets. I am not even talking about the climate change effects – just from a business point of view, making a major investment in exploration might not make business sense."Birol did support tiebacks—extending existing oilfields—as a different matter that should proceed.The Renewable Energy OpportunityThe vastly changed energy outlook presents expanded opportunities for renewable energy, according to Birol. He highlighted that continuing high fossil-fuel prices could tempt developing countries to turn to coal, but solar is now competitive with coal on cost and growing faster."Renewables offer a no-regrets alternative and nuclear power is also likely to be increased," Birol said. "Building renewables was an option 'I never heard that anybody ever regretted,' he said. 'I don't see any downsides for renewable energy.'"The Global Energy OutlookBirol characterized this crisis as "bigger than all the biggest crises combined, and therefore huge." He expressed surprise that "the world was so blind-sided, that the global economy can be held hostage to a 50km strait."Despite the challenges, Birol sees a path forward: "This crisis will accelerate the energy transition. The question is not whether we will transition away from fossil fuels, but how fast and how well we manage this transition."More than 50 governments, including the UK, the EU, big oil producers and scores of developing countries will meet in Colombia for the world's first international conference on the transition away from fossil fuels, where the global response to the oil crisis and the push for renewable energy will be discussed.
