Costa Rica Court Orders Power Line Changes to Protect Howler Monkeys from Electrocution

Costa Rica's constitutional court has ruled that the state electricity company must implement measu…
The Lead: Costa Rica's Court Ruling for Monkey Protection Costa Rica's constitutional court has ordered the state-owned electricity company and the Ministry of Environment to implement measures to prevent howler monkeys from being electrocuted on uninsulated power lines. The ruling comes after conservation organizations documented a growing problem with monkeys mistaking power lines for trees and vines, resulting in hundreds of electrocutions annually. The Rising Crisis: Development and Electrocution Peque, a small black howler monkey, was found electrocuted with her mother who didn't survive the incident. She was one of more than 100 animals to arrive at International Animal Rescue Costa Rica (IARCR) in 2025 due to electrocution on power lines. Howler monkeys account for up to 90% of these incidents. Francisco Sánchez, a veterinarian at IARCR, has observed a rise in cases over the past decade, attributing it to increased development in the Nosara area, which has become a popular tourist destination and haven for US and European immigrants. "Now, we have new areas [of electrocutions] appearing that we didn't have in the past," he explains. "This is because of the development of houses, restaurants and hotels. We are rescuing from further inside the forest." The Legal Response: Constitutional Court Mandate In January, Costa Rica's constitutional court ruled that the Costa Rican Electricity Institute (ICE) and the Ministry of Environment and Energy (MINAE) had failed to put in place effective measures to reduce and prevent wildlife electrocution. The court gave them six months to implement necessary corrections to the bare wiring in power lines in the Nosara district. The ruling resulted from a campaign called "This Is NOT Pura Vida" by 20 conservation organizations and rescue centers, including IARCR, which called for urgent government action. IARCR subsequently launched the court case that led to this decision. The National Impact: Beyond Nosara The ruling could have major ramifications for wildlife protection nationwide, according to Gavin Bruce, chief executive of International Animal Rescue. "Although this case was built on data from the Nosara area, the problem is nationwide," he states. "We will now monitor the implementation of the ruling and consider how best to scale these protections across the entire country." In Costa Rica, the only country thought to regularly log wildlife electrocution numbers, electric shock is one of the biggest causes of death among wildlife, with 6,262 cases between June 2022 and June 2023. MINAE claims to have already implemented "a broad range of measures aimed at preventing wildlife electrocution incidents" and has "promoted a sustained collaborative process" to develop solutions. The Global Context: A Widespread Wildlife Threat While the impact of power lines on birds has been well-documented, there is a lack of global studies on the effect on mammals, making it difficult to quantify the problem worldwide. Justo Martín Martín, an environmental consultant specializing in the issue for the International Union for Conservation of Nature (IUCN), notes that "there are few systematic studies but there is abundant evidence... that the problem is global." Looking Forward: The Path to Protection The constitutional court ruling represents a significant step toward addressing the electrocution crisis in Costa Rica. Conservation groups hope the decision will force electricity providers nationwide to implement proper insulation and other protective measures for power lines. With Costa Rica being a global leader in biodiversity conservation, this case could set an important precedent for other countries facing similar challenges with wildlife and power infrastructure.

The Death of a Legend: The Major Oak's Final Chapter

The Death of a Legend: The Major Oak's Final Chapter The Major Oak, a 1,000-year-old icon of Sherwood Forest and English folklore, has died, marking the end of an era for one of Europe's most celebrated ancient trees. Located in Nottinghamshire, the tree failed to produce leaves this year, succumbing to the cumulative stress of global heating, particularly the record-breaking heatwave of July 2022. Once a sanctuary for the outlaw Robin Hood and his gang, the tree attracted 350,000 visitors annually. Its passing was marked by an impromptu funeral, with Robin Hood himself arriving in an electric van to pay respects, alongside mourners from around the world. The White Rhinos of the UK: Ancient Oak Statistics England possesses a unique wealth of very large and ancient oaks, described by conservationists as "the white rhinos of the UK." The Major Oak's death underscores the rarity of these biological giants. 114 living ancient oaks with a girth of more than nine metres exist in England. 98 such oaks are found across the rest of Europe, including Scotland and Wales. The Major Oak had a canopy spanning 28 metres and a trunk girth of 11 metres. Conservation Paradox: How Well-Intentioned Care Hurts Ancient Trees The tree's longevity was compromised by a series of well-intentioned but ultimately damaging human interventions. Experts believe that the props and metal chains installed in 1904 to support its branches prevented the tree from naturally "growing down"—a process where ancient oaks shed limbs and retreat into their trunks to conserve water. 1904: Props and metal chains installed to support branches. 1960s: Hollow parts of the tree filled with concrete. Soil Compaction: Weakened by visitors and wartime military use. Chloe Ryder, RSPB Sherwood Forest estates operations manager, noted that the props likely impacted the tree's ability to sustain itself, creating a dependency that ultimately hastened its decline. A Warning for the Future of Ancient Woodlands The Major Oak's death serves as a stark reminder that ancient ecosystems are increasingly vulnerable to climate change. As global heating leads to more frequent and intense droughts, the resilience of trees that have survived for centuries is being tested beyond their limits. The legacy of the Major Oak now lies not just in its history, but in the lessons it teaches about the delicate balance required to preserve our natural heritage.

David Hockney's Yorkshire Renaissance: From Swimming Pools to Pastoral Landscapes

David Hockney's return to Yorkshire marked a significant artistic reawakening, transforming from hi…
The Lead David Hockney's return to Yorkshire triggered a profound artistic renaissance, marking a significant evolution in his celebrated career. The renowned British artist transitioned from his iconic swimming pool portraits to capturing the pastoral beauty of his homeland, embracing both traditional techniques and digital innovation. The Yorkshire Artistic Revolution Hockney's later work represents a deliberate departure from his earlier fame, focusing instead on the landscapes of Yorkshire where he found new inspiration. His paintings of emerald hedgerows, purple trees, and seasonal changes demonstrate a deep engagement with the natural world. This shift wasn't merely geographical but represented a philosophical evolution in his artistic approach, moving from urban sophistication to rural simplicity while maintaining his distinctive visual language. The Digital Renaissance: iPad Art During Pandemic When the pandemic began, Hockney was living in Normandy where he continued his exploration of new technologies. Already adept with an iPad, he began creating daily digital paintings of his garden and sharing them via email. These works depicting spring in Normandy—trees rustled by breeze, rain spattering ponds—became more than just artistic exercises; they offered hope and happiness during a global crisis. His "Ping! Another email, another sunrise in vivid electric yellow" became a daily ritual for many, bringing art directly to people's homes during lockdown. The Evolution of an Artistic Vision Hockney's career demonstrates remarkable consistency despite apparent transformations. From his early days in California and London to his later Yorkshire period, he maintained a fascination with perspective, light, and the representation of space. His opera set designs for Stravinsky's "Rake's Progress" revealed his enduring interest in art history and visual storytelling, themes that continued in his landscape work. The artist himself acknowledged this continuity, explaining that his Yorkshire paintings were not a departure but an extension of his lifelong exploration of how we see and represent the world. The Impact of Personal Transformation Hockney's personal evolution mirrored his artistic development. His move from the city to the countryside, his embrace of natural aging (letting his hair become its natural gray), and his adaptation to deafness all influenced his work. These changes weren't losses but transformations that enriched his art. The "glam-age" Hockney of the 1970s gave way to a more contemplative figure whose work engaged with deeper questions about nature, time, and perception, demonstrating how personal growth can fuel artistic innovation. The Future of Hockney's Legacy As Hockney continues to create, his legacy expands beyond his individual works to influence how art is created and shared in the digital age. His embrace of technology while maintaining traditional artistic values bridges past and future, showing that innovation need not reject heritage. His daily digital paintings during the pandemic demonstrated how art can serve as both personal expression and communal connection, offering a model for artists in an increasingly digital world. As he continues to explore new mediums and subjects, Hockney's work remains vital, proving that great art evolves while staying true to its essential vision.

A Culinary Journey Through Frida Kahlo's Mexico City

The author takes readers on a journey through Frida Kahlo's Mexico City, experiencing a culinary tr…
The Culinary Connection Today you're going to eat art, says Federico Valdez, a chef at the School of Mexican Cuisine with the word Queso (Cheese) tattooed on his forearm. Today, you're going to eat history. In a sun-filled dining room lined with Mexican flowers, books and artefacts, unfolds a three-course feast inspired by Frida Kahlo, her life, her art and her loves, including her first lesbian affair. The starter, inspired by her childhood fascination with revolution, is a lightly spiced Mexican take on pirozhki, the Russian favourite. The main dish – served with pulque, an agave-derived drink Kahlo loved – taps into her rebellious spirit. It's called Frida Against the World, a giant stuffed chilli that sits amid a nutty, beany sauce similar to the one eaten at Kahlo's wedding to Diego Rivera, then the most famous artist in the world, now much more in her shadow. When she found Rivera in bed with her sister, she said: 'I'm going to get all my furniture and leave. I hate you' "I wanted this to be hot and horny," says Valdez, explaining that halved figs were added to reference Kahlo's sexuality. "Her first love, with a female teacher, happened at a time when Mexico wasn't so open. I wanted to get in all that spicy gossip. I'm not a big fan of playing it safe." The Exhibition Preview I'm in Mexico City with a Tate delegation just as the huge jacaranda trees are blooming purple and violet across its parks and boulevards – to follow in Kahlo's footsteps ahead of Frida: The Making of an Icon, a show of more than 30 of her works at Tate Modern in London that seems destined to be a summer blockbuster, adding yet more fuel to Fridamania. One work, Self Portrait With Thorn Necklace and Hummingbird, was painted in 1940 after her painful divorce from Rivera. A spider monkey, similar to the one he gave her as a present, is pulling on her thorn necklace, drawing blood. The two soon remarried, Kahlo inscribing the clocks in their house with the years of their separation and reunion. "The exhibition is like a movie," says Tobias Ostrander, its curator. "Frida is the star but it's also about her life, her people, her impact." Charting Kahlo's rise from unknown painter to global phenomenon, the show will also examine merch (expect a Kahlo Barbie) and gauge her influence on later artists. On display, too, will be many of the artist's treasured possessions, including her brilliantly patterned tehuana dresses. Graciela Iturbide's ghostly photographs of her crutches, customised medical corsets and prosthetic leg will also feature. These were taken 50 years after Kahlo's death, when all her belongings were finally freed from the bathroom in which Rivera had ordered them to be locked away. The Casa Azul Experience This took place at Casa Azul, the house in Coyoacán (The Place of the Coyote Owners) where Kahlo was born and spent most of her 47 years. It's now a beautiful, beguiling museum with smooth exterior walls painted a gorgeous blue. These border shiny red concrete paths that thread through fountains and lush gardens bursting with palm, yucca, cactus and bougainvillaea. "We don't know exactly where the blue came from," says Perla Labarthe Álvarez, the museum director. "But in her diary, Frida expressed what the colour meant to her: purity, electricity and love. Because of her health – she had surgery all her life, more than 30 operations – she was at home a lot so it had to be a comfortable place where she could rest. Many of her still lifes were done in the garden. She called her home A Place Full of Places." It's a perfect description. For this is a breathtakingly evocative location, even leaving aside the fact that Trotsky lived here for two years with his wife, having a brief affair with Kahlo. The Artistic Legacy Tours begin in the living room, with its hefty pyramid-style fireplace designed by Rivera and, as an old photo shows, once flanked by two of his macabre Judas dolls, papier-mache devils that are stuffed with fireworks and set alight at festivals. Opposite is Kahlo's mesmerising portrait of her beloved photographer father, painted 15 years after he died, his eyes as captivating as hers. On the walls, photos and texts detail the polio Kahlo contracted at the age of six, leaving her with one shorter leg, and the trolley-bus crash at 18 that impaled her on an iron handrail and left her in pain for much of her life, as well as unable to have children. She could never paint this accident, even though what she did paint was often deeply painful and personal – and these works were largely created at Casa Azul, upstairs in her studio, where visitors can see the easel adapted to allow her to use brushes lying on her back or seated in her wheelchair.

92-Year-Old Survivor Details Brutal West Bank Mosque Arson by Israeli Settlers

A 92‑year‑old Palestinian‑American recounted a violent settler arson attack on the al‑Marah mosque …
Lead: Elderly Witness Highlights Escalating Settler ViolenceYasser Saqer Rashid, a 92‑year‑old Palestinian‑American, described how masked Israeli settlers stormed the al‑Marah mosque in Deir Dibwan after Maghrib prayer, poured an incendiary substance on a window and threatened to burn him alive. The attack, captured on surveillance footage, also saw six local vehicles set ablaze and a second mosque, al‑Noor in Burqa, torched shortly thereafter. Arson Attack on al‑Marah Mosque in Deir DibwanWhile reading the Quran inside the mosque, Rashid was interrupted by a commotion outside. Settlers entered the courtyard, broke into inner rooms, and used a petrol bomb against Rashid before igniting nearby vehicles. The structural damage to the mosque remains unclear, but the coordinated nature of the assault was confirmed by Mansour Mansour, mayor of Deir Dibwan, who said three groups simultaneously targeted the mosque, homes, and agricultural assets. Data Analysis: Scale of Settler‑Driven Attacks in 20261,659 attacks documented by the Colonization and Wall Resistance Commission in May 2026.551 of those were carried out exclusively by settlers.436 attacks on Palestinian properties, including 215 incidents of vandalism.Destruction of 7,222 trees, including 3,317 olive trees, across 124 attacks on agricultural land.At least 13 Palestinians killed in the West Bank this year (UN data).New settler outposts since October 2023: 165, with 89 established in 2025 alone. Impact Analysis: Human Cost and Political RamificationsThe attacks on al‑Marah and al‑Noor mosques are part of a documented pattern of targeting Palestinian religious sites; in May 2026 alone, 22 attacks on Muslim worship places were recorded, primarily in the Hebron governorate. The violence has forced families like the Faqih household in Beit Imrin to fortify their homes with barbed wire after a settler raid that triggered a premature birth; baby Saleh now battles serious health complications in a Ramallah ICU.Internationally, Rashid appealed directly to Washington for protection of Palestinian Americans, highlighting the limited value of his U.S. passport amid settler aggression. Human‑rights groups, including Amnesty International, label the systematic displacement of Palestinians as part of an Israeli policy of ethnic cleansing, a claim reinforced by recent Israeli moves to seize planning authority over the Ibrahimi Mosque. Prediction: Prospects for Escalation and Diplomatic ResponseIf the current trajectory continues—marked by frequent arson, property destruction, and the rapid expansion of outposts—settler‑driven violence is likely to intensify, further destabilizing the West Bank and complicating any two‑state solution. Increased documentation by NGOs and heightened media attention may pressure foreign governments to reconsider diplomatic engagement, but without decisive action from Israeli authorities to curb settler impunity, the cycle of attacks and displacement is expected to persist.

Young People with Disabilities Planting London's Future Green Ring

Young adults with learning disabilities are transforming London's environment through the London Tr…
The Lead: A Green Revolution Around London Young adults with learning disabilities are at the forefront of an ambitious environmental project to create a ring of nature around London. Through the London Tree Ring initiative, these individuals are not only transforming urban spaces into thriving wildlife habitats but also gaining valuable employment skills in the growing green sector. The Event Details: The London Tree Ring Project In Hadley Wood, north London, 20-year-old Harry Ewing and others with learning disabilities are actively participating in the London Tree Ring project. They're planting willow, hornbeam, and hazelnut trees to diversify the forest's age structure and strengthen its biodiversity. The project, which began in 2023, is being carried out by the countryside charity CPRE London with the goal of creating an "M25 for nature" – an unbroken ring of green around the capital. The Data Analysis: Scale and Scope of the Initiative The London Tree Ring project represents a monumental 25-year environmental undertaking. Since its inception, it has partnered with dozens of groups, landowners, councils, and volunteers to establish showcase sites that enhance London's biodiversity. The project has already seen implementation in various locations including Hounslow (community tree nursery), Sutton (micro forest), and Chessington (disease-resistant elm trees). The Impact Analysis: Dual Benefits for Environment and Employment This initiative addresses two critical challenges simultaneously: environmental degradation and employment barriers for people with disabilities. The young participants, through the Harington Scheme charity, are gaining practical conservation skills that future-proof their employability as the UK economy becomes increasingly green. Simultaneously, the project creates vital wildlife corridors that help halt nature decline by establishing bigger, better-connected, and more diverse habitats. The Prediction: Growing a Greener Future Over the next two decades, the trees planted by these dedicated young gardeners will mature and connect with other sections of the tree ring, forming a comprehensive ecological network. The project's philosophy extends beyond simply planting trees – it focuses on restoring various ecosystems by developing brownfield sites and improving existing natural environments. As Phil Paulo, director of London Tree Ring, emphasizes, the goal is to create "bigger habitats that are better connected and more diverse" – the key to halting nature decline while providing meaningful employment opportunities for marginalized communities.

The Fight for Jamaica's Coast: Challenging the 'Plantation Tourism' Model

Jamaican communities are suing the government and developers to reclaim public beaches like Mammee …
The Rise of 'Plantation Tourism' in JamaicaFor Devon Taylor, the Mammee Bay shoreline in St Ann is not just a tourist destination; it is a lifeline. Growing up on the coast, Taylor recalls a vibrant ecosystem of children swimming, fishers haggling, and vendors carving souvenirs under almond trees. Today, that scene has been replaced by a fortress mentality. Taylor, founder of the Jamaica Beach Birthright Environmental Movement (Jabbem), describes the current reality as a war against a multibillion-dollar all-inclusive tourism model. He argues that this model, which he terms 'plantation tourism,' is designed to benefit wealthy visitors and the elite while systematically disadvantaging the local population.Legal Battles Over Crown LandThe conflict has escalated from community protests to high-stakes litigation. In 2019, locals were physically locked out of Mammee Bay by fences and armed security hired by luxury hotel investors. After a violent displacement involving gunshots, the community reoccupied the beach, only to find concrete walls erected in their absence. This struggle is not isolated; it is part of a broader legal offensive involving five separate court cases. Key locations under dispute include Mammee Bay, Little Dunn's River, the Blue Lagoon, Bob Marley beach, and Flankers/Providence beach in Montego Bay. The legal foundation of this battle rests on the 1956 Beach Control Act, which grants the state ownership of the foreshore and seabed, effectively requiring locals to seek government permission to access their own coastline.The Economic Cost of ExclusionThe data reveals a widening gap between the economic value of Jamaica's natural assets and the distribution of that wealth. While tourism is the backbone of the Jamaican economy, the current model generates revenue that largely leaves the country or remains concentrated among the elite. Campaigners argue that the closure of beaches like the Blue Lagoon in Portland—promised to reopen in 90 days but effectively closed permanently to facilitate private villa construction—represents a theft of public resources. The economic impact is twofold: the loss of income for local vendors and fishers, and the loss of a low-cost recreational space for families who cannot afford expensive all-inclusive packages.Scale of Conflict: Five active court cases involving multiple high-profile beaches.Legal Status: Disputed 'crown land' inherited from colonial times, managed by a 1956 Act.Community Impact: Loss of fishing grounds, vending opportunities, and cultural spaces.Colonial Legacies in Modern TourismThe activists' argument extends beyond economics to the psychological and social fabric of the nation. Critics, including Taylor, compare the government's justification for restricting access—citing crime prevention—to the colonial logic of 'keeping out the savages.' They view the current restrictions as a modern continuation of colonialism, where the local population is considered unworthy of enjoying their own natural heritage. This 'plantation' mentality, they argue, treats the local community as a labor force rather than stakeholders in the tourism product.Future Outlook: Parks vs. Private AccessThe government has attempted to mitigate these tensions by announcing new public spaces, such as the Harmony beach park in Montego Bay and the Success beach park in St James. However, these state-led initiatives may not satisfy the demands of communities fighting for access to specific, historically significant sites like the Blue Lagoon. The upcoming trials later this month will be a critical test of the legal system's willingness to challenge the entrenched interests of the all-inclusive tourism sector. If the courts rule in favor of the communities, it could force a fundamental restructuring of how Jamaica manages its coastline, shifting the balance from exclusive private control to public access.

David Hockney's Impact on Art: 10 Ways He Changed the Game

David Hockney, a renowned artist, has left an indelible mark on the art world. From his innovative …
The Legacy of David Hockney David Hockney didn't just appear out of nowhere like some fully formed artistic wunderkind. His work was a synthesis of so much that came before and was happening around him. He took the ideas of minimalism and abstraction, fused them with the traditions of portraiture, and filtered it all through the innovations in pop and conceptualism that were going on in the 1960s. Breaking with Convention Working-class boys from Bradford didn't go to art school. It just wasn't the done thing. That was for other people. But Hockney was born to subvert expectations. He told the Guardian in 2015: 'When I went to art school, a neighbour said, 'Some of the people in the art school just don't work at all. Lazy buggers.' And I said, 'Oh I am going to work, don't worry.' And he did, incessantly, unstoppably, right to the very end. Revolutionizing Perspective Hockney saw traditional perspective – with all lines leading to a single, distant vanishing point – as not just reductive and boring, but totally unrealistic. We don't see the world as frozen and static, he thought, our vision is dynamic, constantly shifting. Reverse perspective was his solution: he shifted the vanishing point, putting it behind the viewer, or splitting it off in multiple directions. The Intersection of Photography and Painting Photography was central to Hockney's practice for decades. In more recent years, he incorporated photos directly into his paintings, but his best work with the medium was his collages, where he took multiple snaps of the same thing from multiple angles (often with a Polaroid), creating kaleidoscopic visions of the world around him. Making the Mundane Monumental Yorkshire became Hockney's muse in the mid-2000s, and he returned repeatedly to the undulating hills around Bridlington. In 2007, the forest in Woldgate inspired him to push the idea of landscape to its absolute extreme – he wanted to paint the countryside on a scale that was reserved by art's big, important subjects: history, scenes from the Bible, national liberation. Embracing Technology He wasn't shy about adopting new technology, and in his later years took to the iPad with abandon. Painting directly using a digital stylus or his finger allowed him to be immediate and direct. Many critics hated the iPad works, decrying the 'loss of the artist's hand' or describing them as 'unaccountably messy', but what's incredible is that even on this new, digital, strange medium, his works are immediately recognisable. Capturing the Essence of Los Angeles It took a boy from deepest West Yorkshire to truly capture the sun-drenched, humid beauty of Los Angeles. Hockney moved to California in 1964, and spent the next few decades creating hyper-stylised, ultra-cool visions of life among the palm trees, pools and PoMo architecture of Hollywood and its environs. The Power of Portraiture Portraiture was at the heart of Hockney's art from the very beginning. His images of his mother are tender and adoring, his portraits of lovers are intimate and sweet. It didn't matter if he was painting a Rothschild or his cousin, a pop star or a studio assistant, he treated everyone with the same grace. Pioneering Immersive Art Immersive art became the trend du jour in all the big museums in the early 2020s, and Hockney wasn't about to be left behind. He took over London's Lightroom venue with Bigger & Closer (not smaller & further away) in 2025, part-autobiographical documentary, part-digital art exhibition. A Life of Creativity and Self-Expression Hockney's earliest works were filled with carnal, libidinal imagery: enormous phalluses, bodies chaotically intertwined. They were very randy things, and that was a brave thing for a young gay artist to be doing back in the 1960s, even in swinging London. Hockney's sexuality was always central to his work, and that helped pave the way for a lot of other gay artists to feel free to express themselves too.

Trees May Store Less Carbon Than Hoped, Study Suggests

A new study suggests that trees may not store as much planet-heating carbon as previously thought, …
The Carbon Storage Conundrum Trees may not be able to store as much planet-heating carbon as hoped, a study suggests, with researchers finding photosynthesis does not always lead to wood growth. Photosynthesis and Wood Growth Decoupling Scientists studied 137 sites across the US and found trees stopped growing months before the point in the year at which photosynthesis stopped. Forests are a vital defence against climate breakdown but their power depends in part on how much carbon dioxide they can convert into wood, which keeps the planet-heating molecule out of the atmosphere for decades and centuries. The Data Analysis At sites in the eastern US, the researchers found about 36% of yearly carbon uptake occurred after the tree growth stopped in late summer. At sites in California, it was about 26%. More detailed measurements at four sites showed wood growth was restricted to periods of low aridity and temperature, which are becoming rarer as the global rise in temperature makes heatwaves and droughts more common. The Impact Analysis “The moment you have dry and hot conditions, growth activity stops pretty instantly, while photosynthesis seems to continue at a slightly decreased rate,” said Mukund Palat Rao, a carbon cycle scientist at the Lamont-Doherty Earth Observatory at Columbia University and lead author of the study. This decoupling of photosynthesis and wood growth has significant implications for carbon sequestration models. The Prediction The researchers are now studying whether the decoupling of photosynthesis and wood growth they observed can be seen in other tree species and regions. They said their results showed the capacity of forests to store carbon over long periods depended on how much carbon was absorbed and then directed towards wood growth. If more of the absorbed carbon were to flow toward transient uses – such as foliage and internal processes – the power of forests as carbon sinks would fall. “Earth system models that assume consistently tight coupling between photosynthesis and growth may therefore overestimate future forest carbon sequestration under rising atmospheric moisture demand,” the researchers wrote.
