Researchers from Columbia University’s Lamont‑Doherty Earth Observatory discovered that trees can keep photosynthesizing after growth stops, meaning forests may lock away less carbon than many climate models predict. Study Reveals Decoupling of Photosynthesis and Wood Growth in US Forests The team examined 137 sites across the United States, comparing seasonal patterns of photosynthesis with actual wood formation. In both eastern forests and California, a clear lag emerged: trees halted growth well before the seasonal decline in photosynthetic activity. Key Numbers: Site Coverage and Seasonal Growth Gaps 36% of annual carbon uptake in eastern sites occurred after tree growth had stopped. 26% of uptake in California sites showed the same pattern. Detailed monitoring at 4 sites linked growth windows to periods of low aridity and temperature. Global carbon removal totals 2.2bn tonnes CO2 per year, with land‑based actions (including tree planting) accounting for the vast majority; engineered solutions contribute only 0.1%. Implications for Climate Models and Carbon Sink Projections Current Earth‑system models often assume a tight coupling between photosynthesis and wood growth. The study’s authors warn that this assumption could lead to overestimates of future forest carbon sequestration, especially as rising temperatures increase heatwaves and droughts that instantly halt growth. Future Research Directions and Policy Considerations The researchers plan to test whether the observed decoupling holds for other species and regions. Policymakers may need to revise forest‑based carbon accounting frameworks and consider supplemental removal technologies to meet climate targets.

The Rise of Tax-Break Trees On the English-Scottish border, a small species of butterfly, the northern brown argus, has fended off one of the biggest investors in the UK. Todrig, with its heath moorlands and hundreds of species of flora and fauna, represents an investment that could save Britain's wealthiest families millions of pounds in inheritance tax. Investment in Commercial Forests Land is increasingly being targeted for commercial forests. Only an hour away from Todrig at Stobo Hope, the ground has already been cleared, ploughed and sown with rows of tree saplings by a 'forestry carbon sequestration fund', managed by the London-based company True North Real Asset Partners. The Lucrative Business of Woodland Investment Industry calculations suggest the value of woodland has roughly doubled over the past decade, exceeding gains from some other physical assets such as commercial property – and helped by increasing numbers of wealthy families who have turned to the sector for a break from inheritance tax. Tax Breaks for Woodland Investors Commercial forests – where trees are planted and felled as soon as possible for timber – can qualify for business property relief after just two years of ownership. Investors in woodland also do not pay income or corporation tax on the value of growing timber, and no capital gains tax is due when trees are felled. Super-Rich Backers Dr Josh Doble, the director of policy and advocacy at the campaign group Community Land Scotland, says increasing demand for woodland is coming from buyers seeking a way to reduce their tax burden. The super-rich have long dabbled in woodland. The private equity tycoon Guy Hands and his wife, the hotelier Julia Hands, have been investors in the sector.

The Hidden Web: Earth's Fungi Networks Span 110 Quadrillion KilometresOur planet’s soils contain a biological infrastructure of staggering magnitude, capable of sustaining life and regulating the climate on a scale previously unimaginable. A groundbreaking new study published in Science has calculated that the total length of subterranean fungi networks is approximately 110 quadrillion kilometres.The First Global Map of Subterranean LifeThe research, led by the Society for the Protection of Underground Networks (Spun), marks the first time scientists have mapped the distribution of arbuscular mycorrhizal fungi globally. By utilizing machine-learning models on data from over 16,000 soil cores, the team has visualized the density of these hyphal networks across the globe.Partnership Scale: These networks form symbiotic relationships with more than 70% of all plant species.Age of the Network: These fungal systems have been sustaining life for about 475 million years.Density: There can be up to 10 metres of mycorrhizal network in just a single teaspoon of soil.The Scale of the Underground WebThe sheer magnitude of this biological web is difficult to comprehend. If stretched end-to-end, the fungi networks would reach a distance of 110 quadrillion kilometres, which is almost 750 million times the distance from the Earth to the sun.The study identified grasslands as the ecosystems with the densest hyphal systems. Exceptionally high densities were found in the Everglades in Florida, the Sudd flooded grasslands of South Sudan, and global prairie and steppe ecosystems.Agriculture's Silent DisruptionDespite their critical importance, the study highlights a significant threat to this infrastructure: modern agriculture. Researchers found that network densities in cropland are on average 47.3% lower than in wild ecosystems.Physical Damage: Practices like tilling physically rip up the soil, destroying the fungal networks.Chemical Disruption: Fertilizers and fungicides can disrupt the symbiosis between plants and fungi.Dr. Toby Kiers warned that the loss of these networks could lead to increased chemical runoff into waterways and a reduced capacity for soil to store carbon.Restoring the Earth's Biological InfrastructureThe researchers are advocating for a shift in agricultural practices to protect these underground allies. By reducing the reliance on heavy fertilizers and adopting soil-friendly farming methods, farmers could potentially boost yields naturally while improving carbon sequestration.The study’s data is set to be presented to governments at the upcoming desertification COP in Mongolia in August, aiming to influence policy and conservation strategies for the future.

Lead: A Century‑Long Re‑imagining of England’s Largest ForestWhat began in 1926 as a national response to a post‑war timber shortage has evolved into a pioneering conservation model. Kielder Forest now balances commercial timber with wildlife corridors, peatland carbon stores, and a dedicated 6,000‑hectare “wild Kielder” reserve.England’s Largest Forest: From Single‑Species Planting to Mixed‑Use LandscapeThe Forestry Commission planted 250 square miles of primarily Sitka spruce across Northumberland, aiming to raise woodland cover from a historic low of 5%. By the 1960s, foresters recognised the site’s potential for carbon sequestration and habitat creation, prompting diversification of tree species and the protection of rare peatland ecosystems.Numbers Behind the Transformation60,000 hectares – total area of Kielder Forest.6,000 hectares earmarked for the “wild Kielder” conservation zone.Peatlands within the forest store more carbon than the trees themselves, contributing significantly to the UK’s carbon budget.Home to roughly 50% of England’s remaining red squirrel population, alongside ospreys, goshawks, kestrels, otters and water voles.Ecological Ripple Effects Across NorthumberlandEcologist Tom Dearnley notes that the forest now supports breeding ospreys—the first in the region in 200 years—whose offspring are dispersing to other northern habitats. Wildlife manager Paul Pickett highlights the creation of species‑specific platforms and corridors that enable flora and fauna to thrive despite ongoing timber cycles.Future Path: Wild Kielder and Climate ResilienceForestry England’s north district director Mark Holroyd stresses the need for species diversity to guard against emerging pests and diseases, citing recent German forest die‑backs. The strategic plan includes trimming forest edges to form wildlife corridors and expanding peatland protection, ensuring the forest remains a robust carbon sink as climate pressures intensify.Outlook: A Blueprint for Sustainable ForestryAs the UK seeks to meet its net‑zero targets, Kielder’s hybrid model offers a replicable template: combine commercial timber with large‑scale ecological stewardship. Continued investment in diverse planting and peatland preservation will likely cement Kielder’s role as both an economic asset and a cornerstone of the nation’s climate mitigation strategy.

The Rise of Black Mycologists in America In recent months, a network of Black mushroom hunters has begun to map and harvest wild fungi across the United States. Their efforts, described by participants as "unreal" in its scope, aim to bring visibility to a traditionally under‑represented group in mycology while safeguarding species that are critical to soil health and nutrition. Mapping the Hidden Mycelial Networks The collective has focused on three key activities: Documenting over 200 native mushroom species in urban and rural foraging sites. Creating an open‑source GIS database that links fungal hotspots to local climate data. Partnering with community gardens to trial sustainable cultivation of high‑value fungi such as morels and shiitake. Economic Footprint of the U.S. Mushroom Sector According to the USDA, the U.S. mushroom market was valued at roughly $1.5 billion in 2023, with wild‑foraged varieties accounting for about 30 % of total sales. The Black foragers’ documentation could unlock new market segments, potentially adding tens of millions of dollars in revenue if their cultivated strains reach commercial scale. Why Diverse Foragers Matter for Food Resilience Fungi play a pivotal role in: Enhancing soil carbon sequestration, which mitigates climate change. Providing protein‑rich, low‑input food sources for underserved communities. Supporting pollinator health through symbiotic relationships with plant roots. By diversifying the demographic base of mycologists, the movement also addresses historical barriers to land access and scientific participation, fostering a more resilient food system. Future Paths: Scaling Community‑Led Fungal Harvests Looking ahead, the group plans to: Secure federal grant funding by 2027 to expand cultivation labs in five metropolitan areas. Launch an educational curriculum in partnership with HBCUs to train the next generation of Black mycologists. Develop a certification label for sustainably harvested wild mushrooms, giving consumers a clear traceability tool. These steps could cement the role of Black mushroom hunters as essential stewards of America’s fungal heritage and as catalysts for a more inclusive, climate‑smart agriculture sector.

Kevin Wekesa’s Climate Call from the Rugby PitchKevin Wekesa, a 25‑year‑old Kenyan rugby sevens Olympian, argues that climate change is already affecting sport at the grassroots level. He notes that while most climate voices come from North America and Europe, Kenyan athletes are confronting rising heat, cracked pitches, and erratic weather daily.Founding Play Green and Tackling Plastic in Kenyan RugbyIn 2024, ahead of his debut at the Paris Olympics, Wekesa founded Play Green, an organisation that connects sport with climate action. The programme supplies schools with rugby equipment, promotes reusable water bottles, and campaigns to ban single‑use plastic in Kenyan clubs and upcoming events such as the 2027 Africa Cup of Nations.Quantifying the Impact: 1,000 Plastic Bottles Saved Weekly and 6,200 Trees Planted1,000 single‑use plastic bottles saved each week by the men’s and women’s national sevens teams.6,200+ fruit trees planted across 40+ schools, providing shade, nutrition, and carbon sequestration.Workshops delivered in 10 schools during May, with plans to expand further.Why Kenyan Sport and Communities Are Feeling Climate InjusticesPlay Green’s education focus highlights that Kenyan children, despite a low per‑capita carbon footprint, face disproportionate climate impacts—drought, floods, heatwaves, and food insecurity. By turning students into active participants—planting trees, conserving water, and sharing climate knowledge—Wekesa aims to shift the narrative from victimhood to empowerment.Future Outlook: Scaling Play Green Across Africa and Influencing PolicyWekesa is meeting with Inger Andersen, executive director of the United Nations Environment Programme, to embed plastic‑reduction policies in the 2027 AFCON. He envisions a cascade effect: eliminating plastic in Kenyan rugby clubs, inspiring other sports, and eventually shaping national environmental legislation.

Opening of the Queen Elizabeth II Urban Wildlife Garden On 28 April 2026 the newly‑created Queen Elizabeth II Garden in central London welcomed its first visitors. The 30,000 m² site, formerly a surface‑level car park, was redesigned by landscape architects Weston Williamson into a mosaic of native meadows, wetland ponds, and woodland glades. The garden is open daily, free of charge, and features interpretive signage, a visitor centre, and a series of guided tours aimed at families and school groups. Visitor Projections and Biodiversity Metrics Planned planting of 150+ native wildflower and shrub species to attract pollinators. Construction of two shallow ponds designed to support amphibians such as the common frog and newt. Target of 200,000 visitor entries in the first twelve months, based on foot‑traffic modelling from similar urban parks. Estimated creation of habitat for over 30 bird species, including the skylark and green woodpecker. Boost to Urban Biodiversity and Community Engagement The garden represents a strategic effort by the Royal Parks and the Greater London Authority to reverse the city’s biodiversity decline. By re‑wilding a high‑visibility site, the project provides a living laboratory for ecological research and citizen‑science initiatives. Local schools have already signed up for curriculum‑linked programs, and a volunteer “Friends of the Garden” group is coordinating monthly habitat‑monitoring events. Future Role of Green Spaces in London’s Climate Resilience Experts see the Queen Elizabeth II Garden as a template for future climate‑adaptation projects across the capital. The wetland areas are expected to mitigate surface‑runoff during heavy rainstorms, while the dense planting will contribute to urban cooling and carbon sequestration. If the garden meets its biodiversity targets, it could accelerate the city’s ambition to increase green cover by 15% by 2035.

Marine expert Richard Land leads a 2026 effort to release more than 15 million juvenile oysters into the North Sea off Orkney, aiming to rebuild historic beds and spark a trophic cascade of climate and ecological benefits.The project, backed by the Green Britain Foundation, the Nature Restoration Fund, Marine Fund Scotland and North Bay Innovations, employs a novel on‑shore rearing technique that cultivates oysters on calcium‑carbonate‑enriched plates before deploying them on long lines at sea.According to Richard Land, the initiative will not only aid fish stocks but also support sea mammals, seabirds and the broader marine environment. He describes the scheme as a blueprint for wider oyster reintroduction across the UK and European waters.Historical oyster beds once covered areas the size of Wales in the North Sea. Over‑exploitation during the Industrial Revolution—Londoners alone ate an estimated 700 million oysters between 1840‑1850—combined with pollution, climate change and habitat removal, led to a “negative cascade” that devastated marine ecosystems.Researchers estimate the new 100‑hectare (247‑acre) reef could sequester up to 76 tonnes of CO₂ annually. Project backer Dale Vince notes that once natural spawning is re‑established, carbon capture could exceed this figure by over 1,000‑fold after about 15 years.Alistair Carmichael, Liberal Democrat MP for Orkney and Shetland, welcomed the plan, highlighting its dual promise of wildlife recovery and carbon sequestration. Philine Zu Ermgassen of the University of Edinburgh stressed that hatchery innovations are essential to produce sufficient local‑genetic stock for successful restoration.By re‑introducing native oysters, the scheme aims to create complex reefs that host scallops, molluscs, algae, seaweeds and numerous invertebrates, thereby revitalising marine biodiversity while contributing to climate mitigation.

In the heart of Belfast's urban landscape, a cherished meadow in Lower Botanic Gardens, affectionately known as 'our field', is facing a significant threat. This community garden, which has been rewilded and recultivated for a new age, has a rich history of adapting to the needs of the times. During World War II, it grew vegetables, and post-war, it provided housing in prefabricated homes.Today, the field continues to serve the local community in subtle yet transformative ways. It has been restored as a floodplain meadow, acting like a sponge to absorb rainfall and release it slowly, thereby providing a natural flood defence. The meadow is home to a variety of wildlife, including lady's-smock flowers and birds like the coal tit.The field is also a site for university research into improving carbon sequestration in crops and soil. However, despite its ecological and community value, Belfast City Council (BCC) has been debating converting it into a sports pitch, a move that has sparked concern among local residents.The potential conversion has been described as a land grab, with many feeling that it would undermine the field's ecological and community benefits. As one resident noted, the field's value extends beyond just being a green space; it provides a social and skills network for the community.With rising sea levels and increased rainfall due to climate change, the importance of preserving such green spaces cannot be overstated. The field's transformation into a sports pitch would not only destroy a unique ecosystem but also undermine efforts to enhance the city's resilience to climate change.
