A study of policymakers across five European regions reveals that nature-based climate solutions overlook the needs of non-human species, treating them as side benefits rather than stakeholders. Experts say reframing adaptation projects as collaborative partnerships between humans and nature could unlock more effective and equitable climate strategies.EN

A new study reveals that nocturnal birds' annual life cycles—including migration and reproduction timing—are synchronized to the moon's monthly rhythm, not just seasonal changes. The finding suggests lunar cycles may be far more consequential to wildlife management and ecosystem planning than previously recognized, with implications for conservation strategies facing rapid environmental change.EN

A comprehensive new analysis reveals how black carbon—soot from fossil fuels and biomass burning—warms the atmosphere far more effectively than previously understood. The findings could reshape climate policy and air quality regulations, forcing industries and governments to prioritize soot reduction alongside carbon dioxide cuts.EN

Researchers have validated Erik Granlund's early 20th-century observations of climate transitions in peatlands, confirming his findings align with globally recognized climate events. The work strengthens peatlands' credibility as climate archives for predicting future environmental changes—critical for policymakers and companies planning long-term climate strategy.EN

A major new analysis reveals that old-growth boreal forests in Sweden sequester far more carbon than previously thought—72% more than managed secondary forests when accounting for soil, vegetation, and wood products combined. The finding undermines assumptions about forest management's climate benefits and could reshape carbon accounting in climate policy and corporate sustainability strategies.EN

A 14-year study in Swedish Subarctic tundra reveals that nitrogen fertilization alone changes plant communities modestly, but combining nitrogen and phosphorus triggers dramatic shifts in vegetation composition. The finding matters because Arctic regions are warming rapidly, altering nutrient cycles—and these results show how nutrient changes could reshape carbon storage and ecosystem services across vast northern landscapes.EN

The European Union has developed OCEANIS, an operational framework designed to coordinate ocean observation projects that currently operate in silos across sectors and regions. The tool could help governments and businesses better track climate impacts, biodiversity loss, and ecosystem health—critical for managing marine resources and meeting climate targets.EN

The result opens a path to cheaper, more reliable monitoring of electrolyzer performance without expensive additional sensors.EN

A new study exposes a critical gap in how the world forecasts climate futures: the tools used by governments and businesses to plan emissions cuts and adaptation strategies don't account for political change. Researchers say integrating political dynamics into climate scenarios could reshape investment priorities and policy timelines.EN

Researchers discovered that everyday pharmaceuticals like diabetes and cancer drugs account for nearly 40% of fluorine pollution in wastewater—far more than previously suspected toxic "forever chemicals." The finding reshapes how regulators should monitor water safety and signals that drug manufacturers may need to reformulate products to reduce fluorine content.EN

A 57-year study of Swedish forests reveals that higher atmospheric carbon dioxide is reducing nitrogen availability in trees—a finding that could reshape how companies and governments assess forest productivity and carbon sequestration potential. The discovery challenges assumptions about how forests will respond to climate change and may require new strategies for forestry management.EN

Blinda fläckar i kunskapen om kemikalier, avfall och föroreningar hotar miljöpolitikens effektivitet, särskilt i låginkomstländer och utsatta samhällen. Den nystartade panelen ISP-CWP (Intergovernmental Science-Policy Panel on Chemicals, Waste, and Pollution) behöver framtidsspaning för att identifiera framväxande risker som dagens övervakning missar. Forskare från Wageningen University, universiteterna i Concepción, Uppsala, Stockholm, Monash och Toronto presenterar en vägledning för att anpassa horisontscanning efter olika aktörer, målgrupper och teman. Metoden fokuserar på tre dimensioner: vilka ämnen som adresseras, vilka aktörer som involveras, och vilka analysmetoder som tillämpas. Tillvägagångssättet betonar korrigering av kunskapsobalanser, integrering av lokal och ursprungsbefolkningens kunskap, samt legitimitet i global styrning. För beslutsfattare ökar detta möjligheten att forma förebyggande miljöpolitik och säkerställa rättvis hantering av kemikalier och föroreningar globalt.

Researchers have reclassified a ubiquitous family of ocean bacteria that live inside corals, sponges, and fish, splitting them into two distinct genera to better reflect their evolutionary history. The fix could improve how scientists study these symbiotic relationships—critical for understanding coral reef health and aquaculture disease management.EN

Swedish researchers tested whether industrial alkaline waste from pulp mills can safely remediate abandoned mine sites. The waste leaches easily soluble salts but holds onto most heavy metals—a finding that could unlock a circular economy solution for the paper industry, provided regulators approve strict handling protocols.EN

Scientists have developed a practical roadmap for achieving "Nature Positive" — a fundamental shift where ecosystem health becomes the foundation of economic stability. The framework identifies critical gaps in current global biodiversity commitments and provides a classification system for determining where conservation efforts will have the greatest impact on both nature and human prosperity.EN

A major new analysis tracking global glacier loss in 2025 reveals accelerating ice melt across all regions, with direct implications for water availability, hydropower generation, and coastal flood risk. The findings underscore why governments and companies investing in water infrastructure and climate adaptation strategies need updated baseline data on glacier behavior.EN

Atlantic salmon exposed to cocaine metabolites in a Swedish lake swam nearly twice as far as normal and dispersed across vastly larger distances, a new study shows. The finding raises urgent questions about how drug pollution—increasingly detected in rivers and lakes worldwide—may be disrupting fish populations and ecosystem balance in ways that threaten fisheries and freshwater management.EN

Valet av trädarter för långsiktig skogsbeskattning och klimatanpassad reglering beror på arter som kan balansera vattenledning med torktålighet. Uppsala universitet och internationella samarbetspartners kartlade hur växtkärlens anatomiska struktur bestämmer denna balans hos 13 tropiska arter i Puerto Rico. Forskarna identifierade en tydlig motsättning: arter med högre vattenledningsförmåga var mer känsliga för embolism (luftblockeringar som stoppar vattentransport). Motsatt vad tidigare teori förutspått var kärldiametern inte avgörande. Istället var kärlnätverkets sammanhang kritiskt — arter med fler isolerade kärl visade större embolismrisk. Resultaten visar att tropiska träd koordinerar två hydrauliska strategier: torktålighet (lågt Ψ₅₀) och torkundvikande (högt vatterlager). För investerare i klimatrobusta skogar och infrastrukturplanerare blir arten av valet nu evidensbaserat: anatomiska signaturer förutsäger vilka arter som överlevde framtida torka utan att offra tillväxt.

Skogsövertagandet av savannen accelererar snabbare än tidigare antagits. Forskare från Sveriges Lantbruksuniversitet kalibrerade en reaktions-diffusionsmodell med satellitdata från Kamerun och måtte skogsfrontens framryckningshastighet till 5–7 meter per år — två till tio gånger högre än tidigare uppskattat. Studien använder 50 års Landsat-bilder från Mpem och Djim nationalpark för att kvantifiera växtwöde sprids genom landskapet. Modellen simulerar växelspelet mellan gräs- och vedartad biomassa och ger första gången uppskattningar av trädens dispersionskoefficienter. Resultaten är centrala för klimat- och markanvändningsplanering i tropikalt Afrika: snabbare skogsexpansion förändrar koldioxidlagring, vattenbalans och mark­nyttningskonflikt. För investerare och infrastrukturplanerare blir det kritiskt att uppdatera prognoser för vegetationsdynamik i savannsystemet under kommande två decennier.

Researchers reviewed decades of school-based biodiversity education studies to identify which teaching methods stick with students. The findings could help schools, education publishers, and conservation nonprofits design more effective programs—and clarify where billions in environmental education spending yields real behavioral change.EN

Researchers found that expectant mothers exposed to nitrogen oxide and fine particulate matter during late pregnancy had children more likely to develop food sensitivities by 18 months. The trimester-specific findings suggest a critical window for intervention, with implications for urban planning, industrial regulation, and prenatal health guidance.EN

A major health tracking study finds European nations are falling short on climate adaptation and mitigation efforts needed to protect public health. The 2026 Lancet Countdown report identifies widening health inequalities and calls for urgent action before critical tipping points arrive—signaling significant risks for healthcare systems and economies if governments don't accelerate intervention.EN

A new framework distinguishes between restoring lost ecosystems and artificially boosting biodiversity in ports and offshore structures. For project developers and regulators, the distinction matters: it determines whether investments align with environmental goals or inadvertently introduce non-native species.EN

A Nature study finds that 86.6% of the world's land lacks adequate rainfall monitoring networks, crippling efforts to predict water scarcity and climate impacts. The shortfall is most acute in high-risk regions like India, Central Africa, and northern South America—areas where businesses and governments desperately need reliable data to manage water resources and climate adaptation.EN

Researchers discovered that PFAS—forever chemicals used in industrial applications—are being transported across hemispheres and deposited across East Antarctica via atmospheric currents and sea spray. The 50-year record suggests sources thousands of miles away are contaminating one of Earth's most isolated regions, raising questions about how thoroughly these persistent toxins spread globally.EN
