New research has uncovered why different climate models offer varying projections of sea surface temperature (SST) changes in the tropical Pacific, a region critical for global climate patterns. The study, published in Advances in Atmospheric Sciences on March 5, identifies cloud–radiation feedback as the dominant source behind these differences. Reliable projections of the tropical Pacific SST warming (TPSW) pattern are crucial for understanding how global climate will change in a warming world. While the latest climate models from the Coupled Model Intercomparison Project Phase 6…
Reliable and accurate monitoring of CO2 emissions is a cornerstone of effective climate change mitigation strategies. While traditional methods largely depend on ground-based measurements and bottom-up inventories, these approaches are often resource-intensive and prone to errors. Satellite Technology has emerged as a promising alternative, but the challenge remains in distinguishing anthropogenic emissions from natural processes. The long atmospheric lifetime of CO2 makes it difficult to pinpoint localized sources of emissions and track changes over time. Additionally, natural emissions and background concentrations can…
Researchers at Göttingen University show keys to nature conservation measures at landscape level How can the loss of species and habitats in agricultural landscapes be stopped? Up to now, measures have mostly been implemented by individual farms. In contrast, agri-environmental measures that are planned across farms at landscape level offer greater potential for creating suitable habitats for different species as a mosaic in the landscape. However, successful landscape level approaches also require cooperation between farms and other stakeholders from local…
Using underwater microphones and machine learning (ML), Cornell University researchers have developed a new method to estimate North Atlantic right whale numbers — offering a potentially safer and more cost-effective way to monitor this critically endangered species. Their study, published in Endangered Species Research, demonstrates how microphones combined with ML and traditional aerial survey methods can help track right whale populations in Cape Cod Bay, a crucial feeding ground where the whales gather each spring. To track this endangered species, researchers…
A new study led by the University of Cambridge has revealed that as our springs and summers get hotter and drier, the UK wildfire season is being stretched and intensified. More fires, taking hold over more months of the year, are causing more carbon to be released into the atmosphere as carbon dioxide. Fires on peatlands, which are carbon-rich, can almost double global fire-driven carbon emissions. Researchers found that despite accounting for only a quarter of the total UK land…
A field study spanning a year showed that water collected from fog could ease water scarcity affecting vulnerable populations living in Chile’s Atacama Desert With less annual rainfall than 1 mm per year, Chile’s Atacama Desert is one of the driest places in the world. The main water source of cities in the region are underground rock layers that contain water-filled pore spaces which last recharged between 17,000 and 10,000 years ago. Now, local researchers have assessed if ‘fog harvesting,’…
Feeding success and demography of a marine mammal provide a multi-decadal ecological baseline to assess impacts of a new fishery and environmental change Over the past 60 years, marine biologists at UC Santa Cruz have monitored the behavior of northern elephant seals that journey to nearby Año Nuevo Natural Reserve. With the seals gathering on the beach by the thousands to breed and molt, generations of researchers have been able to amass more than 350,000 observations on over 50,000 seals….
Polythioenones: a step toward a circular economy for synthetic polymers The possibilities for material design and production of plastic components are being expanded through 3D printing technology. However, there is a shortage of recyclable polymers that meet the performance requirements. In the journal Angewandte Chemie, a research team has introduced a new class of polymers called polythioenones, which are mechanically and chemically recyclable and suitable for 3D printing. They also demonstrate better mechanical properties than conventional polyolefins—thanks to a special,…
Despite 2023 and 2024 ranking as the warmest years on record, extreme cold events still gripped parts of China, Europe, and North America. A new study published in npj Climate and Atmospheric Science investigates the paradox of these record-breaking cold spells and assesses future risks in a changing climate. Led by Professor Qian Cheng from the Institute of Atmospheric Physics at the Chinese Academy of Sciences, in collaboration with Dr. Aiguo Dai from the University at Albany, State University of New York,…
A system-wide evaluation of California’s marine reserve network finds conservation benefits across multiple ecosystems (Santa Barbara, Calif.) — It’s 1999, the 21st century is on the horizon, and California has big plans for marine conservation. New legislation has presented a mandate to establish an ambitious network of marine protected areas (MPAs) unlike anywhere else in the world. The goal is to craft strategic protections to safeguard the state’s marine life for preservation and economic benefits alike. Now 25 years later,…
Researchers have developed a sustainable catalyst that increases its activity during use while converting carbon dioxide (CO2) into valuable products. This discovery offers a blueprint for designing next-generation electrocatalysts. A collaborative team from the University of Nottingham’s School of Chemistry and the University of Birmingham have developed a catalyst made of tin microparticles supported by a nanotextured carbon structure. The interactions between the tin particles and graphitised carbon nanofibers play a critical role in transferring electrons from the carbon electrode…
Research shows health and economic costs of air pollution in Japan Air pollution is a growing health issue worldwide, and its impacts are often underestimated in aging societies like Japan. A new study led by researchers from the University of Tokyo highlights how fine particulate pollution, or PM2.5, not only worsens health outcomes, but also creates significant socioeconomic challenges in regions with aging populations and limited medical resources. The researchers hope these findings motivate policymakers to tackle the interrelated issues…
A new study of the Great Barrier Reef has revealed that the network of no-take marine reserves supplies nearly half of the region’s coral trout fishery catch. The research, led by Professor Michael Bode from the QUT School of Mathematical Sciences and published in Science Advances, revealed that despite covering only 30 per cent of the reef’s habitat, these protected areas account for 47 per cent of the coral trout catch in fishing areas and contribute 55 per cent of…
Improved approach to marine conservation aligns ecological restoration with human well-being Could 2025 be the year marine protection efforts get a “glow up”? According to a team of conservation-minded researchers, including Octavio Aburto of UC San Diego’s Scripps Institution of Oceanography, the moment has arrived. In a new study published Feb. 6 in the journal Frontiers in Marine Science, Aburto and a multinational team of marine scientists and economists unveil a comprehensive framework for Marine Prosperity Areas, or MPpAs. With…
A new study has estimated it would cost $15.6 billion per year for 30 years to prevent extinction for 99 of Australia’s priority species. The research, led by Griffith University’s Centre for Planetary Health and Food Security with WWF-Australia and the University of Queensland, highlights the urgent need for increased funding to combat threats such as habitat destruction, invasive species and climate change. Australia has already lost more than 100 endemic species in the past three centuries, placing it at…
Recycling lithium-ion batteries to recover their critical metals has significantly lower environmental impacts than mining virgin metals, according to a new Stanford University lifecycle analysis published in Nature Communications. On a large scale, recycling could also help relieve the long-term supply insecurity – physically and geopolitically – of critical battery minerals. Lithium-ion battery recyclers source materials from two main streams: defective scrap material from battery manufacturers, and so-called “dead” batteries, mostly collected from workplaces. The recycling process extracts lithium, nickel,…
