From mangroves to fjords, coastal ecosystems can take up or emit greenhouse gases. But globally, they"re a vital sink
Coastal ecosystems can absorb or emit the three main greenhouse gases: carbon dioxide, methane and nitrous oxide......»»
AI model harnesses physics to autocorrect remote sensing data
Turbulence, temperature changes, water vapor, carbon dioxide, ozone, methane, and other gases absorb, reflect, and scatter sunlight as it passes through the atmosphere, bounces off the Earth's surface, and is collected by a sensor on a remote sensing.....»»
Melting high-mountain glaciers would release greenhouse gases into atmosphere, suggest scientists
The retreat of high mountain glaciers has accelerated since the 1980s, resulting in increased glacier runoff. However, it remains uncertain whether melting mountain glaciers enhance or release greenhouse gases, and whether areas exposed to glacier re.....»»
Methane flux in North Sea varies with tides, study shows
Methane, a strong greenhouse gas that naturally escapes from the bottom of the North Sea, is affected by the pressure of high or low tide. Methane emissions from the sea floor can be just easily three times as much or as little, depending on the tide.....»»
Unprecedented warming threatens Earth"s lakes and their ecosystems
Lakes, with their rich biodiversity and important ecological services, face a concerning trend: rapidly increasing temperatures. A recent study published in Nature Geoscience by an international team of limnologists and climate modelers reveals that.....»»
Study: Targeted home systems to remove PFAS more cost-effective than system-wide solutions
PFAS, the potentially cancer-causing chemicals known as "forever chemicals," have become an increasing concern in home drinking water. Solutions to reduce the risk of exposure range from mandated municipal-level water treatment to under-the-sink home.....»»
Study reveals Australian teachers need more support for well-being at work
A Monash University study has shed light on how Australian teachers conceptualize their well-being at work, offering vital insights that could help shape future policies and interventions aimed at improving the educational environment for teachers na.....»»
Integrating monitoring data to analyze greenhouse gas emissions from reservoirs in the Yellow River Basin
A study published in the journal Science China Earth Sciences integrates existing monitoring data to discuss the characteristics of greenhouse gas (GHG) emissions from reservoirs in the Yellow River Basin. While CO2 emission flux from reservoirs is l.....»»
Archaeologists find ancient temple and theater in Peru
A team of archaeologists, led by Field Museum scientist Luis Muro Ynoñán, has unearthed the remains of what appears to be a four-thousand-year-old temple and theater in coastal Peru......»»
From robots and drones to sheep trackers, new tech can help farmers monitor and improve soil health
Twelve million hectares of agricultural soils are lost globally through soil degradation every year. As an ecologist, I work alongside farmers and growers in the field and have seen how farming can help solve this global soil crisis......»»
Study finds nitrite-driven anaerobic ethane oxidation in microbial cultures
Ethane, an overlooked greenhouse gas, can be oxidized with electron acceptors like sulfate and nitrate. Despite nitrite being a more thermodynamically feasible electron acceptor, little is known about nitrite-driven anaerobic ethane oxidation......»»
Aerosols shown to increase size of cloud cells, causing greater radiative cooling under polluted conditions
Aerosols, often emitted alongside greenhouse gases, can brighten clouds and cause significant cooling. However, the uncertainty associated with aerosol–cloud interactions (ACIs) is large and potentially significant enough to mask a sizable portion.....»»
The art of molecular self-assembly: Crafting 2D nanostructures for advanced materials
Creating periodic nanostructures is vital for progress in material science and nanotechnology. Traditional methods often struggle with complexity and scalability. Integrating bottom-up self-assembly of block molecules with top-down lithography offers.....»»
Sustainability and climate education are "vital for green jobs," say experts
As the new U.K. government begins its stated mission to "rebuild Britain," a group of education and climate experts is calling for sustainability and climate education to be at the heart of its priorities......»»
Q&A: Extreme weather in South Africa is disrupting tourism—research tracks the impact on coastal areas
South Africa has experienced some extreme weather events in recent months. These have included floods and an uncommon tornado in South Africa's KwaZulu-Natal province, floods in the Eastern Cape and mid-latitude cyclones in the Western Cape. Kaitano.....»»
Innovative use of hyperspectral data and DCGANs enhances rice protein content estimation
Rice (Oryza sativa L.) is a crucial crop feeding over half of the global population. The demand for high-quality, protein-rich rice is rising, making accurate grain protein content (GPC) estimation vital for breeding superior varieties......»»
Study projects major changes in North Atlantic and Arctic marine ecosystems due to climate change
New research predicts significant shifts in marine fish communities in the North Atlantic and Arctic Oceans as a result of climate warming......»»
Researchers evaluate impact of warming on soil respiration in different ecosystems
Soil respiration is the result of heterotrophic respiration (Rh) and autotrophic respiration (Ra), accounting for about 50%–75% of the total ecosystem respiration on land, which is crucial for the global carbon cycle and plays an indispensable role.....»»
Study reveals rapid evolution and global spread of Pseudomonas aeruginosa
Pseudomonas aeruginosa—an environmental bacteria that can cause devastating multidrug-resistant infections, particularly in people with underlying lung conditions—evolved rapidly and then spread globally over the last 200 years, probably driven b.....»»
Study claims governments should account for public attitudes before communicating crisis policies
Research published in the International Journal of Knowledge-Based Development has found that our feelings and attitudes during times of crises affect our behavior and that during globally testing times, such as the COVID-19 pandemic, governments sho.....»»
Rising risks of climate disasters mean some communities will need to move—Australians need to plan for relocation
Many Australians live in areas increasingly exposed to climate change and associated extreme weather such as floods, fires, coastal erosion, cyclones and extreme heat. If we wait for disasters to happen, hundreds of thousands of people could be force.....»»
