Do volcanoes add more carbon than they take away?
In a new study published in the Journal of Geophysical Research: Biogeosciences, Zhong and colleagues discovered that a volcano in northeast China emits a small net amount of carbon each year. Over geological timescales, that could have a significant.....»»
Catalyst combines vanadium-based components and nitrogen-doped biomass carbon for pollutant removal
Polychlorinated dibenzo-p-dioxins and dibenzofurans are dangerous pollutants due to their carcinogenicity and persistence in the environment. Traditional catalytic oxidation methods for their removal face challenges like high cost and inefficiency at.....»»
Engines that suck carbon from the air are Toyota’s new EV alternative
Toyota is doubling down on internal combustion by testing technology that sucks carbon dioxide out of the atmosphere as the car drives......»»
Toyota working on carbon capture tech for carbon-negative engines
Toyota is doubling down on internal combustion by testing technology that sucks carbon dioxide out of the atmosphere as the car drives......»»
Powering nitrogenases: Researchers find new targets for improving biocatalysts
Nitrogenases are considered promising candidates for the sustainable enzymatic production of ammonia and carbon compounds. Unfortunately, one bottleneck in this complex process, the supply of electrons to the enzymes, has remained a mystery until now.....»»
Ditching meat could release vital land to produce energy and remove carbon from the atmosphere—new study
A radical reduction in the amount of meat, dairy and other products sourced from animals is possible in the coming decades, as people turn to an increasing variety of alternatives. This would unlock vast amounts of land currently used to rear animals.....»»
Side-effects of expanding forests could limit their potential to tackle climate change—new study
Tackling climate change by planting trees has an intuitive appeal. They absorb the greenhouse gas carbon dioxide from the atmosphere without using expensive technology......»»
Assessing soil carbon stocks accurately
Researchers from Teagasc have published an article in Geoderma Regional highlighting the consequences of not measuring soil organic carbon (SOC) stocks in Irish grassland soils precisely. Quantifying changes in SOC, either carbon sequestration or los.....»»
Satellites increasingly critical for monitoring ocean health
Playing a huge role in moderating the climate, oceans are fundamental to the functioning of our planet. Understanding more about how seawater temperatures are rising and how oceans are absorbing excess atmospheric carbon dioxide, as well as knock-on.....»»
Research on the Tirlán grain pool shows the carbon footprint is one of lowest in the world
New research from Teagasc on the Tirlán grain pool shows that Irish grain has one of the lowest carbon footprints in the world. The research, unveiled at the Tirlán Quality Grain Awards this week, is the first of its kind using a Life Cycle Assessm.....»»
Irrecoverable carbon in the mountains: Embracing the opportunity of agroforestry
Over 29% of global irrecoverable carbon, which once gone is not likely to recover in any reasonable timeframe according to scientific literature, is stored in mountains. This biomass, representing irreplaceable ecosystems, biodiversity, and globally.....»»
Black carbon sensor could fill massive monitoring gaps
Black carbon is the most dangerous air pollutant you've never heard of. Its two main sources, diesel exhaust and wood smoke from wildfires and household heating, produce ultrafine air particles that are up to 25 times more of a health hazard per unit.....»»
Side effects of wide scale forestation could reduce carbon removal benefits by up to a third, study finds
Research, led by scientists at the University of Sheffield and published in the journal Science, provides a new insight into the broader impacts of forestation on the Earth's climate, indicating that its positive impact is potentially smaller than pr.....»»
China may miss all key climate targets for 2025: report
China may miss all of its main climate goals for 2025, a new report showed Thursday, as the world's largest emitter increased its reliance on carbon-intensive industries to bolster a flagging economy......»»
Research shows how air pollution has offset expected increases in rainfall
We know that greenhouse gas emissions like carbon dioxide should increase rainfall. The emissions heat the atmosphere, causing a one-two punch: Warmer oceans make it easier for water to evaporate, and warmer air can hold more water vapor, meaning mor.....»»
Carbon emissions from the destruction of mangrove forests predicted to increase by 50,000% by the end of the century
The annual rate of carbon emissions due to the degradation of carbon stocks in mangrove forests is predicted to rise by nearly 50,000% by the end of the century, according to a new study published in Environmental Research Letters. Mangroves in regio.....»»
Quality scores for forestry carbon credit types reveal complex landscape of integrity risks, transparency issues
The Carbon Credit Quality Initiative (CCQI) released new scores for two types of forestry carbon credits: improved forest management (IFM) and commercial afforestation. Together, these project types comprise approximately 10% of recent credit issuanc.....»»
New approach to carbon-14 dating corrects the age of a prehistoric burial site
How old are these bones? This standard question in archaeology can be answered quite precisely in many cases with the help of the carbon isotope 14C. But there are exceptions. Certain living habits, such as that of prehistoric hunter-gatherer-fisher.....»»
Study: Replacing plastics with biodegradable alternatives would lead to significant carbon emissions reduction
Plastic pollution and its impact on the environment have become critical global issues in recent years. In response, the research teams have conducted a study to evaluate the carbon emissions associated with both traditional plastic products and biod.....»»
A botanical Pompeii: Researchers find spectacular Australian plant fossils from 30 million years ago
The Australian continent is now geologically stable. But volcanic rocks, lava flows and a contemporary landscape dotted with extinct volcanoes show this wasn't always the case......»»
Potato plant radiation sensors could one day monitor radiation in areas surrounding power plants
While expanding nuclear energy production would provide carbon-free power and can help countries around the world meet their climate goals, nuclear energy could also come with some inherent risk. Radioactive pollution damages the environment, and it'.....»»
