Effectively removing carbon dioxide from the atmosphere
Researchers at the Paul Scherrer Institute PSI and ETH Zurich have investigated the extent to which direct capture of carbon dioxide (CO2) from the ambient air can help to effectively remove greenhouse gasses from the atmosphere. The result: With car.....»»
So what are we to make of the highly ambitious, private Polaris spaceflight?
They flew high, they walked in space, and finally early on Sunday, they landed. Enlarge / Crew Dragon enters Earth's atmosphere on Sunday morning as recovery boats await. (credit: SpaceX) A white spacecraft, lightly toas.....»»
Exploring ternary metal sulfides as electrocatalysts for carbon dioxide reduction reactions
One of the most promising avenues for actively reducing CO2 levels in the atmosphere is recycling it into valuable chemicals via electrocatalytic CO2 reduction reactions. With a suitable electrocatalyst, this can be achieved under mild conditions and.....»»
Urban forests could help reduce heat-related mortality, study suggests
Across the globe, heat waves are becoming more frequent and more intense. Therefore, how to effectively combat the adverse effects of heat is an increasingly important topic of research......»»
Trees in tropical logged forests release carbon at greater rate despite faster growth, study finds
Tree stems in tropical forests recovering from logging produce carbon dioxide at a greater rate than those in unlogged forests, according to a new study from the University of Leicester......»»
Researchers identify novel approach to minimize nitrogen loss in crops
While agriculture producers apply nitrogen fertilizer to supply nutrients to their crops, they can't always keep those nutrients in the soil for maximum efficiency, often losing them into the atmosphere or water supply as nitrates and nitrous oxide......»»
Rapid loss of Antarctic ice after 2100 likely under current emissions, climate scientists find
A Dartmouth-led study by more than 50 climate scientists worldwide provides the first clear projection of how carbon emissions may drive the loss of Antarctica's ice sheet over the next 300 years......»»
Microbe dietary preferences found to influence effectiveness of carbon sequestration in deep ocean
The movement of carbon dioxide (CO2) from the surface of the ocean, where it is in active contact with the atmosphere, to the deep ocean, where it can be sequestered away for decades, centuries, or longer, depends on a number of seemingly small proce.....»»
Development strategies for using carbon-based catalysts in CO₂ conversion
One of the primary drivers of climate change, CO2 emissions, has reached over 35 million tons worldwide. With global annual temperatures still rising, reducing CO2 emissions has become a necessity. To turn this necessity into an opportunity, research.....»»
Personal carbon footprint of the rich is vastly underestimated by rich and poor alike, study finds
The personal carbon footprint of the richest people in society is grossly underestimated, both by the rich themselves and by those on middle and lower incomes, no matter which country they come from. At the same time, both the rich and the poor drast.....»»
Ozone pollution reduces yearly tropical forest growth by 5.1%, study finds
Ozone gas is reducing the growth of tropical forests—leaving an estimated 290 million tonnes of carbon uncaptured each year, new research shows......»»
NASA"s EZIE mission set for 2025 launch
In 2025, NASA will launch its first mission to image the magnetic fingerprint of intense electrical currents that flow high in our atmosphere when auroras shimmer above Earth's poles......»»
A CGE model for provincial analysis of China"s carbon neutrality target
Computable General Equilibrium (CGE) models have become increasingly prevalent, offering valuable insights into the complex and interconnected economic and environmental impacts of climate mitigation strategies. The China Regional Energy Model (C-REM.....»»
NASA scientists recreate Mars"s spider-shaped geologic formations in lab for the first time
Tests on Earth appear to confirm how the red planet's spider-shaped geologic formations are carved by carbon dioxide......»»
Biogeochemistry scientists from around the world publish position paper on tackling "hidden" phosphorus
As the world tries to mitigate agriculture's effect on the environment, much of the story can be found in soil, which stores and cycles nutrient elements of carbon, nitrogen, and phosphorus......»»
The profound impact of COVID-19 on China"s agricultural carbon emissions
As global climate warming becomes increasingly severe, scientists are delving deeper into greenhouse gas emissions across various industries. Recently, a study from Duke Kunshan University and Yangzhou University on the changes in China's agricultura.....»»
Pollution of the potent warming gas methane soars and people are mostly to blame
The amount and proportion of the powerful heat-trapping gas methane that humans spew into the atmosphere is rising, helping to turbocharge climate change, a new study finds......»»
Discovery unveils new path to ethanol production from CO₂
In a study published in Energy & Environmental Science, researchers from the Interface Science Department at the Fritz Haber Institute have introduced a novel method for converting the greenhouse gas carbon dioxide (CO2) into ethanol, a sustainable f.....»»
Unprecedented heat wave on the Tibetan plateau: Study highlights land-atmosphere interactions
Heat waves are generally thought to occur in hot, lowland regions—but what happens when extreme heat strikes the frigid, high-altitude Tibetan Plateau? Is the definition of a heat wave the same at 5,000 meters above sea level as it is in the plains.....»»
Shallow waters make the best carbon sinks, researchers find
Marine phytoplankton take up atmospheric carbon and carry it to the seafloor when they die and sink (a process known as organic carbon sedimentation). This biological carbon pump is a powerful part of Earth's carbon cycle, yet scientists don't have a.....»»
Researchers find live fungi, bacteria and viruses high in the Earth"s atmosphere
A team of climate, health and atmospheric specialists in Spain and Japan has found abundant live fungi, bacteria and viruses high in the Earth's atmosphere. In their study published in the Proceedings of the National Academy of Sciences, the group co.....»»
