Petunia and pansy reactions to prolonged carbon dioxide enrichment
Although crops often respond immediately to enriched CO2 concentrations (e.g., increased photosynthesis), this initial response is often not sustained throughout production, thus reducing the benefit of this input. For horticulture species, the timin.....»»
Scientists develop a phase-transformable membrane for efficient gas separation
Industrial gas separation, essential for clean energy and environmental protection, demands efficiency and adaptability. Current materials, however, lack the flexibility to selectively separate gases like carbon dioxide (CO2) and hydrogen (H2) while.....»»
New platinum-nickel core-shell catalyst shows stability for oxygen reduction reactions
Electrocatalysis is a key technology for sustainable energy, and understanding how catalysts work is crucial for improving their performance. One of the challenges in using platinum (Pt) as a catalyst for the oxygen reduction reaction (ORR) in fuel c.....»»
Stark warning on emissions as leaders split on climate goals at COP29
Global leaders offered competing views on how to tackle climate change at UN-led talks Wednesday as a new report warned the world must reach carbon neutrality much sooner than planned......»»
Nations to submit boosted climate plans: what"s at stake?
Nations have begun setting carbon-cutting targets for the decade ahead, and how ambitious these pledges are could make or break global efforts to avoid dangerous levels of climate change......»»
Nations approve new UN rules on carbon markets at COP29
Governments at the COP29 talks approved Monday new UN standards for international carbon markets in a key step toward allowing countries to trade credits to meet their climate targets......»»
Study reveals why carbon boosts metal nanoparticle catalysts
Precious metals play an important role in the chemical industry as catalysts: With the help of silver, platinum, palladium or other elements, chemical reactions can take place that would otherwise not progress or would only progress at a much lower r.....»»
Private jet carbon emissions soar 46%: Study
The carbon footprint from private jet travel grew 46 percent between 2019 and 2023 and will keep rising unless the ultra-luxury industry is regulated, according to new research published Thursday......»»

Three NASA astronauts whose prolonged space station mission ended with a trip to the hospital last month declined to say Friday which one of them was sick......»»
China passes energy law to "promote carbon neutrality"
China on Friday passed a new energy law to promote carbon neutrality, state media reported, as Beijing moves ahead with its pledge to decarbonize its economy by 2060......»»
Advances in plate tectonics research provide a new view of deep Earth"s carbon emissions
From time to time, when Earth's tectonic plates shift, the planet emits a long, slow belch of carbon dioxide. In a new modeling study published in Geochemistry, Geophysics, Geosystems, R. Dietmar Müller and colleagues show how this gas released from.....»»
Battling air pollution may contribute to climate change by impacting soil carbon storage
Decades-old policies aimed at improving air quality may also be accelerating global climate change, warns a recent study published in the journal Ecology......»»
Calcite: The versatile mineral shaping the future of carbon removal
Found all over the world, calcite is the most stable form of calcium carbonate and is the main mineral found in limestone......»»
Locally optimized urban form can reduce carbon dioxide emissions
Research suggests that urban areas could reduce their carbon dioxide (CO2) emissions by optimizing their urban form. However, the relationship between urban form and emissions is highly context-dependent and generalizations cannot be made......»»
Microbial slime: The ultimate system to understand our planet
Billions of years ago, Earth was home to extreme environments, including intense UV radiation, frequent volcanic eruptions, and very high concentrations of carbon dioxide in the atmosphere. Yet, under these conditions, biofilms formed and within thes.....»»
Direct synthesis method uses recovered carbon dioxide and hydrogen to produce formic acid
With the goal of achieving a carbon-neutral society and eliminating greenhouse gas emissions by 2050, efforts are accelerating to utilize hydrogen as a key energy source. To achieve this goal, the technologies for hydrogen storage, transportation, an.....»»
The frozen carbon of the northern permafrost is on the move—we estimated by how much
Among the most rapidly changing parts of our planet are the coldest landscapes near the top of the globe, just south of the Arctic. This region is warming two to four times faster than the global average......»»
Ensuring a bright future for diamond electronics and sensors by perfecting the growth process
Researchers are developing new ideas about the best ways to make lab-grown diamonds while minimizing other forms of carbon, such as soot. These diamonds aren't destined for rings and necklaces, though. These are the kinds that are needed for the comp.....»»
Study finds 30% of regions worldwide achieve economic growth while reducing carbon emissions
More and more regions around the globe combine economic growth with reducing carbon emissions, researchers from the Potsdam Institute for Climate Impact Research and the University of Potsdam found......»»
Portal to the past: Geologist identifies metamorphic rock as a crucial feature of the ancient Earth"s carbon cycle
If Earth's history were a calendar year, humans would not appear until the last few minutes before midnight on Dec. 31. During the Proterozoic Eon—2.5 billion years to 543 million years ago—the sun was still a young star, much dimmer than today,.....»»
Artificial intelligence: A double-edged sword for the environment?
As AI technology progresses, the energy demands of training complex AI models have surged, raising widespread concerns about associated carbon emissions. This rapid growth is fueled by global demand across industries and academia, leading to exponent.....»»
