Water vapour — water in its gas form — is a natural greenhouse gas that traps heat, just like carbon dioxide from burning coal, oil and gas. So, researchers at the National Oceanic and Atmospheric Administration and NASA figure if they can just inject ice high up in the air, water vapour in the upper atmosphere would get a bit drier and that could counteract a small amount of the human-caused warmth. It's just the spark of an initial idea, said the lead author of a study in…

New research has identified oceanic transform faults as significant, previously underestimated sinks for CO2, challenging existing notions about the Earth’s geological carbon cycle. This research emphasizes the crucial role of natural geological emissions in shaping Earth’s climate history and highlights the need for a deeper understanding of these processes in the context of addressing contemporary climate change.

Paint might not seem like the heaviest component to consider when building a large device like an airplane, but its mass can add up. Now, a new and lightweight substance could provide a welcome substitute: Two material scientists from Kobe University, Fujii Minoru and Sugimoto Hiroshi, have discovered nanospheres that are near-invisible silicone crystals. The particles can reflect light thanks to very large and efficient scattering, research published in the journal of ACS Applied Nano Matter details. The result could…

New research identifies vanadium as a promising element for carbon capture, thanks to its balanced reactivity and the ability of vanadium peroxide molecules to bind carbon dioxide efficiently. This work contributes to the global effort to develop direct air capture technologies, offering a new avenue for reducing atmospheric carbon dioxide and mitigating climate change.A chemical element so visually striking that it was named for a goddess shows a “Goldilocks” level of reactivity – neither too much nor too little – that…

Research from Radboud University reveals that peatlands, crucial in carbon storage and combating climate change, are highly susceptible to droughts. Increased biodiversity offers little improvement in drought resilience, highlighting the need for new strategies and political intervention to protect these vital ecosystems.Peatlands experience greater impacts from drought than previously anticipated, raising concerns due to their crucial role in combating climate change. Prolonged drought conditions significantly reduce the…

In the new process, air is channeled through a liquid to capture CO2. If the liquid is irradiated with light, the greenhouse gas is released again and can be collected. Credit:ETH ZurichTo mitigate global warming, significant cuts in greenhouse gas emissions are essential. This includes phasing out fossil fuels and embracing energy-efficient technologies.However, simply cutting emissions is insufficient to achieve climate goals. It’s also critical to remove substantial amounts of CO2 from the atmosphere, storing it…

A new study shows that climate change is disproportionately affecting U.S. forests, particularly in the West, where adverse effects like reduced tree growth are prominent. This trend challenges the forests’ role as carbon sinks and highlights the urgent need for greenhouse gas emission reductions and forest conservation. Credit: SciTechDaily.comClimate change is impacting U.S. forests, especially in the Western regions, leading to decreased tree growth and challenging their ability to act as carbon sinks.Climate change is…

The latest Global Carbon Project report reveals that global CO2 emissions, hitting a record 36.8 billion metric tons in 2023, are far from the reductions required for meeting the Paris Agreement climate goals. Significant disparities in regional trends and the pressing need for increased emissions reduction efforts and carbon removal technologies are highlighted.The latest carbon budget report from the Global Carbon Project reveals that global CO2 emissions remain significantly higher than the reductions required to…
