Trapping gases better with boron nitride "nanopores"
What is common between a technology for storing energy in a solar cell and that for water purification? They both rely on the use of porous materials, or more specifically, 'nanoporous' materials that can trap gas molecules within narrow spaces on th.....»»
Novel technique developed to produce hydrogen peroxide without emitting carbon dioxide
A study published in ACS Applied Materials & Interfaces describes a novel method of producing hydrogen peroxide (H2O2) without emitting carbon dioxide (CO2), one of the main greenhouse gases and one of the world's most widely produced chemicals......»»
Researchers measure boron flux in high-energy cosmic rays with the CALorimetric Electron Telescope (CALET)
Cosmic rays (CR) constitute high-energy particles that mainly originate outside our solar system. These primary CR interact with interstellar matter to produce secondary CR. The secondary nature of their origin is reflected in the higher abundance of.....»»
Viewpoint: The world"s carbon price is a fraction of what we need, because only a fifth of global emissions are priced
At the end of last year, the world's average price to emit one ton of greenhouse gases was around US$5.29 (AU$7.77). For pricing to work as we want—to wean us off fossil fuels—it needs to be around $75 by the end of the decade, according to the I.....»»
This 32,000-mile Ocean Race has yachts doing research along the way

Angola"s peatlands trap carbon and clean the region"s water—how we mapped this newly-found landscape
Ask most people what they picture when thinking about natural "carbon sinks"—ecosystems that absorb and store greenhouse gases—and they'll probably describe a forest. Reforestation is a common feature of climate change plans......»»
Increased atmospheric dust is masking greenhouse gases" warming effect, finds study
A new study shows that global atmospheric dust—microscopic airborne particles from desert dust storms—has a slight overall cooling effect on the planet that has hidden the full amount of warming caused by greenhouse gases......»»

Greenhouse gas concentrations further increased in 2022, finds analysis of global satellite data
Preliminary analyses of global satellite data by environmental researchers at the University of Bremen show that atmospheric concentrations of the two important greenhouse gases carbon dioxide (CO2) and methane (CH4) continued to rise sharply in 2022.....»»
Mapping out key sources of emissions for climate change mitigation
Different regions of the world and different sectors of activity emit various amounts of greenhouse gases and other air pollutants affecting climate change. Knowing the details of these contributions can help policymakers decide where to focus their.....»»

New spectroscopy technique improves trace element detection in liquid
Laser-induced breakdown spectroscopy (LIBS) is a rapid chemical analysis technology that has been well developed for trace element analyses in gases, liquids, and solids. It uses a high-power laser pulse to elicit short-lived, high-temperature plasma.....»»
Methane emissions offset carbon uptake in Baltic macroalgae habitats
Bladderwrack in the Baltic Sea emits significant amounts of methane, which, to some extent, can offset the uptake of atmospheric carbon dioxide by these algae. This is shown by a new study from Askö Laboratory, where the fluxes of greenhouse gases b.....»»

GM recalls 140,000 Chevrolet Bolt EVs over fire risks
GM said the recall covers various 2017 through 2023 model year Chevrolet Bolts due to rare instances of front seat belt pretensioner exhaust gases coming in contact with floor carpeting fibers after a vehicle crash......»»
Carbon dioxide removal should receive additional financial support, says study
Cleaning up greenhouse gases after they have been emitted should be incentivized by subsidies. New evidence from an economic analysis considering international markets suggests an important reason why subsidies should be higher than the price put on.....»»
Researchers analyze volcanic gases with the help of ultra-lightweight sensor systems
The main gases released by volcanoes are water vapor, carbon dioxide, and sulfur dioxide. Analyzing these gases is one of the best ways of obtaining information on volcanic systems and the magmatic processes that are underway. The ratio of carbon dio.....»»
