Researchers at Politecnico di Milano's LCCP have developed a process to transform CO₂ into methane using carefully engineered nickel nanoparticles. The study investigates how the size and shape of nickel nanoparticles influence the rate of carbon dioxide conversion into methane.
A new open-source tool, greenfeedr, is introduced to simplify the process of analyzing GreenFeed data from livestock. The R package offers functions for downloading, processing, and generating reports, allowing researchers and producers to automate routine tasks and gain insights into methane and carbon dioxide emissions.
Researchers discovered that Arctic glaciers are leaking significant amounts of methane through the 'glacial fracking' process. This previously unrecognised process could contribute to Arctic climate feedbacks and accelerate global warming.
A new study suggests that increased wildfire activity was a feature of past periods of abrupt climate change, which also saw significant shifts in tropical rainfall patterns and temperature fluctuations. The research analyzed ancient methane trapped in Antarctic ice and found that the spikes were likely caused by global wildfires.
A new analysis reveals that increased inundation and water storage in wetlands drove the record surge in atmospheric methane emissions from 2020 to 2022. Wetland microbes produce methane as they metabolize organic matter anaerobically, leading to a significant increase in release to the atmosphere.
A new study found that tree bark surfaces absorb methane gas from the atmosphere, making trees 10% more beneficial for climate than previously thought. This discovery adds a new layer of importance to tree planting and reducing deforestation as part of efforts to cut methane emissions.
A new study led by Harvard researchers found that the EPA underestimates methane emissions from landfills and urban areas, with emissions being on median 77% higher than estimated. The team's high-resolution map of methane emissions highlights the importance of pinpointing sources of these emissions.
A new study from the University of Copenhagen reveals that Greenland consumes more methane than it releases, with dry landscapes absorbing over 65,000 tons annually. The study's findings contribute significantly to climate models and provide insights into the optimal soil conditions for methane uptake in the Arctic.
A new study published in Geophysical Research Letters sheds light on methane emissions from Arctic lakes and wetlands. Researchers found that small, unmapped lakes contribute only about 3% of the region's methane emissions, significantly reducing the cumulative amount previously thought to be emitted.
A new study found that Sahara dust can enhance the removal of methane from the atmosphere through a photocatalytic reaction. The reaction involves the activation of mineral dust and sea spray aerosols in the presence of sunlight, producing chlorine atoms that oxidize atmospheric methane and tropospheric ozone.
Carreon is developing technology to capture and convert greenhouse gases into clean-burning fuels using reactors powered by renewable energy sources. Her $538,659 NSF award will support this research over five years.
The project, STEAM TANKS, aims to measure methane and other volatile organic compounds emitted from liquid storage tanks in West Virginia, Pennsylvania, and Ohio. The researchers will use mobile laboratories, machine learning methods, and partner with industry leaders to develop solutions to mitigate methane emissions.
Researchers from Princeton University found that hydrogen emissions can lead to an increase in atmospheric methane, canceling out climate benefits. They identified thresholds for managing hydrogen emissions to avoid this consequence.
A study using GOSAT observations and surface station data estimates CH4 emissions from natural gas in the NE region, showing a significant increase trend. The model-estimated total CH4 emissions and natural gas leaks constitute a waste of energy and value.
A recent NTU Singapore study finds that climate change is a stronger driver of increasing atmospheric methane than expected, leading to more heat being trapped in the atmosphere. The research suggests that nature could be producing more and consuming less methane than previously realized, contributing to higher methane emissions.
A recent study reveals that tropical terrestrial methane emissions account for over 80% of the observed changes in global atmospheric methane growth rate between 2010 and 2019. This finding underscores the significant impact of methane on climate change, with methane concentrations more than doubling since the pre-industrial era.
A new study finds that immediate action to reduce methane emissions could preserve Arctic summer sea ice through 2100, with drastic cuts in CO2 also necessary. The chances of saving summer sea ice increase from nearly zero without action to over 80% if net zero CO2 emissions are reached by 2050.
Researchers have found that special treatment of minerals called zeolites can efficiently remove methane from the air, with advantages over other methods. The process converts methane into carbon dioxide, which is less impactful in the atmosphere than methane.
A new study confirms that emissions from anthropogenic sources, including agriculture, landfill/waste, and fossil fuel industry, are the driver for the renewed rise of potent greenhouse gas since 2007. Global wetlands play a minor role with less than 20% contribution to atmospheric methane.
