Methane Emissions from Wetlands Increase Significantly over High Latitudes
Wetlands are Earth’s largest natural source of methane, a potent greenhouse gas that is about 30 times more powerful than carbon dioxide at warming the atmosphere. A research team analyzed wetland methane emissions data across the entire Boreal-Arctic region and found that these emissions have increased approximately nine percent since 2002.
New study reports that Greenland is a methane sink rather than a source
Researchers at the University of Copenhagen have concluded that the methane uptake in dry landscapes exceeds methane emissions from wet areas across the ice-free part of Greenland.
Illinois-led team puts cows and microbes to work to reduce greenhouse gases
With funding from the Foundation for Food and Agriculture Research, University of Illinois faculty, along with an international team of scientists, is recruiting a surprising ally to make a powerful dent in greenhouse gas emissions: the cow. The team will work to re-route hydrogen atoms away from methane during the fermentation process in the rumen, toward more productive end products.
Ponds release more greenhouse gas than they store
Though human-made ponds both sequester and release greenhouse gases, when added up, they may be net emitters, according to two related studies by Cornell University researchers.
‘Red sea plume’ alga may cut greenhouse gas emissions from cow poo nearly in half
Approximately a third of all anthropogenic methane is emitted by ruminant livestock. These animals get nutrients through fermenting food in four-chambered stomachs found in cows, sheep, and goats.
Methane from megafires: more spew than we knew
Using a new detection method, UC Riverside scientists found a massive amount of methane, a super-potent greenhouse gas, coming from wildfires — a source not currently being accounted for by state air quality managers.
Methane breath testing for a better future
A University of Adelaide-led study will investigate if mixing a variety of compounds, including biserrula, into cow feed that contains seaweed, can reduce the amount of methane produced by livestock.
Significant reductions in global greenhouse gas emissions still possible
About a quarter of the world’s electricity currently comes from power plants fired by natural gas. These contribute significantly to global greenhouse gas emissions (amounting to 10% of energy-related emissions according to the most recent figures from 2017) and climate change.
Scientists find iron cycling key to permafrost greenhouse gas emissions
The interaction of elemental iron with the vast stores of carbon locked away in Arctic soils is key to how greenhouse gases are emitted during thawing and should be included in models used to predict Earth’s climate, Oak Ridge National Laboratory scientists found.
Model analysis of atmospheric observations reveals methane leakage in North China
Natural gas is a relatively clean burning fossil fuel, that causes less air pollution than coal and is widely used in the world.
Negligible climatic impact of the recent methane leak from the Nord Stream pipelines
On 26 September 2022, Nord Stream 1 and 2, two subsea pipelines for transferring natural gas from Russia to Germany, were both deliberately ruptured.
New approach improves identification of natural-gas emitters
A new study in New Mexico’s San Juan Basin will boost efforts to identify and reduce methane emissions, a key element of the Global Methane Pledge. The research team found that using multiple methods to measure the ratio of ethane to methane in the ambient air around fossil energy development regions can be used to attribute emissions to specific polluters.
Biogas and biomethane supply chains leak twice as much methane as first thought
Although biogas and biomethane remain climate-friendlier than non-renewable alternatives, the researchers call for better monitoring and fixing of leaks to ensure biogas and biomethane continue to live up to their green credentials.
‘No excuse now’: Biden methane regulation comes tech ready
The Biden administration announced Tuesday that it would limit methane emissions from oil and gas rigs — part of a global effort to cut methane levels at least 30% by 2030. John Albertson is a professor of civil and environmental engineering…
Cornell to build new facility aimed at reducing methane emissions
Four climate-controlled respiration chambers will be built at Cornell University to study gas exchange of dairy cattle and other livestock with the goal of reducing climate-warming methane emissions.
Mapping methane sources in Paris
Researchers reporting in ACS’ Environmental Science & Technology have conducted mobile measurements of methane and its sources throughout Paris. Their findings suggest that the natural gas distribution network, the sewage system and furnaces of buildings are ideal targets for methane reduction efforts.
Mapping intermittent methane emissions across the Permian Basin
Researchers reporting in ACS’ Environmental Science & Technology Letters have conducted an extensive airborne campaign with imaging spectrometers and identified large methane sources across the Permian Basin area.
Methane Emissions from Coal Mines Are Higher Than Previously Thought
Methane emissions from coal mining are likely much higher than previously calculated, according to new research. That’s due mainly to emissions from abandoned mines and higher methane content in deep coal seams.
Science Snapshots from Berkeley Lab
Advanced X-ray techniques yield insights into a bacterial enzyme that turns methane gas into liquid fuel, and a genome resource expands known diversity of bacteria and archaea by 44%
UNH Collaborates with 13 Universities to Understand Climate Change and Ecosystems
The University of New Hampshire is one of 14 universities from around the globe that have collectively been awarded $12.5 million by the National Science Foundation (NSF) to launch a new Biology Integration Institute (BII), called EMERGE, which will focus on better understanding ecosystem and climate interactions—like the thawing of the Arctic permafrost—and how they can alter everything from the landscape to greenhouse gases.
Global Methane Emissions Soaring, But How Much Was Due to Wetlands?
A Q&A with Berkeley Lab scientist William Riley on the challenges in estimating methane emissions from wetlands and how nuanced computer models may help
Containing methane and its contribution to global warming
Methane is a gas that deserves more attention in the climate debate as it contributes to almost half of human-made global warming in the short-term.
