Greenhouse gas impact of hydroelectric reservoirs downgraded
An international team of scientists has amassed the largest data set to date on greenhouse gas emissions from hydroelectric reservoirs. Their analysis, published today in the online version of Nature Geoscience, po ...
Earthquakes trigger undersea methane reservoirs: study
Earthquakes can rip open sub-sea pockets of methane, a highly potent greenhouse gas, according to a study by German and Swiss scientists published on Sunday.
'Planetary emergency' due to Arctic melt, experts warn
Experts warned of a "planetary emergency" due to the unforeseen global consequences of Arctic ice melt, including methane gas released from permafrost regions currently under ice.
Study: Biodegradable products may be bad for the environment
Research from North Carolina State University shows that so-called biodegradable products are likely doing more harm than good in landfills, because they are releasing a powerful greenhouse gas as they break down.
How dairy farms contribute to greenhouse gas emissions
U.S. Department of Agriculture (USDA) scientists have produced the first detailed data on how large-scale dairy facilities contribute to the emission of greenhouse gases. This research was conducted by Agricultural Research ...
Gaseous emissions from dinosaurs may have warmed prehistoric earth
Sauropod dinosaurs could in principle have produced enough of the greenhouse gas methane to warm the climate many millions of years ago, at a time when the Earth was warm and wet. That's according to calculations ...
Japanese project aims to turn CO2 into natural gas
Japanese researchers said Wednesday they hoped to enlist bacteria in the fight against global warming to transform carbon dioxide buried under the seabed into natural gas.
Engineers use rocket science to make wastewater treatment sustainable
Within the sludge of wastewater treatment plants is an invisible world teeming with microbes. Here, diverse species of bacteria convert solid and liquid wastes into gases, some of which contribute to global ...
Australian scientists aim to reduce sheep burps
Australian scientists are working to breed a sheep that belches less, as they look for ways to reduce harmful methane emissions from the country's woolly flocks, a researcher said Sunday.
15-year study: When it comes to creating wetlands, Mother Nature is in charge
Fifteen years of studying two experimental wetlands has convinced Bill Mitsch that turning the reins over to Mother Nature makes the most sense when it comes to this area of ecological restoration.
America's natural gas system is leaky and in need of a fix, new study finds
The first thorough comparison of evidence for natural gas system leaks confirms that organizations including the Environmental Protection Agency (EPA) have underestimated U.S. methane emissions generally, ...
Satellite observes spatiotemporal variations in mid-upper tropospheric methane over China
As a principal greenhouse gas, atmospheric methane is important to atmospheric chemical processes and climate change. In Vol. 56 of the Chinese Science Bulletin, a paper identified spatiotemporal variations of methane in the ...
Study finds novel worm community affecting methane release in ocean
Scientists have discovered a super-charged methane seep in the ocean off New Zealand that has created its own unique food web, resulting in much more methane escaping from the ocean floor into the water column.
