Methane

Cattle are a major source of greenhouse gas emissions, mainly due to their methane-loaded burps. A detailed new study has found more evidence that feeding cows a small seaweed supplement can greatly reduce their methane emissions.

Scientists at the University of Illinois Chicago have found a catalyst that allows the methane in natural gas to be converted into methanol at room temperature, providing a far less energy-intensive option than current solutions.

Engineers at Penn State University have developed a new type of flexible cement they say can be used to contain methane leaks, by being fed into the the very fine gaps around deteriorating gas wells that traditional cements are unable to fill.

New analysis has revealed that emissions of methane, a particularly potent greenhouse gas, have now hit record highs, with the surge being driven in large part by increases in the burning of fossil fuels and increasing agricultural activity.

As tasty as cows are, their greenhouse gas emissions aren’t quite so palatable. To help clean up the agriculture industry, Burger King has now announced it will start feeding its cows a new diet that can cut methane emissions by as much as a third.

The Arctic permafrost is thawing, which could release huge amounts of greenhouse gases stored there. But now researchers have found that methane-munching microbes might counter some of that, resulting in far lower emissions than previously thought.

NASA has developed a new 3D map to not only keep track of methane sources but follow its movement as it builds up and travels through the atmosphere, offering a new tool in the efforts to mitigate its impacts.

Scientists at Pennsylvania State University have discovered that adding a single supplement to the feed of cows can cut their methane emissions by around 25 percent, without affecting their milk-producing capacity.

A new study suggests we may have been severely underestimating the role of human activity in methane emissions, uncovering evidence that levels of human-caused methane are as much as 40 percent higher than previously estimated.

Researchers from the Skolkovo Institute of Science and Technology (Skoltech) and Heriot-Watt University in Edinburgh are looking at a method of extracting methane from Arctic permafrost, in a way that reduces carbon dioxide emissions.

A new UN report, the Greenhouse Gas Bulletin, says that in 2018, the globally-averaged concentration of carbon dioxide (CO2) in the atmosphere was 407.8 parts per million (ppm), a new record high that hasn’t been seen in millions of years.

In some ways, the most Earth-like world in our solar system is Saturn’s largest moon, Titan. And now, astronomers from NASA JPL and Arizona State University have used years of Cassini data to construct the first global map of Titan.
