Methane

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.

The burning of agricultural waste and the methane that's burped up by cows are two major sources of greenhouse gases. An experimental new type of animal feed, however, is aimed at reducing both the burning and the burps.

A Russian expedition through the East Siberian Sea has uncovered fountains of methane bubbles in concentrations never seen before.

The belches of cattle around the world are a huge source of methane emissions, but a sprinkling of seaweed in their diets could change that.

Livestock like sheep and cows are responsible for huge amounts of methane emissions. Now, an international team of researchers has analyzed the gut microbes of different sheep and found clues that may help us curb the problem.

With oceans of liquid methane, Saturn’s moon Titan is one of the most fascinating places in the solar system. To better understand this weird world, scientists recreated Titan’s alien oceans in the lab, producing new types of crystals that don’t occur naturally on Earth but may be common on Titan.
