This type of methane is the primary constituent of natural gas, making up 70 to 90% of it. Propane is a common by-product found in natural gas.Biogenic and thermogenic methane may have different origins but they have the same properties, making them both effective greenhouse gases. ...

"Something is going on in the surface waters and nobody has been paying attention so far," Daniel McGinnis, co-author of the study with his colleague Daphne Donis said, Swiss New Agency ATS reported. Methane is a gas whose greenhouse effect is 28 times greater than that of carbon dioxide...
Cows produce much methane (甲烷), the world’s second worst greenhouse gas, as they break down the grass. They are a large source of the greenhouse gases that are driving climate change. Now scientists have shown the pollution from cows can be reduced by adding a little seaweed (海藻) to...
aMethane gas (甲烷、沼气)in the atmosphere is known as a “greenhouse” gas because it keeps heat just like a greenhouse does, causing our planet to warm up. That’s an environmental concern. But the digester has a good result. Its gas is kept and used to power electric generators (发...
"Methane is the second most important gas after carbon dioxide. It is responsible for a fifth of the enhanced greenhouse effect over the past 200 years," says Dr Paul Fraser, a chief research scientist at CSIRO Atmospheric Research. "Over the past four years there has been no growth in ...
Methane (CH4) is a potent greenhouse gas and its concentrations have tripled in the atmosphere since the industrial revolution. There is evidence that global warming has increased CH4 emissions from freshwater ecosystems1,2, providing positive feedback t
Scientists says the grim milestone underscores the importance of a pledge made at last year’s COP26 climate summit to curb emissions of methane, a greenhouse gas at least 28 times as potent as carbon dioxide.Access options Access Nature and 54 other Nature Portfolio journals Get Nature+, ...
