Scientists used buckets to scoop out methane bubbles from a spot in the Arctic sea.
Workers and residents near fracking sites in Colorado are exposed to toxic chemicals says a Colorado study.
The researchers were able to scoop the bubbling water out of the sea with buckets.
The 'abiotic' methane may hold clues about its presence elsewhere in the solar system, researchers say.
"The commercialization of shale gas and oil in the 21st century has dramatically increased global methane emissions", said the scientist behind the study.
Scientists have identified genetically inherited gut microbes that regulate how much methane a cow produces.
If growth continues, it could negate or reverse any gains made by reducing carbon dioxide emissions.
"The technology has major environmental ramifications and has the potential to alter the economic and political landscape in many U.S. states."
Four million people living in the Arctic permafrost area will be affected by damage to infrastructure.
The permafrost beneath certain lakes is thawing rapidly, which will release a significant amount of methane into the atmosphere.
Georgian Prime Minister Mamuka Bakhtadze declared a day of mourning and said it was time the government stopped putting its citizens' lives at risk.
The rover has discovered ancient organic material that may be biological in origin, although this has not yet been proven.
If the Arctic permafrost melts, greenhouse gasses equivalent to burning all of the world's forests two-and-a-half times over could be released.
Enceladus is a "hot spot" in the search for extraterrestrial life.
The bacteria, found in a subglacial lake, could be helping to limit the emission of methane into the atmosphere.
Robust model shows for every one degree Celsius warming, 4 million square kilometers would be lost.
It's a vicious cycle: As the weather warms, the Earth's permafrost is melting, releasing greenhouse gases that are going to make the planet even hotter.
The greenhouse gas, the main component of natural gas, had previously been unregulated.
The Interior department's proposal would require oil and gas producers to use technology to limit flaring at oil wells.
To keep global temperatures from rising, we must cut down on animal agriculture.
