Researchers are developing a radical system that uses chlorine atoms to hunt down and defuse planet-warming methane in animal barns. If the setup proves scalable, it could greatly reduce methane ...

In a spectacular new study, researchers have used light and chlorine to eradicate low-concentration methane from air. The result gets us closer to being able to remove greenhouse gases from livestock ...

The National Academies of Sciences, Engineering and Medicine this week looked at the possibilities of removing methane emissions directly from the air. Removing carbon dioxide from the atmosphere is ...

Methane is the second biggest greenhouse gas contributor to climate change. It’s also 84 times more potent than culprit number one, carbon dioxide. Unsurprisingly, 60% of global emissions result from ...

They’ve been called “bubble chasers,” and “seep seekers,” though they sometimes call themselves “flare hunters.” They’re a ...

Decades of buried trash is releasing methane, a powerful greenhouse gas, at higher rates than previously estimated, the researchers said. By Hiroko Tabuchi They’re vast expanses that can be as big as ...
