As the world gets hotter, the permafrost melts faster – releasing ever-greater quantities of this dangerous greenhouse gas ... I learned a lot about methane bubbles. narrator: The ice traps ...

On the Gulf of Mexico? The deadly blowout of an oil rig in the Gulf of Mexico was triggered by a bubble of methane gas that escaped from the well and shot up the drill column, expanding quickly as ...

"Methane, which is produced by the fermentation of biomass, has a close cousin, the marsh gas, which sometimes bubbles up and ...

The flames confirm that the bubbles are methane, the main component of natural gas. By counting and measuring them, Walter Anthony is trying to gauge how much methane is rising from Goldstream ...

The methane—normally frozen at great pressure as gas hydrates embedded within subterranean rock—can become dislodged and transform into gaseous bubbles expanding geometrically as they explode ...

These aren't your average lakes. They're called thermokarst lakes and they're filled with highly flammable methane gas. During the summer the gas bubbles to the surface and enters the atmosphere.
