Terrence Aym's ridiculous claim that the Deepwater Horizon rig would release a "twenty-mile-wide" doomsday "mega-bubble" of this gas was based on Gregory Ryskin's hypothesis that its release from oceanic clathrate hydrates caused a mass extinction during the Paleocene-Eocene Thermal Maximum.
Eruptions of mud volcanoes are almost always accompanied by release of this gas. Plants that live in anoxic soils have developed aerenchyma to transport this gas from the soil to the atmosphere.

In the stratosphere, this gas is broken down in a radical reaction that converts chlorine gas to gaseous hydrogen chloride, while in the troposphere, it is consumed by reacting with a hydroxyl radical. For 10 points, name this greenhouse gas, a simple hydrocarbon that is the main component in natural gas.
