Methane clathrate (CH 4 ·5.75H 2 O) or (4CH 4 ·23H 2 O), also called methane hydrate, hydromethane, methane ice, fire ice, natural gas hydrate, or gas hydrate, is a solid clathrate compound (more specifically, a clathrate hydrate) in which a large amount of methane is trapped within a crystal structure of water, forming a solid similar to ice.
In 2018, a perspective piece devoted to tipping points in the climate system suggested that the climate change contribution from methane hydrates would be "negligible" by the end of the century, but could amount to 0.4–0.5 °C (0.72–0.90 °F) on the millennial timescales. [6]
This methane release results in a positive climate change feedback (meaning one that amplifies warming), as methane is a powerful greenhouse gas. [87] When permafrost thaws due to global warming, large amounts of organic material can become available for methanogenesis and may therefore be released as methane. [88]
In the fight against climate change, the focus is usually on carbon dioxide, or CO 2 — and for good reason. It’s a greenhouse gas that remains in the atmosphere for years, trapping in heat for ...

Methane clathrate block embedded in the sediment of hydrate ridge, off Oregon, USA. Clathrate hydrates, or gas hydrates, clathrates, or hydrates, are crystalline water-based solids physically resembling ice, in which small non-polar molecules (typically gases) or polar molecules with large hydrophobic moieties are trapped inside "cages" of hydrogen bonded, frozen water molecules.
A controlled study run by Rumin8 and University of New England found an impressive 81% reduction in methane emissions when cattle had access to water troughs treated with the tech company's ...
