A clathrate is a structure in which a primary molecular species (say water, or H2O) forms a crystalline 'cage' to contain a guest molecule (methane or CH4, for example.
For thousands of years--and, in some cases, about 1,000,000 years--huge caches of methane have lain frozen and isolated from the atmosphere, both in the northern latitude permafrost and in the frozen seafloor methane clathrate deposits, in which gas is trapped in a crystal lattice cage of frozen water.
For example, silver ion-based agents include compounds that contain silver as part of the structure that can be covalently bound, ionically bound or bound by other mechanisms known as "charge-transfer" complexes, including clathrate compounds that involve silver or silver species as part of the structure.

450) Methane hydrates "are ice-like crystalline substances occurring in nature where a solid water lattice accommodates gas molecules (primarily methane, the mqjor component of natural gas) in a cage-like structure, also known as clathrate.
Warming of Arctic waters is causing offshore permafrost to thaw, allowing the clathrate to melt and releasing methane into the water and thence into the atmosphere.
