claim: Melting permafrost can release not just CO2, but also methane, a much stronger heat-trapping gas.

evidences.article: Permafrost
evidences.evidence: Permafrost and clathrates degrade on warming, and thus, large releases of methane from these sources may arise as a result of global warming.

evidences.evidence: It also contains gas hydrates in places, which are a "potential abundant source of energy" but may also destabilize as subsea permafrost warms and thaws, producing large amounts of methane gas, which is a potent greenhouse gas.

evidences.article: Permafrost
evidences.evidence: The consequence is thawing soil, which may be weaker, and release of methane, which contributes to an increased rate of global warming as part of a feedback loop.

evidences.evidence: When the permafrost melts, it releases carbon in the form of carbon dioxide and methane, both of which are greenhouse gases.
