1) Warming seas or permafrost thaw can destabilise methane hydrate (‘fire-ice’) and release methane, a potent greenhouse gas. 2) Vast reserves occur beneath Arctic tundra and continental-slope sediments under the seafloor. 3) Atmospheric methane oxidises to CO₂ within about 10 years, so its climatic impact is short-lived relative to CO₂. Hence all three statements are correct. ([drishtiias.com](https://www.drishtiias.com/prelims-analysis/2019-prelims-analysis))
