Explanation:
Statement 1 is correct. Global warming might trigger the release of methane gas from methane hydrate deposits. Methane hydrates are ice-like crystalline structures in which methane gas is trapped. Rising temperatures could destabilize these deposits, leading to the release of methane, which is a potent greenhouse gas.
Statement 2 is correct. Large deposits of methane hydrates are found in Arctic Tundra and under the seafloor. The Arctic region and deep ocean sediments are known to have significant methane hydrate reserves.
Statement 3 is correct. Methane in the atmosphere does not oxidize to carbon dioxide after a decade or two. Methane has a shorter lifespan in the atmosphere and eventually oxidizes to carbon dioxide and water vapor through various processes.
