One factor that makes Methane not quite as bad as it could be, is it has an atmospheric half-life around 10% of CO2's So if a lot of Methane does get released

So if a lot of Methane does get released into the atmosphere, in a couple of decades most of it will have broken down and disappeared.
- regularfry 12y agoThat doesn't mean that the climate will return to where it was before the release. It could find a new stable point at a higher temperature than it is now due to changes in the Earth's albedo, among other things. Also, "disappeared": what it ends up breaking down into is carbon dioxide and water vapour, both greenhouse gases in their own right.
