This methane is escaping into the atmosphere at a rate that would be dangerous if it continued for a million years or so

but doesn't that depend on the rate at which methane is removed from the atmopshere?

I really don't know. I haven't looked into this much other than reading about it once. I can only gather from this that methane is slowly building up in the atmosphere at a rate greater than the other gases to the point where it become toxic to us. Maybe our bodies will adapt and it won't bother us except when we try light up a smoke. Does it escape the atmosphere, or combine with other gasses and become something else? I thought only hydrogen was light enough to escape the earths gravity.
