The page at that link says: « The most effective sink of atmospheric methane is the hydroxyl radical in the troposphere, or the lowest portion of Earth’s atmosphere. As methane rises into the air, it reacts with the hydroxyl radical to create water vapor and carbon dioxide. » So if the page is right, possibly not "most of the ways", but at least "most of the methane".
