Relevance For The Global Climate
H2 is a trace, secondary greenhouse gas that interferes with the removal of methane. H2 interacts with hydroxyl radicals (•OH), reducing them to H20 (water). •OH radicals that would typically oxidize methane in the following reaction are removed if they first interact with H2 in the atmosphere.
H2 + •OH → •H +H20
CH4 + •OH → CH3 + H2O

Famous quotes containing the words relevance, global and/or climate:
“... whatever men do or know or experience can make sense only to the extent that it can be spoken about. There may be truths beyond speech, and they may be of great relevance to man in the singular, that is, to man in so far as he is not a political being, whatever else he may be. Men in the plural, that is, men in so far as they live and move and act in this world, can experience meaningfulness only because they can talk with and make sense to each other and to themselves.”
—Hannah Arendt (1906–1975)
“Ours is a brand—new world of allatonceness. “Time” has ceased, “space” has vanished. We now live in a global village ... a simultaneous happening.”
—Marshall McLuhan (1911–1980)
“There is much to be said against the climate on the coast of British Columbia and Alaska; yet, I believe that the scenery of one good day will compensate the tourists who will go there in increasing numbers.”
—Franklin D. Roosevelt (1882–1945)
