Water vapor is the gaseous state of water. Water vapor is most commonly the result of water evaporation, in which water changes from a liquid to gaseous state, as well as, less commonly, by means of sublimation, which is a change from solid to gaseous.
Water vapor feedback was considered central to the whole global warming issue from the very beginning.[1]
