What is water vapor water vapor is water in its gaseous state-instead of liquid or solid (ice) water vapor is totally invisible if you see a cloud, fog, or mist.
Because water vapor is a greenhouse gas, this results in further warming and so is a positive feedback that amplifies the original warming.
