(boring not pick, water is not a green house gas as sea level, but in the upper atmosphere water vapour most certainly does help to trap heat in the system - https://science.nasa.gov/earth/climate-change/steamy-relationships-how-atmospheric-water-vapor-amplifies-earths-greenhouse-effect/ https://science.nasa.gov/earth/climate-change/steamy-relatio... This is one of the reasons why methane leaks are so impactful - not only is methane a terrible green house gas, when it decays in the upper atmosphere, it decays into water vapour and CO2)
