Not sure what you mean by this. Are you saying water vapor is not a significant greenhouse gas? https://climate.nasa.gov/causes https://climate.nasa.gov/causes lists it as the most abundant greenhouse gas.
- breakyerself 7y agoIt has a residence time in the atmosphere of 72 hours. Water vapor only works as a feedback. It isn't a prime mover of climate change.
- linuxftw 7y agoThe sun is the prime mover of climate change, literally everything else is feedback. If increased temperature creates increased water vapor, and increased water vapor causes increased solar radiation retention due to greenhouse effect (resulting in further temperature increases), that's a positive feedback cycle. Water vapor is undisputed as the the #1 greenhouse gas.
