Water vapor is a greenhouse gas. Why is it not a concern regarding climate change?

Question

Quizplus · Accepted Answer

Water vapor acts as a feedback rather than a forcing to climate change. The amount of water vapor the atmosphere can hold depends on its temperature. As the Earth warms due to other greenhouse gases like CO2, the atmosphere can hold more water vapor, which in turn can lead to more warming. However, this process is self-regulating through precipitation, which balances the amount of water vapor in the atmosphere, preventing it from independently driving climate change to the same extent as other greenhouse gases.
