How does water vapor in our atmosphere contribute to global warming?

How does water vapor in our atmosphere contribute to global warming?

Response: Higher concentrations of carbon dioxide and other greenhouse gases (GHGs) in the atmosphere cause the Earth to warm. Warmer temperatures increase the rate of water vapor in the atmosphere. Because water vapor is a GHG this leads to even further warming. In this way, water vapor actually magnifies the warming caused by excess carbon dioxide and other greenhouse gases.1
