Water vapor feedback can also amplify the warming effect of other greenhouse gases, such that the warming brought about by increased carbon dioxide allows more water vapor to enter the atmosphere… And since water vapor is itself a greenhouse gas, the increase in humidity amplifies the warming from carbon dioxide."

It’s true that water vapor is the largest contributor to the Earth’s greenhouse effect. On average, it probably accounts for about 60% of the warming effect. However, water vapor does not control the Earth’s temperature, but is instead controlled by the temperature. This is because the temperature of the surrounding atmosphere limits the maximum ...

“Water vapour is the most important greenhouse gas. This is part of the difficulty with the public and the media in understanding that 95% of greenhouse gases are water vapour. The public understand it, in that if you get a fall evening or spring evening and the sky is clear the heat will escape and the temperature will drop and you get frost.

It's true that water vapour is the biggest overall contributor to the greenhouse effect and that humans are not responsible for directly emitting this gas in quantities sufficient to change its...

The most plausible explanation is that it’s due to the human-caused increase in greenhouse gases.” More water vapor – which is itself a greenhouse gas – amplifies the warming effect of increased atmospheric levels of carbon dioxide. This is what scientists call a “positive feedback.” Figure courtesy of Carl Mears and Frank Wentz/

According to the Intergovernmental Panel on Climate Change or IPCC, 36–70% of the greenhouse effect is due to water vapor in the Earth's atmosphere. One important consideration of water as a greenhouse gas is that an increase in the Earth's surface temperature increases the amount of water vapor air can hold, leading to increased warming.

Water vapor is a greenhouse gas, and sustained additional water vapor concentrations (resulting from higher average temperatures) will trap additional heat and result in additional warming. Increasing temperatures also influence cloud formation, though the relationship is complex and humidity is but one of many contributing factors.
