An update of charts that gives estimations of the water content of sour natural gas, published 10 years ago, reflects new experimental data and are more accurate for low pressures.

The James Webb Space Telescope (JWST) has detected water vapor near a planet in another system, which could mark the first direct detection of a rocky exoplanet’s atmosphere. But there’s a big ...

Tonga's Hunga Tonga-Hunga Ha'apai volcano spewed an unprecedented amount of water vapor into the atmosphere.

CO2 and other human-generated greenhouse gases are changing Earth's climate despite there being more water vapor in the atmosphere ...

Water vapor has been found in the atmosphere of a distant planet that’s just over twice the size of Earth. It’s the smallest world yet found with water in its surrounding atmosphere, and it ...

Scientists have detected water vapor in the atmosphere of K2-18 b, a potentially habitable alien world about twice the size of Earth. The finding, announced today (Sept. 11), follows a separate ...

The fact that water vapor is the dominant absorber in the Earth's greenhouse effect can lead to a flawed narrative that anthropogenic carbon dioxide (CO2) is not important nor a significant driver ...

The Hunga eruption contributed about 150 metric megatons of water vapor into the stratosphere — an amount so high that it raised global levels of stratospheric water vapor by about 10%.

You may have noticed that humidity (the amount of water vapor in the air) makes a difference in how comfortable you feel outside. When the humidity is high in the summer we say it is "muggy." When ...

Recent water vapor charts (sometimes called our “moisture maps”) show a broad spin that extends across the northwestern Bahamas.

Notice on the “moisture map” (the water vapor chart) areas of green indicate a large swath of moist air that’s bringing rain to many areas.
