According to the National Oceanic and Atmospheric Administration (NOAA), water vapor is the most abundant greenhouse gas and is responsible for about half of Earth's natural greenhouse effect.

NOAA scientists are studying a method that could remove water vapor from Earth's atmosphere before it reaches the stratosphere, reducing one of the greenhouse gases that contributes to global warming.

Carbon dioxide emissions caused by human activity " are by far the most important driver of climate change ", researchers say, but water vapor is the most abundant greenhouse gas and is responsible for about half of Earth's natural greenhouse effect. But it also helps make our planet habitable. (ELISABETTA BONORA, more at aliveuniverse.today)
