Around the globe, hotter temperatures stoked by climate change are increasing the odds of both severe drought and heavier ...

Zare and his colleagues sprayed water vapor into a chamber filled with a mix of gases meant to mimic early Earth's atmosphere ...

Rainfall can disappear for years only to return with a vengeance, as it did in California in 2023, with record-setting rain ...

Dry spring weather is causing plants to use more snowmelt, reducing Colorado River streamflow. This explains why runoff ...

FARGO — Humidity is water vapor, which is a clear gas. If you can see water hanging in the air, it must be made of water droplets or ice crystals and so is not water vapor. Steam or mist is made ...

“We have a water-vapor-based plasma thruster that works at power levels so low, people don’t believe it,” Miles Space CEO Brad Berkson told SpaceNews. During testing conducted in September ...

A new study suggests that the first water molecules in the universe may have formed far earlier than previously assumed ...

New Delhi's air pollution is more severe than previously estimated, with particles absorbing atmospheric water vapor, leading to particulate matter levels across the city being underestimated by ...

Zare’s team demonstrated the existence of micro-lightning, very small electricity discharges that occur between tiny droplets ...

Water may have formed less than 200 million years after the Big Bang, suggesting some conditions for life existed far earlier than previously thought.

A hotter atmosphere sucks up more water vapor from bodies of water and vegetation and soil. Over land, this atmospheric demand and loss of surface moisture leads to longer and more intense ...
