When attacks disrupted shipping lanes in the Red Sea, few scientists imagined the effects would reach the clouds over the South Atlantic.

Global shipping rules that quietly cleaned up one of the world’s dirtiest fuels are now reshaping the clouds that hang over ...

A single green laser, a glass bead smaller than a bacterium and a lab in Austria are helping you see lightning in a new way.

A new study suggests that adding a tiny amount of ice-nucleating particles into aircraft engine exhaust could make contrails far less harmful by shortening their lifespan.

The chemical interaction between air pollutants and sea salt particles can have effects on air quality, according to the ...
