For years, scientists have experimented with engineering techniques that can safely modify rainfall. But experts say the ...

Wildfires have spread across the planet for millennia, but they are increasing as the climate warms. Decimated forests, ...

In the late 2010s, when Assistant Professor Flavio Lehner worked for the National Center for Atmospheric Research in Boulder, ...

Putting aerosols in the stratosphere to reflect sunlight could prevent the shutdown of key ocean currents, but only if it is ...

Light-absorbing brown carbon aerosols, emitted by wildfires, remain longer in the atmosphere than expected, which could have implications for climate predictions.

Clouds play an important role in regulating the climate. Bright ones at low altitudes generally reflect solar energy away, ...

The combined effects of climate change and air pollution have led to direct declines in precipitation in the U.S. Southwest, ...

Injecting aerosols into the atmosphere – but at higher altitudes than planes can reach – could cool the climate while ...

Climate scientists say this will help them better understand how changing levels of different atmospheric aerosols impact the planet's energy balance and global temperature trends.

Sea spray aerosols, which form when ocean waves fling particles into the atmosphere, can impact climate in a variety of ways. But their small size and chemical complexity make them hard to study or ...

Kimberly Prather, an atmospheric chemist at UC San Diego, is one of 20 scientists being honored by the National Academy of Sciences for extraordinary achievements, it was announced Monday.
