By flying over atmospheric rivers, scientists aim to improve forecasts
Drenching atmospheric rivers are slamming the U.S. West Coast, bringing needed water but dangerous flooding. Here’s how scientists study these storms.

Coronal rain has been seen splashing on the sun
New images of the solar corona, taken by the Solar Orbiter probe, reveal bright fireball effects and upwelling induced by falling plasma droplets.

Methane may not warm the Earth quite as much as previously thought
Methane absorbs both longwave and shortwave radiation, with competing effects on climate, a study finds. The gas remains a potent warmer of the planet.

50 years ago, scientists warned of the ‘neglected dangers’ of heat islands
In 1973, scientists knew temperatures in cities were higher than in rural areas. Now, some cities are attempting to cool down with engineering.
