atmospheric science

We might have a past faint sun to owe for life’s existence. This has consequences for the possibility of life outside Earth.

Scientists have never been able to adequately explain where lightning comes from. Now the first detailed observations of its emergence inside a cloud have exposed how electric fields grow strong enough to let bolts fly.

After the ultra-powerful James Webb Space Telescope launches later this year, Laura Kreidberg will lead two efforts to check the weather on rocky planets orbiting other stars.

An overlooked but powerful driver of cloud formation could accelerate the loss of polar sea ice.

An 18th-century physicist first predicted the existence of a chorus of atmospheric waves that swoop around Earth. Scientists have finally found them.

Earth’s climate has fluctuated through deep time, pushed by these 10 different causes. Here’s how each compares with modern climate change.

Summer sea ice could vanish later this decade, with disastrous consequences. It all depends on the physics of ice.

Astronomers will soon take their first glance at the atmosphere of a distant exoplanet. Sarah Hörst is writing the guidebook for these exoplanetary explorers, one that will reveal what a distinctive atmosphere says about the world underneath.

A state-of-the-art supercomputer simulation indicates that a feedback loop between global warming and cloud loss can push Earth’s climate past a disastrous tipping point in as little as a century.
