As rivers run dry in the Rocky Mountains and the West, it’s easy to wonder where all the snow you see on mountain peaks goes. Some of it ends up in the air, but researchers aren’t sure how much.
Is it time to take drastic steps to modify Earth’s climate to avoid catastrophic warming? A panel of experts says the idea deserves study.

When planes fly from east to west, they are flying against a river of air called a jet stream. These air currents can make your flight longer or shorter, depending on which way you are going.
Thousands of chemical compounds in wildfire smoke are interacting with each other and sunlight as the smoke travels. For people downwind, it can become more toxic over time.

Molina, who died on Oct. 8, ‘thought climate change was the biggest problem in the world long before most people did.’ His research on man-made depletion of the ozone layer won the 1995 Nobel Prize.

From June through October, it’s not unusual for huge Saharan dust plumes to blow across the Atlantic. They can darken skies but also bring calmer weather and electric sunsets. Here’s how they form.
Not all clouds are the same, and climate models have been predicting the wrong kinds of clouds over the Southern Ocean.

Climate models have been overestimating how much sunlight hits the Southern Ocean. This is because the clouds there are different from clouds anywhere else. Bacterial DNA helped us understand why.

Earth’s biggest rivers are streams of warm water vapor in the atmosphere that can cause huge rain and snowfall over land. Climate change is making them longer, wetter and stronger.
