Geoengineering our climate system to ward off the effects of global warming may end up cooling the tropics to below present-day levels.

The magnitude of climate change millions of years ago suggests that future temperatures may increase far more than projected.

New research points to more dust particles in the atmosphere than previously believed.

Strong jet streams often plow into the West Coast in wintertime, but the heaviest rains and snows occur when the flow dips far south over the Pacific, allowing it to bring an atmospheric river of warm, moist air from the subtropics to California.

The periodic cooling of the eastern tropical Pacific Ocean helps bring rain to Alaska and blizzards to Colorado.
