The biggest uncertainty in climate science is white and fluffy. Clouds reflect sunlight back into space, trap heat and move energy around. Their complexity bedevils the computer models that simulate ...

In October 2008, Chris Bretherton lifted off from the coast of northern Chile in a C-130 turboprop plane. It was too dark to see the sandy hills of the Atacama Desert below, but the darkness suited ...

Earth is reflecting less sunlight, and absorbing more heat, than it did several decades ago. Global warming is advancing faster than climate models predicted, with observed temperatures exceeding ...

Inside a bold — and controversial — effort to cool the water around this beloved ecosystem. An Australian research vessel testing a localized form of climate engineering — artificial modification of ...

The Climate Shift Index (CSI), Climate Central’s daily temperature attribution system, applies the latest peer-reviewed methodology to map the influence of climate change on temperatures across the ...

Editor’s note: This is a first-person account of ongoing research. “Last year we had no snow here,” the hotel desk clerk in Anchorage said. That got my attention, because this is Alaska, after all. We ...

Stratocumulus clouds form large carpets in the sky covering approximately 20% of the earth’s surface. They reflect around 40% of the sun’s radiation back into space. The international research team ...

SALT LAKE CITY (AP) — Two wildfires burning in the western United States — including one that has become a “megafire” on the North Rim of the Grand Canyon — are so hot that they’re spurring the ...
