For more than a quarter billion years, coral reefs did far more than brighten shallow seas. Long before humans appeared, ...

Our planet has experienced dramatic climate shifts throughout its history, oscillating between freezing "icehouse" periods ...

As Earth’s climate changes, one of the hardest things to figure out is exactly how the planet will change in response. And ...

In an exciting development for climate science, researchers have extracted an Arctic ice core containing an astonishing 1.2 million years of Earth’s climate history. The discovery, reported by the ...

This doesn’t mean Mars causes ice ages on its own. Orbital cycles are only part of the picture. Earth’s oceans, atmosphere, ...

Paul Wilcox descends into Devil’s Canopy Cave on Prince of Wales Island. An unlikely discovery in a cave on Prince of Wales Island could help scientists understand Earth’s climate history. A small ...

Coccolithophores, tiny planktonic architects of Earth’s climate, capture carbon, produce oxygen, and leave behind geological records that chronicle our planet’s history. European scientists are ...

Tree rings hold clues about ancient solar storms. New research shows tree growth and carbon storage can shift those signals across years.

Abrupt climate shifts are well documented in Earth's history and are commonly associated with ice-sheet dynamics during past ice ages. However, how similar millennial-scale climate variability could ...

As Earth’s climate continues to shift, scientists are looking to the deep past to understand how the atmosphere has changed over time. By measuring the isotope fingerprints in these microscopic space ...

Earth’s atmosphere is slowly leaking into space, and new research shows some of it reaches the Moon, where it may be ...
