While the Milankovitch Cycles operate on timescales far longer than human lifespans, their effects are always at play.

Ancient horsetail plants produce water with unusual oxygen isotopes, offering scientists a new tool to reconstruct Earth’s climate history and understand humidity patterns from millions of years ago.

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 ...

Earth’s path around the Sun is not a fixed racetrack but a slowly shifting orbit, and those subtle changes have a long history of reshaping the planet’s climate. As astronomers refine how these ...

Past and future trends in global mean temperature spanning the last 67 million years. Oxygen isotope values in deep-sea benthic foraminifera from sediment cores are a measure of global temperature and ...

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 ...

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 ...

At the edge of East Antarctica, where the wind howls through a white emptiness and the air bites harder than steel, scientists uncovered something so old it makes even time feel young. Beneath that ...

After years as a professional research assistant at INSTAAR’s stable isotope lab, Valerie Morris estimates she’s processed more than 10 kilometers of ice from around the world. “You’ve done more ice ...

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 ...

How did ancient extinction events contribute to global climate change? This is what a recent study published in Nature Communications hopes to address as a team of scientists investigated a connection ...
