Scientists have long debated what causes glacial/interglacial cycles, which have occurred most recently at intervals of about 100,000 years. A new study reported in the March 24 issue of Nature finds ...

Without human-induced climate change, Earth may have been on track to plunge into another ice age within 11,000 years. This long-term forecast of the planet’s “natural” climate is based on a new ...

The ebb and flow of Pleistocene glacial cycles is not random; it follows a predictable pattern dictated by the distinct and deterministic influence of Earth’s orbital geometry, according to a new ...

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 ...

The climate modeling community has been particularly vexed by the glacial/interglacial cycles of the past three million years, when the Northern Hemisphere oscillated between times with and without ...

These ancient cores may contain clues about an unexplained change in Earth’s glacial-interglacial cycles, and could shed light on how human-generated emissions will shape our planet’s future. Reading ...

The cows watched us as we trekked through the tall grass of the Ruataniwha Conservation Park in New Zealand. Tails swished in the warm summer air, and their heads slowly turned in sync to follow our ...

Earth's history is replete with wide-ranging climate changes. Analysis of ice core data from Greenland and Antarctica provide evidence that global temperatures have oscillated no fewer than 20 times ...

Since the arrival of Mars Global Surveyor and more recently Mars Odyssey spacecrafts, a range of facts has revealed the existence of frozen water ice in the top meters of high latitudes near-surface ...
