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 ...

A seemingly small planetary neighbor may play a larger role in Earth’s climate than previously thought. Mars is only about ...

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 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 ...

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 ...

As the last Ice Age came to an end nearly 10,000 years ago, something unexpected happened deep beneath Earth’s surface. Large glaciers began to melt. The sea levels rose quickly—about 1 centimeter per ...

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 ...

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 ...

Glaciation refers to the climatic and geophysical processes leading to the formation, expansion, and persistence of glaciers and ice sheets, and their subsequent sculpting of the Earth’s surface. It ...
