First, what is an ice age? It’s when the Earth has cold temperatures for a long time – millions to tens of millions of years – that lead to ice sheets and glaciers covering large areas of its surface.

On its own, Earth would shift toward another ice age in about 10,000 years, scientists say. But humanity's greenhouse gas emissions may have radically shifted the climate's trajectory. Credit: Matt ...

Earth's climate has swung between ice ages and warmer periods for millions of years, driven by subtle changes in our planet's ...

A pattern of encroaching and retreating ice sheets during and between ice ages has been shown to match certain orbital parameters of Earth around the sun, leading to researchers being able to predict ...

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 ...

Earth has experienced several climate cycles throughout its long history, including several ice ages that caused the planet to freeze over. The last ice age occurred approximately 11,700 years ago, ...

Imagine Earth covered in thick sheets of ice. And sea levels so low you could walk to a different continent. This is what our ...

A new study published last week is giving us a better idea. The research builds on previous hypotheses theorizing that Ice Ages occur on a predictable timeline that relates to the geometry of Earth’s ...

The Ice Age was a world locked in endless winter, where massive glaciers crept across continents and woolly mammoths roamed ...

A new study highlights the key role the Southern Ocean plays in the Earth’s climate system. Around 12,000 years ago, the last ...
