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.

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

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 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 ...

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 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, ...

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 ...

Scientists trace ancient deep-sea changes in the Southern Ocean to explain how rising CO₂ helped warm Earth after the last ...

If you’ve seen any of the “Ice Age” animated Disney movies, we have some bad news: You don’t know the real ice age.

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 climates trajectory. (Santa Barbara, ...
