Scientists have uncovered a missing feedback in Earth’s carbon cycle that could cause global warming to overshoot into an ice ...

Global warming may overshoot, driving extreme cooling and potentially triggering Earth’s next ice age, scientists warn.

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 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 ...

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, ...

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.

Changes in Earth's tilt relative to the sun have governed the movements of giant ice sheets over the past 800,000 years, triggering the start and end of eight ice ages, new research suggests. The new ...

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. For the first time since 1972, NASA is putting science experiments on the moon in ...

Today, oxygen levels are significantly higher, weakening that feedback loop. As human activity continues to add CO₂ to the ...

Scientists now believe intense global warming could paradoxically lead to a future ice age. Learn how an ocean feedback loop ...
