Scientists say small changes in the way the Earth orbits the sun hold the key in major global changes in climate, like ice ...

Earth’s climate follows a natural cycle of ice ages and warm periods. A new study shows that small orbital changes drive ...

Earth’s climate has never been static. It shifts between warm interglacial periods and deep freezes, driven by complex ...

Over 700 million years ago, Earth experienced a dramatic climate event known as the Sturtian glaciation, one of the most ...

Find out what scientists say about the Next Ice Age and the natural rhythms shaping our planet's climate over millennia.

The research, published Thursday, February 27, in the journal Science, found a strong connection between Earth’s axial tilt ...

It has been assumed that changes in the Earth's orbit around the sun are responsible for the ice age cycles. It is now clear ...

The work elucidates how it came to pass. Obliquity causes variation in seasonality over a 41,000-year period, which affects how much total energy the higher latitudes get in summer. Precession changes ...

As massive glaciers scratched and scarred Earth’s rocky surface, they freed less-common minerals, which were later flushed into the seas as the ice melted into giant glacial rivers. These minerals in ...

Despite decades of research, precisely how the various parts of the solar insolation cycles affect glacial cycles is not ...

Scientists have long known that Earth’s climate goes through cycles of ice ages and warmer periods. Around 2.5 million years ago, the planet entered a phase marked by repeated ice ages, with the most ...

Ancient glaciers triggered floods that altered ocean chemistry, supporting evolving life. Scientists uncover how past events ...
