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 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 ...

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

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 ...

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 ...

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 ...

On Feb. 28, seven planets will all grace the early evening sky.
