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

According to a new study, changes in Earth’s tilt have driven the rise and fall of massive ice sheets for the past 800,000 ...

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

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

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 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 ...

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 ...

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 ...

The Earth's next ice age is expected to begin in about 11,000 years -- unless human-caused global warming disrupts natural ...

Beginning around 2.5 million years ago, Earth entered an era marked by successive ice ages and interglacial periods, emerging ...
