Scientists have determined exactly how Earth's orbit and tilt affect glaciation and deglaciation, based on the length of ...

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

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 ...

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

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 history is a roller-coaster of climate fluctuations, of relative warmth giving way to frozen periods of glaciation ...

Glacial cycles aren’t random; they follow a predictable rhythm dictated by Earth’s orbit. A study analyzing climate records ...

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