Beginning around 2.5 million years ago, Earth entered an era marked by successive ice ages and interglacial periods, emerging from the last glaciation around 11,700 years ago. A new analysis suggests ...

The earth (and humanity) would be very different without our smaller red neighbor. In A Nutshell Computer simulations show ...

While the Milankovitch Cycles operate on timescales far longer than human lifespans, their effects are always at play.

Around 20,000 years ago, Earth was very, very cold. Global temperatures were 10 degrees Fahrenheit colder than they are today and most of North America was covered in ice. That ice was almost half a ...

While the Earth has gone through some dramatic climate changes in its 4.6-billion-year history, natural processes like silicate weathering can help return things to a comfortable equilibrium. A new ...

Scientists have determined exactly how Earth's orbit and tilt affect glaciation and deglaciation, based on the length of these parameters' cycles and clues hidden at the bottom of the ocean. When you ...

Earth has experienced several climate cycles throughout its long history, including several ice ages that caused the planet to freeze over. The last ice age occurred approximately 11,700 years ago, ...

As the last Ice Age came to an end nearly 10,000 years ago, something unexpected happened deep beneath Earth’s surface. Large glaciers began to melt. The sea levels rose quickly—about 1 centimeter per ...

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 climate's trajectory. Credit: Matt ...
