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 ...

The last ice age did not shut down Atlantic ocean currents, and that discovery may help explain future climate risks.

Scientists have uncovered a missing feedback in Earth’s carbon cycle that could cause global warming to overshoot into an ice age. As the planet warms, nutrient-rich runoff fuels plankton blooms that ...

A group of scientists think they can now predict when the next ice age could grip Earth, but don't worry, it's not for a very long time. An ice age should begin in about 10,000 years, but its onset is ...

A new study published last week is giving us a better idea. The research builds on previous hypotheses theorizing that Ice Ages occur on a predictable timeline that relates to the geometry of Earth’s ...

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, ...
