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 ...

Earth naturally cycles between ice ages and warm periods based on three astronomical cycles: precession (Earth’s wobble), ...

Earth’s climate balance isn’t just governed by the slow weathering of silicate rocks, which capture carbon and stabilize temperature over eons. New research reveals that biological and oceanic ...

Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, send it to [email protected]. How many ice ages has the Earth had, and could ...

At the edge of East Antarctica, where the wind howls through a white emptiness and the air bites harder than steel, ...

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 ...

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 ...

Scientists found six-million-year-old ice in Antarctica, unlocking the planet’s oldest samples and evidence of dramatic long-term cooling.

Sea levels rose and fell many times during the ice age, showing ice sheets were larger and more active much earlier than once believed.

The ice sample, retrieved in Antarctica, is the oldest on record—but this discovery may just be tip of the iceberg.

Earth's mantle is so gooey, it takes eons for material that has been displaced by the weight of ice sheets to flow back. And ...
