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 ...

They don't cause ice ages, but they do control the volume of things like glaciation and the factors that can trigger ice ages. Kane's simulations show that without Mars the frequent and intense ...

Cosmic dust can tell scientists about how ice covered Earth during the last ice age. This dust is leftover debris from asteroids and comets... What space dust reveals about Earth's ice age Around ...

A new study led by researchers at the Earth-Life Science Institute (ELSI) at Institute of Science Tokyo challenges a long-standing assumption about Earth's most extreme ice ages. Using numerical ...

Mars is half the size of Earth, with one-tenth of our planet’s mass, and at the nearest point in its orbit is over 33 million miles away. Yet new research highlights the extraordinary influence the ...

You can learn all about how the Ice Age impacted Utah at an exhibit at the Natural History Museum of Utah, for a limited time. "Mysteries of the Ice Ages" explores 18,000 years of Earth's dramatic Ice ...
