Earth Orbit Changes Key to Antarctic Warming That Ended Last Ice...

For more than a century scientists have known that Earth's ice ages are caused by the wobbling of the planet's orbit, which changes its...

Ancient Trapped Water Explains Earth’s First Ice Age

Tiny bubbles of water found in quartz grains in Australia may hold the key to understanding what caused Earth's first ice age, say scientitss. The...

Arctic Current Flowed Under Deep Freeze of Last Ice Age, Study...
