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 ...

Around 14,500 years ago, toward the end of the last ice age, melting continental ice sheets drove a sudden and cataclysmic sea level rise of up to 65 feet in just 500 years or less. Despite the scale ...

For decades, scientists puzzled over two key climate mysteries. What sparked the formation of Earth’s vast ice sheets during the last ice age—and how did they spread so fast? New research may finally ...

Mars’s Coloe Fossae reveals a landscape shaped by ancient ice ages, with deep valleys, cratered terrain, and frozen debris flows preserved from a time when the planet’s climate dramatically shifted.
