Large changes in global sea level, fueled by fluctuations in ice sheet growth and decay, occurred throughout the last ice age ...

When the planet was heating up at the end of the last Ice Age, ice-melt flooded out by glaciers made oceans rise. Scientists ...

Throughout most of Earth's geological history, its paleoclimate has remained hospitable to life—largely thanks to continental ...

What can craters on Mars teach scientists about the Red Planet’s climate history? This is what a recent study published in ...

New research reveals how the Earth might overcorrect for global warming. For a long time, scientists believed that the gradual breakdown of silicate rocks played the leading role in regulating Earth’s ...

Buried Louisiana marshes show North America, not Antarctica, fueled the world’s dramatic sea level surge 9,000 years ago.

Nearly 10,000 years ago, Earth came out of its most recent ice age. Vast, icy swaths of land around the poles thawed, melting the glaciers that had covered them for nearly 100,000 years. Why, after ...

For decades, scientists have been curious about how much water Mars once had and what led to its gradual transformation into ...

MINNEAPOLIS / ST. PAUL–The widely accepted theory that changes in Earth’s orbit drive cycles of glaciation can’t account for an early thawing of glaciers from the next-to-last ice age, according to ...

CORVALLIS, Ore. (KVAL) — During the last ice age, massive icebergs periodically broke off from an ice sheet covering a large swath of North America and discharged rapidly melting ice into the North ...

New study shows Mars went through shrinking ice ages, revealing how it lost water and where future missions might find what's ...
