The rapid climate change we are experiencing today is mainly driven by the greenhouse gases we humans keep releasing into the air. But new evidence from ancient Antarctic ice cores suggests this ...

Deep beneath glaciers and polar ice caps lies Earth’s climate history—preserved in frozen layers over hundreds of thousands of years. Ice cores act as time capsules, helping scientists study past ...

Drilling through 500 feet of floating ice into the Antarctic Ocean floor, climate scientists have retrieved a rare 23-million-year record of sediments that helps demonstrate why the planet’s southern ...

Researchers have identified a "tipping point" about 2.7 million years ago when global climate conditions switched from being relatively warm and stable to cold and chaotic, as continental ice sheets ...

An ice-core record of hydrogen reveals that atmospheric levels vary in response to climate change and have increased drastically owing to human activity since the pre-industrial era. The apparent ...

The last ice age began roughly 120,000 years ago and ended about 11,500 years ago, but plenty of signs of this last period of ice domination still exist all over Earth. The Midwestern United States ...
