A Dartmouth-led study on ice cores from Alaska and Greenland found that air pollution from the burning of fossil fuels reaches the remote Arctic in amounts large enough to alter its fundamental ...

Scientists have drilled 1.7 miles deep into Antarctica, pulling up an ice core sample that dates back at least 1.2 million years. They expect the sample to offer new insights into the evolution of ...

Frozen deep beneath Antarctica and Greenland lies something remarkable. Tiny bubbles of ancient air, locked away in ice for hundreds of thousands of years, hold secrets about our planet's past.

A group of scientists is in a race against time in the Arctic. Valuable climate data is at risk of disappearing as our overheating planet melts glacier ice. Our warming world is melting glaciers and ...

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 ...
