Imagine a time when the blue planet looked nothing like it does today. A time when the oceans were frozen over, the continents were locked in a thick .

Ice ages are among the most dramatic climate events in Earth’s history. They occur when long-term shifts in climate allow massive glaciers to expand across continents. These changes are influenced by ...

Earth’s climate is influenced by far more than weather patterns and greenhouse gases. Scientists have discovered that long-term orbital shifts known as Milankovitch cycles slowly change the planet’s ...

A mysterious spike of platinum buried deep in Greenland’s ice has long fueled theories of a catastrophic comet or asteroid strike 12,800 years ago—possibly triggering a sudden return to icy conditions ...

A shrinking Alpine glacier reveals a 2,000-year record of pollution, wildfire smoke, and volcanic fallout – much of it already disappearing.

Ice cores taken from glaciers reveal the air pollution of the past, using atmospheric particles incorporated in snow that fell on the glacier and became ice. Now, scientists have extracted a record of ...
