Since scientists first determined that atmospheric carbon dioxide (CO2) was significantly lower during ice age periods than warm phases, they have sought to discover why, theorizing that it may be a function of ocean circulation, ...

In a kind of geological mystery, scientists have known for decades that a massive ice sheet stretched to cover most of Canada and much of the northeastern U.S. 25,000 years ago. What's been trickier to pin down is how—and ...

Graphs of global sea levels around the time of the poorly understood Last Glacial Maximum (27,000 to 20,000 years ago) previously showed stable ice sheets for about 10,000 years before the ice slowly started to melt. New ...

The critical role that breast feeding plays in infant survival may have led, during the last ice age, to a common genetic mutation in East Asians and Native Americans that also, surprisingly, affects the shape of their teeth.

At 3.5 meters long and with a shoulder height of 1.7 meters, the cave bear was one of the giants of the Ice Age. Yet few appear to have survived until the last glacial maximum 24,000 to 19,000 years ago. Researchers from ...
