For decades, we believed that outside ice ages Europe was mostly covered by dense forest before the arrival of modern humans. Now, a new study shows that there was far more open and semi-open ...

Visualize the following: The Earth's climate swings between cold glacial and warm interglacial periods; the last glacial interval was about 20,000 years ago; sea level was about 126 meters (413 feet) ...

Carbon dioxide levels in the atmosphere vary naturally between ice ages and interglacial periods. A new study by researchers at the University of Gothenburg shows that an unexpectedly large proportion ...

Speleothems turned out to be a great stroke of luck: dripstones from two caves in the Swiss Alps provide for the first time a continuous reconstruction of temperatures during the Last Interglacial ...

A million years ago, the interglacial periods were relatively cool. Then, 430,000 years ago, they switched to milder conditions that resemble our own. A new paper looks at what drove this change.

FARGO — The last 2.6 million years on Earth is known as the Ice Age. Continental Drift caused changes to ocean currents, allowing Earth's climate to cool enough for significant amounts of water to ...
