Sea surface and subsurface temperatures over large parts of the ocean during the Eocene epoch (55.5-33.7 Ma) exceeded modern values by several degrees, which must have affected a number of oceanic ...

56 million years ago, the Earth experienced one of the largest and most rapid climate warming events in its history: the Paleocene-Eocene Thermal Maximum (PETM), which has similarities to current and ...

A vast belch of gas from beneath the North Atlantic 55 million years ago may have warmed the planet and hold clues to threats from an even faster modern surge in greenhouse gases, scientists reported ...

A new study of the High Arctic climate roughly 50 million years ago led by the University of Colorado at Boulder helps to explain how ancient alligators and giant tortoises were able to thrive on ...

Thanks to unbridled greenhouse gas emissions, our planet is stitching together a climate version of Dr. Frankenstein’s monster. We still have ice from the warmer parts of the Pleistocene even as our ...

As the Atlantic grew wider, the ancestral population of all of today's oaks may have been straddling the continents of the Northern Hemisphere. If so, the ancestor of the oaks we know today was a ...

Ancient climate cooling reshaped carnivoran bodies, with fossils revealing how habitats drove species diversity worldwide.

New research led by the University of Washington suggests that two different climate transitions millions of years ago fueled the diversification of carnivoran body plans.
