Subglacial water in Antarctica reshapes sea level rise predictions and reveals ancient drainage flow patterns.

For decades, scientists believed Antarctica’s first large ice sheet formed around 34 million years ago during the Eocene-Oligocene transition. This cooling event transformed the continent into ...

The team observed that subsurface rivers have moved around a lot, which has affected where and how the ice might shatter or ...

Analyses of pollen and spores and the remains of tiny creatures have given a climatic picture of the early Eocene period, about 53 million years ago. The study in Nature suggests Antarctic winter ...

Indeed it was so warm that trees grew in both the Arctic and Antarctic, and alligators lived in Ellesmere Island at 78 degrees North. But this warm period, called the Eocene, was followed by a ...

The warmer atmosphere holds more water vapor, which falls as snow on East Antarctica. But even this behemoth is unlikely to survive a return to an Eocene Climate. West Antarctica: Like the ...

The red star indicates the position of South Orkney during the late Eocene (37 million years ago). The blue regions indicate where Antarctica may have had land ice at the time. The grey and light ...
