Researchers have identified a "tipping point" about 2.7 million years ago when global climate conditions switched from being ...

Understanding history helps us make sense of the present and even make predictions for the future. It’s not just historians who study history, but scientists as well. As climate change shifts the ...

A peer-reviewed paper published in Nature Ecology and Evolution argues that the steady loss of dissolved oxygen across the world’s oceans, lakes, and reservoirs qualifies as a tenth planetary boundary ...

This shift, researchers say, marks a climatic tipping point—and it may have shaped the evolution of our species. “Things were ...

National Research Council (U.S.) Board on Earth Sciences and Resources "The hominin fossil record documents a history of critical evolutionary events that have ultimately shaped and defined what it ...

Researchers have identified a 'tipping point' about 2.7 million years ago when global climate conditions switched from being relatively warm and ...

The Cambrian Explosion in which life on Earth underwent massive diversification was likely triggered by eccentricities in Earth’s orbit around our Sun. Or so say the authors of a new paper just ...

Leipzig University researchers find the Earth's vegetation balance point shifting northeast due to carbon emissions and Asian ...

Earth would certainly be different without its rusty red neighbor. No Mars in the night sky, no target for future human exploration. Now, however, scientists say this scenario would result in much ...

Our species likes it cold. Homo sapiens evolved in — and still inhabits — one of Earth’s rare and fragile ice ages, periods distinguished not by an abundance of saber-toothed cats and woolly mammoths ...
