There are plenty of mysteries left to discover out there, including entirely new species of animals that can weigh over 200 ...

What the Pliocene epoch can teach us about future warming on Earth. About 3 million years ago, carbon dioxide levels were similar to today’s. What other changes might we expect?

For decades after Lucy's discovery, paleoanthropologists assumed A. afarensis was the only hominin that lived in this region ...

Before we put ourselves on a clear path to overshooting the maximum global heating target we set for ourselves, a different epoch, the Pliocene (which took over from the Miocene and ended just 2.4 ...

The Pliocene epoch was a paradise for primates. But that ended 2.6 million years as ice sheets started to expand.

As it turns out, 36 percent of marine megafauna died out at the end of the Pliocene epoch. That’s over a third of the mammals, sharks, turtles, and seabirds that died out as the climate changed.

The identified species lived during the Pliocene Epoch, which lasted between 2.6 and 5.3 million years ago. During that epoch was the period of time known as the Stone Age, and just after the ...

Rising CO2 levels are pushing earth beyond any climatic conditions ever experienced by humans, scientists warn. Global mean temperatures are rising much faster than any time since the Pliocene ...

In fact, atmospheric levels of carbon dioxide are similar to where they were during the mid-Pliocene epoch, about 4.3 million years ago, NOAA said.

Atmospheric levels of carbon dioxide are now similar to where they were during the mid-Pliocene epoch, about 4.3 million years ago, NOAA said.

They have concluded that the most revealing slice of time is the Pliocene Epoch, a warm, wet period between 3.15 million and 2.85 million years ago, when the world probably looked and felt much as ...

In the Pliocene epoch, the growth of ice at the poles led to frequent sea level changes and loss of important offshore habitats. An accompanying extinction event led to a decline in large prey, ...
