The idea that extreme climate change could one day cause a mass extinction and end the human dominance is not as farfetched ...

New research finds extinction rates have been declining for a century, challenging assumptions of an ongoing mass extinction.

Rapid changes in marine oxygen levels may have played a significant role in driving Earth's first mass extinction, according to a new study led by Florida State University researchers.

A fire-bellied newt (Cynops ensicauda) photographed on Amami Island (Japan). A recent study suggested that the extinction of this and other genera was part of a mass extinction event that threatens ...

New research identifies 10,443 critically endangered species worldwide, with effective protection strategies available if funding and political will follow. More than 1,500 species, or 15% of the ...

As Earth's temperature rises sharply, the threat of a global mass extinction has loomed. But U of A researchers say that fear ...

The accelerating rise in carbon dioxide (CO2) emissions caused by human activity is pushing the planet toward a potential mass extinction, as highlighted in an eye-opening Guardian article published ...

The Earth has known several mass extinctions over the course of its history. One of the most important happened at the Permian-Triassic boundary 250 million years ago. Over 95 percent of marine ...

We may not be living through Earth’s sixth mass extinction event ­­— at least not yet. That’s the conclusion of a new analysis of plant and animal extinctions published September 4 in PLOS Biology.

Almost all life on land and in the ocean was wiped out during "The Great Dying," a mass extinction event at the end of the Permian Era about 250 million years ago. New evidence suggests that the Great ...

Dinosaurs' extinction "re-engineered" Earth's surface, according to new research. The reptiles had such an "immense" impact on the planet that their sudden exit led to wide-scale changes in landscapes ...

Coral reefs didn’t merely mirror global change, but helped regulate how fast the climate bounced back from massive surges of atmospheric CO2.
