Prehistoric climate change due to cosmic crash in Canada: Team reveals cause of global climate shift 12,900 years ago
For the first time, a dramatic global climate shift has been linked to the impact in Quebec of an asteroid or comet, Dartmouth researchers and their colleagues report in a new study. The cataclysmic event ...
New finding shows climate change can happen in a geological instant
(Phys.org) —"Rapid" and "instantaneous" are words geologists don't use very often. But Rutgers geologists use these exact terms to describe a climate shift that occurred 55 million years ago.
