An extinction in the blink of an eye. MIT researchers

find that the end-Permian extinction happened in

60,000 years — much faster than earlier estimates.

Huge and widespread volcanic eruptions triggered the

end-Triassic extinction. Some 200 million years ago,

an increase in atmospheric CO2 caused acidification

of the oceans and global warming that killed off 76

percent of marine and terrestrial species on Earth.
