"An Ominous Warning on the Effects of Ocean Acidification"

"Today, researchers at the University of Bristol are publishing a study comparing what happened in the oceans 55 million years ago to what the oceans are experiencing today.

Their research supports what other researchers have long suspected: The acidification of the ocean today is bigger and faster than anything geologists can find in the fossil record over the past 65 million years. Indeed, its speed and strength — earth scientists Andy Ridgwell estimate that current ocean acidification is taking place at ten times the rate that preceded the mass extinction 55 million years ago — may spell doom for many marine species, particularly ones that live in the deep ocean.

"This is an almost unprecedented geological event," says Ridgwell."
