Scientists are warning CO2 is being emitted into the atmosphere today at a comparable rate to the amount released millions of years ago which caused the biggest extinction event in the history of the planet.
Around 90% of marine life is thought to have been wiped out in an extinctionevent known as “the great dying”, which was the bridge between the Permian and the Triassic periods 252 million years ago.
The cause of the event has been a matter of debate in the scientific community. But a team of researchers coordinated by the University of Edinburgh say they now have evidence that volcanic activity releasing huge amounts of carbon into the atmosphere caused the acidification of the oceans, wiping out the majority of life on earth.
The Permian extinction wiped out 70% of terrestrial vertebrates, and was the only known mass extinction of insects. How does that relate to ocean pH?
It is the Earth’s most severe known extinction event, with up to 96% of all marine species and 70% of terrestrial vertebrate species becoming extinct. It is the only known mass extinction of insects
An actual scientist would realize that whatever happened to kill cockroaches in the late Permian was caused by something other than a return to previous levels of CO2
Note that CO2 levels then remained high throughout the Mesozoic, as life flourished and Dinosaurs ruled the planet. Acidic scientist brains, not acidic oceans.
