The planet has experienced five mass extinction events. The worst, the Permian Mass Extinction event 252 million years ago, annihilated more than 95 percent of all life on Earth. It coincided with a significant increase in atmospheric carbon dioxide (CO2).

The Permian Mass Extinction is the perfect example of what happens when you inject too much CO2 into the atmosphere. The way in which the oceans absorbed this CO2, and subsequently acidified, was the primary kill mechanism for that event.

Disturbingly, a scientific paper published last week in the journal Science Advances, titled “Thresholds of Catastrophe in the Earth…
