Humans Emitting Carbon Dioxide 200 Times Faster Than Supervolcanic Eruptions That Caused Earth’s Most Severe Mass Extinctions

“Earth’s biological cycle has been punctuated by catastrophic mass extinctions, some of which wiped out 90% of all species,” Dr. Jiang said.

“The main culprit of these rapid environmental crises were massive volcanic eruptions. What had been puzzling scientists is that some of these gigantic eruptions resulted in severe extinctions, while others only resulted in minor environmental disturbances. We set out to discover why.
