“Earth 2100?” –96% of Ocean Life ‘Gasping for Oxygen’ During Great Dying

 

Permian Extinction

 

The state of the planet in the late Permian—increasing greenhouse gases in the atmosphere that create warmer temperatures on Earth—is similar to today says oceanographer Justin Penn, at the University of Washington: “Under a business-as-usual emissions scenarios, by 2100 warming in the upper ocean will have approached 20 percent of warming in the late Permian, and by the year 2300 it will reach between 35 and 50 percent. This study highlights the potential for a mass extinction arising from a similar mechanism under anthropogenic climate change.”
