The world’s oceans are at the tipping point of being starved of oxygen leading to mass sea life extinction which could last a million years, University of Exeter scientists fear.
The modern ocean is “on the edge of anoxia”, when the seas are depleted of oxygen. The researchers studied the Toarcian Oceanic Anoxic Event, which took place 183 million years ago. This was characterised by a major disturbance to the global carbon cycle, depleted oxygen in the Earth’s oceans and mass extinction of marine life.
