Global warming risks most cataclysmic extinction of marine life in 250m years

New research warns pressures of rising heat and loss of oxygen reminiscent of ‘great dying’ that occurred about 250m years ago

Global heating is causing such a drastic change to the world’s oceans that it risks a mass extinction event of marine species that rivals anything that’s happened in the Earth’s history over tens of millions of years, new research has warned.

Accelerating climate change is causing a “profound” impact upon ocean ecosystems that is “driving extinction risk higher and marine biological richness lower than has been seen in Earth’s history for the past tens of millions of years”, according to the study.
