FRANCE: They call it the Great Dying because it was the biggest mass extinction in history, and now scientists have discovered the first hard evidence that ocean acidification was the coup de grace that killed off more than 90 per cent of marine life 252 million years ago.
In a disturbing parallel to what is happening in the sea today, researchers have found chemical signatures in ancient rock formations showing that the oceans at that time suddenly became more acidic, making it impossible for the vast majority of sea creatures to survive.
Scientists believe that the dramatic acidification of the oceans at the end of the Permian period was caused by the continual eruption of super-volcanoes which generated the release of massive volumes of carbon dioxide at a rate comparable to the levels of CO2 that humans are pumping into the atmosphere at the present time.
