Life on Earth snuffed out by global warming

SUFFOCATING global warming is to blame for the worst mass-extinction on Earth, according to international researchers tracking the cause of the “Great Dying” 250 million years ago.

Until now, circumstantial evidence suggested that an asteroid wiped out more than 90 per cent of all marine life and almost 75 per cent of all land plants and animals, like that which took out the dinosaurs 65 million years ago.
