Earth 'too hot for life' after mass extinction 250 million years ago

For five million years after the worst mass extinction in Earth history, much of the planet was simply too hot for anything to survive, scientists have claimed.

  • Experts say 'broken world' that followed the Permian-Triassic mass extinction meant no life for five million years in a huge 'dead zone'
  • Temperatures in the tropics rose to lethal levels, soaring to 60C on land and 40C in the sea
