Earth was ‘too hot for life’ 250m years ago
Earth was too hot for anything to survive for a period of five-million-years after the worst mass extinction in the history of the planet, scientists claim.
Experts have long been puzzled by the ‘broken world’ scenario that followed the Permian-Triassic mass extinction 250-million-years ago.
Up to 96 per cent of all marine species and 70 per cent of land-dwelling vertebrates were wiped out by the event, thought to have been caused by a combination of climate change and volcanic activity, the Daily Mail reported.
Typically it takes tens of thousands of years for new species to appear after a mass extinction. However, in the case of the Permian-Triassic event, this “dead zone” lasted an extraordinary five-million-years.
Temperatures in the tropics rose to lethal levels, soaring to 60ºC on land and 40ºC in the sea, and prevented life re-emerging.

Britney to call off wedding?
London: Britney Spears is reportedly set to cancel her wedding to Jason Trawick. The 30-year-old singer is said to be wondering if her relationship is nothing but a business deal cooked up by her father, reported Showbizspy.
“I think Britney’s father hired Jason to be her watchdog from the very beginning. If that is true, and she has finally figured that out, she will call off their wedding,” a source said. After Britney’s mental breakdown in early 2008, her father became her legal conservator. But he got tired of keeping tabs on her and reportedly hired Trawick as her agent at William Morris. — PTI
