SUMMIT COUNTY — One of the last episodes of extreme global warming resulted in a near-total breakdown of Earth’s biological systems — a 5-million-year ‘dead zone’ at the start of the Triassic period during which almost no new species appeared.

A study jointly led by the University of Leeds and China University of Geosciences (Wuhan), in collaboration with the University of Erlangen-Nurnburg (Germany), shows the cause of this lengthy devastation was a temperature rise to lethal levels in the tropics: around 50-60 degrees Celsius on land, and 40 degrees at the sea-surface.
