Warming ‘Wiped Out’ Most Life 250 Million Years Ago

A slow process of climate warming rather than a comet or asteroid impact led to Earth’s biggest mass extinction, according to research.
Scientists have found no evidence of a major impact around the time of the event, known as the “Great Dying,” 250 million years ago.
They believe the extinction was the result of global warming due to volcanic eruptions and a drop in oxygen levels.
The findings provide an ominous glimpse of what can happen when the climate heats up over a long period.
