The Great Warming Extinction was Even More Deadly Than Believed
Life about 250 million years ago was hard to come by. In fact, it was nearly non-existent. Scientists, studying why this period, known as the end-Permian event, lasted so long and have found a key ingredient: heat.
Paul Wignall, a paleontologist at England’s Leeds University, and study coauthor, said during the 200,000-year-long Permian extinction the Earth began cooking, with life struggling to thrive, especially at the equator.
