The 'Great Dying'

A new study reveals that the End-Permian extinction event, also known as the 'Great Dying', was caused by a rapid spike in global temperatures due to volcanic activity. The researchers found that the region experienced abrupt aridification and changed climate patterns, with high-southern latitudes serving as refugia for moisture-loving...
