Wildfires May Have Sparked Ecosystem Collapse During Earth's Worst Mass Extinction
Researchers at University College Cork (UCC) and the Swedish Museum of Natural History examined the end-Permian mass extinction (252 million years ago) that eliminated almost every species on Earth, with […]

Three Critical Factors In The End-Permian Mass Extinction
The end of the Permian was characterized by the greatest mass extinction event in Earth’s history. 252 million years ago, a series of volcanic eruptions in Siberia led to a […]

Volcanic Eruptions Directly Triggered Ocean Acidification During The Early Cretaceous
Around 120 million years ago, the earth experienced an extreme environmental disruption that choked oxygen from its oceans. Known as oceanic anoxic event (OAE) 1a, the oxygen-deprived water led to […]

Estimating Survival Probability Using The Terrestrial Extinction History For The Search For Extraterrestrial Life
Several exoplanets have been discovered to date, and the next step is the search for extraterrestrial life. However, it is difficult to estimate the number of life-bearing exoplanets because our […]
