Relationship between extinction magnitude and climate change during major marine and terrestrial animal crises

22 July 2022

The author found a good correlation between the mass extinction magnitudes of animals and surface temperature anomalies. The relation is good regardless of the difference between warming and cooling. Marine animals are more likely than tetrapods to become extinct under a habitat temperature anomaly. The extinction magnitudes are marked by abrupt global surface temperature anomalies and coincidental environmental changes associated with abrupt high-energy input by volcanism and impact.
