The most dramatic example of climate induced extinction that many of us learned about as children would be the Cretaceous–Paleogene (K–Pg) extinction event 66 million years ago. This was most likely exogenous (caused by an enormous asteroid) but it still resulted in the "sudden mass extinction of three-quarters of the plant and animal species on Earth." Most notably this included the extinction of all non-avian dinosaurs. https://en.wikipedia.org/wiki/Cretaceous%E2%80%93Paleogene_extinction_event https://en.wikipedia.org/wiki/Cretaceous%E2%80%93Paleogene_e...
