Comment on this resource
This article provides a model for climatic change and relates climatic cycles with major extinction events in the history of the Earth. It discusses the mechanisms behind modern climate zones (circulation, storm systems, seasons), astronomical models, climatic models (obliquity conditions, rising sea levels, current conditions), and mass extinctions and model timing (causes of extinction events, predicted vs. documented extinctions, and extinction-driven evolution). A geologic time scale provides a reference for climatic conditions at different periods in Earth history. References are provided for additional information.
