Explanation – The Carnian Pluvial Episode (CPE) occurred approximately 234 to 232 million years ago during the Late Triassic period. It was marked by significant climatic changes, including increased global temperatures, humidity, and rainfall. This period of intense global rainfall was triggered by volcanic eruptions, particularly from the Wrangellia Large Igneous Province. These eruptions released large amounts of greenhouse gases like carbon dioxide into the atmosphere, leading to global warming and an intensified hydrologic cycle, which resulted in increased rainfall and runoff.
