Earth endured over one million years of rain in the "Carnian Pluvial Event"


A period known as the Carnian Pluvial Event, which occurred about 232 million years ago, marked a dramatic turn in Earth's climate history

The primary driver behind this extraordinary shift in climate appears to be a massive volcanic eruption within the Wrangellia Large Igneous Province, stretching from south-central Alaska through the coast of British Columbia. Jacopo Dal Corso, a researcher involved in studying the event, highlighted the eruption’s colossal impact on the atmosphere, with the discharge of greenhouse gases such as carbon dioxide triggering spikes in global warming. Ultimately, the drastic climate changes of the Carnian Pluvial Event paved the way for new forms of life to emerge and diversify, setting the stage for the dominance of dinosaurs and other modern terrestrial fauna.
