Scientists conclude that while volcanic eruptions caused a temporary cold period, the effects had worn off thousands of years before the meteorite impact, making the impact the definitive cause of the dinosaur extinction.
While volcanism caused a temporary cold period, the effects had already worn off thousands of years before the meteorite, the ultimate cause of the dinosaur extinction event, impacted. Massive volcanic eruptions on the Indian peninsula have long been proposed as an alternative cause for the demise of the dinosaurs. This phase of active volcanism took place in a period just before the Earth was struck by a meteorite, 66 million years ago.
The effect of these volcanic eruptions on the Earth's climate has been topic of fierce scientific debates for decades. Now, climate scientists from Utrecht University and the University of Manchester show that, while the volcanism caused a temporary cold period, the effects had already worn off thousands of years before the meteorite impacted. The scientists therefore conclude that the meteorite impact was the ultimate cause of the dinosaur extinction event. What killed off the dinosaurs -- was it the Chicxulub meteorite or did the effects of massive volcanism also play a role? Many modern children's books on the history of dinosaurs include speculation on these two competing ideas. The meteorite impact in the Gulf of Mexico roughly 66 million years ago is well researched and widely known as the defining end of the dinosaur age. But earth scientists have fiercely debated for decades whether a massive outpouring of lava on the Indian continent, which occurred both prior to and after the meteorite impact, also contributed to the demise of dinosaur populations roaming the Earth. These volcanic eruptions released vast amounts of CO, dust, and sulphur, thereby significantly altering the climate on earth -- but in different ways and on different timescales to a meteorite impac
