Scientific Study Finds Asteroid Dust Cloud Caused Lethal Thermal Conditions for Dinosaurs
Just the facts
A study published by researchers suggests that the asteroid impact 66 million years ago created a global dust cloud that elevated atmospheric temperatures to lethal levels. According to the scientific model, the fine silicate dust remained suspended in the atmosphere, trapping heat and creating a "global oven" effect. This intense thermal radiation would have roasted many terrestrial organisms, including dinosaurs, within hours of the impact. The findings offer new insights into the precise mechanisms that led to the Cretaceous-Paleogene mass extinction event.
Why this is news
A new scientific study published in an academic journal proposes a revised model for the extinction of non-avian dinosaurs.
