It’s not something to have pride in the extinction of dinosaurs along with all the other life forms. But a recent research by the Tohoku University in Japan has placed a number on the wretched fate of the dinosaurs. As per the latest research, there was only a 13 percent of prospect of mass extinction experience that took place 66 million years ago and if the asteroid had collided on any other surface of the earth the dinosaurs would have survived.
The Cretaceous era finished about 66 million years ago, when an asteroid approximated to be about 10 km wide wrecked into what is now the Yucatan Peninsula, Mexico. Whilst expiry would have been immediate for anything ill-fated enough to have been in the absolute line of fire, the aftermath on its own could not cause worldwide demolition. Vaporized rock and soot was discharged into the atmosphere in gigantic amounts, obstructing sunlight resulting in a nuclear winter effect deranging photosynthesis and precipitating the fall of the food chain.
According to a new study, conjecturing the gravity of the climate change would differ depending on where the asteroid hit. Domains with favorable levels of sedimentary organic material would exude soot into the stratosphere, chilling the earth more perilously than if it struck in places with lesser hydrocarbon absorption. To examine the idea, researchers utilized a global climate model to approximate the temperature peculiarity that would be an outcome of disparate degree of soot in the stratosphere.
