Dino-Killing Asteroid

The Chicxulub asteroid which is caused the extinction of dinosaurs and drove a long-lasting era of global warming when it smashed into Earth 65 million years ago, with a rapid temperature increase of the 5-degree Celsius that endured for roughly 100,000 years, a study has found.

The monumental event is a rare case where Earth’s systems were perturbed at a rate higher than what is occurring now from human activity.

It provides valuable insights into what may happen from sudden, extreme environmental changes.

The after-effects of the Chicxulub effect remain debated, with some scientists advocating that soot within the atmosphere blocked out the Sun sufficiently to drive global cooling.

Others suggest that carbon released from the Earth’s crust into the atmosphere upon the asteroid’s effect, as well as carbon from wildfires, has a warming impact.

To better understand how the temperature changed during this time, researchers including those from the University of Missouri and the University of Colorado Boulder in the US analyzed a robust collection of well-preserved, sand-grain-sized remains of the fish teeth, scales and bone from a site in Tunisia.

These samples are retaining oxygen isotopic signatures that reveal the temperature at the time that the related animal was alive.

Researchers were able to collect samples from sediments that span the time leading up to the Chicxulub impact, until long afterward.

Based on their analysis, they propose that the global temperatures increased by about 5-degree Celsius and did not cold to previous values for roughly 100,000 years after the impact, magnitude and duration of warming strictly matching levels of carbon dioxide that some types of analyses have estimated are emitting during the same period.

So, these are the points to describe the Dino-killing asteroid caused Earth to heat up for the 1,00,000 years.
