Global Warming also caused by Dinosaur-Killing Asteroids

The asteroid which has impacted the age of dinosaurs which are ended their life after hitting the earth also released so much carbon dioxide into the atmosphere, and it increases the planet by warming up it up by about 5 degrees Celsius and this spell persisted for roughly 100,000 years.

According to a new study, which was published in the journal Science which offers the cautionary tale about the Earth’s climate and it will react with the carbon dioxide which is being pumped into the atmosphere by burning the fossil fuels.

Scientists have already wondered about the long-term environmental effects of the Chicxulub impact which was occurred about 65 million years ago. This happened when a space rock which is more than 5 miles wide had slammed into the Yucatan Peninsula, and the crash must have produced a blast of intense heat that vaporised rock and set off the massive wildfires.  

After the effect, a vast cloud of ash is seen, and this cloud of ash must have blocked the sun for months, years and usher the global winter which has killed off plants and animals in the mass extinction. When the skies get cleared, researchers believed that the planet must have got warmed up till that time due to fires and zapped minerals and as a result of a lot of carbon dioxide in the atmosphere.

According to the Page Quinton, who is the geologist at the State University of New York at Potsdam said, “To date, there have been no good empirical estimates on what temperature is doing following the impact, regarding hundreds of thousands of years.” She had worked with Ken MacLeod, who is the paleontologist at the University of Missouri, Columbia and look at one possible recorder of temperatures which is oxygen isotope signatures from the fossils of fish that were alive way back then. The bits of the fish remain so small that they look like grains of sand or crud.

As per MacLeod, he said by adding, “But under the microscope, they are unequivocally fish fossils. They’re these millimetre or half-millimetre long little teeth, and under the microscope they are gorgeous. They also found the tiny fish scales or bits of bone.” The researchers have searched them in pounds of rock from El Kef, Tunisia which is the place in which there was well-preserved rock layer which spans from the time periods both before and after the asteroid impact.
