New research proves that the Chicxulub asteroid strike caused the earth to warm significantly for 100,000 years



Scientists studied ancient fish to determine that the asteroid that hit Chicxulub, Mexico, 66 million years ago, raised Earth's temperatures.

A recent study by a group of scientists in the US and Tunisia has concluded that the asteroid that hit Chicxulub in Mexico 66 million years ago had a major impact on the Earth, with temperatures on our planet exceeding had heated up significantly over a period of 100,000 years.

After the impact of the Chicxulub asteroid, large amounts of carbon dioxide were able to penetrate Earth's atmosphere and raise temperatures by five degrees Celsius, according to Space . This sudden increase in temperature was discovered after analysis of teeth and bones left by old fish Phys.Org .

While scientists have long suspected that the impact of the asteroid on the Yucatan Peninsula caused the Earth's temperatures, the dust in the air caused it to drop dramatically over a period of several years.

Carbon Dioxide Finally Caused Temperatures to Boost Again and the New Study Under the guidance of Kenneth MacLeod, the lead author, there is initial evidence of the exact length of global warming that has occurred on Earth 1

00,000 years after the collapse of the Earth Asteroids Chicxulub took place on the planet.

To keep the long secret of In this phase of global warming on Earth, MacLeod and researchers had the ingenious idea of ​​looking at fossil fish to determine how long the temperature would rise.

We thought we could solve this issue by taking fossilized bits of fish teeth, dandruff and bones from the El Kef section in Tunisia. This place is known to have a nice record of the interval we are looking at – the so-called Cretaceous-Paleogene border – the mass extinction after the Chicxulub impact.

Scientists have extracted 40 fish fossils from Tunisia and examined their oxygen isotopes, taking samples from various periods before and after the impact of the asteroid. 19659011] "One of the differences is when the temperature rises, the amount of light oxygen isotope, oxygen 16, in a mineral increases relatively. We measure the ratio of oxygen 16 to oxygen 18. Every 1 part per 1000 that the ratio changes correlates with a temperature change of about 4.5 to 5 degrees [C, or 8.1 to 9 degrees F]. We found that there was a really big difference in oxygen isotopes between these three sets of samples – unambiguous. "

Kenneth MacLeod also stated that we should be very concerned about the damage we are currently doing to Earth's warming in the present time.

" When I draw a line among the teachings of this study for the modern era It would be the idea to consider that what we do in our lives will affect Earth for the next 100,000 years, which is pretty scary.

The new study, which conclusively shows that Chicxulub's asteroid stroke has raised Earth's temperatures for 100,000 years, can be found in the journal Science .
