Cooking an early group extinction of our planet and erasing most of life

252 million years ago, the volcanic revolutions in Siberia in the modern era led to 100 trillion metric tons of carbon dioxide (CO2) to the air over a million years. This natural catastrophe, called “Great Death”, killed most animals on this planet. New research shows that it has also changed the ecosystems of the Earth.

An international team of researchers used climate models and vegetable fossils to connect great death with an increase in Fahrenheit 18 degrees (10 degrees Celsius) at medium global temperatures. Their work, detailed in a Ticket It was published on Tuesday in Frontiers in Earth Science, providing an insight into how to change carbon dioxide emissions in humanity significantly.

The researchers focused on five time periods that include parts of the cellular and prey: Wokiaking and Changinjian, Triassic’s Induan, Olenekian, and Anisian. The great death represents the transition from the Perious era to the terminal period, so it is often referred to as blind collective extinction, or the software-estranged boundaries. If “Tresic” is familiar, then this is the period that witnessed the rise of dinosaurs, whose ancestors survived the great death.

“Life on Earth had to adapt to the repeated changes in the climate and the carbon cycle for several million years after the programmatic limits-the main author Mora Brunei, a researcher at the Applied Physics Institute group at Geneva University, in the front, at the front, statement.

BRUNETTI and its colleagues estimated the changes in six different vital matches (distinctive environmental habitats) through the above periods of time through the analysis of vegetable fossils and simulating the computer model in light of different scenarios of temperatures and CO2 levels, then indicate their results. The vital areas included African vital areas (hot and wet), tropical or monsoons (volatile conditions), and desert (dry) vital navigations.

On a large scale, the researchers revealed that the blind period was cold, Indois was not clear (more research was needed), and UNICEAN and Anzian were hotter. “This transition from the cold climatic state to the hottest condition is characterized by an increase of about 10 ° C (18 ° F) in the average global surface air temperature,” Brunei explained. This is consistent with the huge quantities of carbon dioxide, which the volcanic explosions were launched in the air – the upper levels of carbon dioxide, the warmer the planet.

It is not surprising, the researchers found that the vital areas changed dramatically during this transition. “Eype Equatorial and SumingWet clubs appeared in the tropics, to replace the landscape mostly,” BRUNetti continued. “Meanwhile, the warm moderate Biome turned to the polar areas, which led to a complete disappearance of the ecosystems of tundra.” Simply put, the deserts were replaced near the equator. The tropical and cold Tindra views were turned near the pole with moderate forests.

“The shift in the vegetation cover can be linked to the irreversible transformation mechanisms or transformations, between the stable climate periods, which creates a possible framework” understanding the behavior of the climate system in response to the excess of the current carbon dioxide. ” “If this increase continues at the same rate, we will reach the level of emissions that have caused the extinction of the throwing mass in about 2700 years-on a timetable much faster than the code border emissions.”

While researchers warn that more research is needed to confirm their results, the study can be explained as a blatant warning: in the very long term, human emissions of carbon dioxide can significantly change the planet from great death.
