Rampant wildfires once led to global mass extinction, scientists say. Can it happen again?

A long time ago, it was a carbon stone, secretly buried in the ground as a secret. Then unprecedented environmental catastrophes began. The rocks burned, and the atoms in them dispersed into carbon dioxide and other greenhouse gases.

The temperature was rising and wildfires – always part of the natural ecosystem – became more frequent and more intense. The forests were destroyed by the fire. At one point, carbon dioxide was released into the atmosphere, which became hotter and drier, and the fire was started faster.

Where there are no trees, nutrients flow into the lakes and streams. Those nutrients fed the poisonous algae, and other species starved.

By the end of the day, up to 95% of the world’s oceans live, and more than 70% of them are dead.

New research shows that the fires of 252 million years ago were not only a sign of global warming but also of extinction. Increasing fires have damaged plants’ ability to adapt, and they themselves have endangered the lives of those who have not been exposed to the flames — scientists fear they are still doing so.

These events took place in what is known as the Last Perm, or the Great Death. For tens of thousands of years, between the birth of the Panga-born supercontinental Panga and the emergence of the first dinosaurs in Triassic, a series of interconnected climate disasters have claimed most of the planet’s life.

Although millions of years have identified the threat of the Great Death from the wildfires of modern forests, the new study shows the similarities between those ancient global warming and our own.

Chris Mies, a fossil researcher and lead author at the University College of Cork in Ireland, said in a study published last week that “there is a similarity between the present and the past.” Pallaius.

Today’s hurricane echoes the effects of high temperatures, declining rainfall, and more fires in Permania, which has led to delays in climate change, Meiss said.

Although those catastrophic events have been going on for thousands of years, the effects are alarming.

“We’ve been warming the world for hundreds of years, and as the temperature rises and the environment changes rapidly, there’s a good chance the ecosystem will deteriorate,” Mayes said. “The pace of change is really important. And it’s a very worrying place today.”

Long before the species began to die en masse, wildfires and other natural phenomena were a common occurrence during the Permian period. According to a study by Eastern Australia and Antarctica, Maes and his Swedish Museum of Natural History were set in the midst of fossil fuels, the signature of a prehistoric fire. The fossil record shows that plants, as they do today, have evolved to protect themselves from fire and to regenerate quickly after an occasional fire.

Things have changed since the eruption of the volcanic eruption in the Siberian region of Russia. Lava and greenhouse gases have been emitted from the volcano for nearly 2 million years, less like Vesuvius and the Hawaii Volcano National Park.

During this time, large amounts of greenhouse gases are dramatically warming the earth. Average global temperatures range from 6 to 12 degrees Celsius (11 to 22 degrees Fahrenheit) around the equator, and 10 to 14 degrees Fahrenheit (18 to 25 degrees Fahrenheit) around the poles. (Climate scientists warn that today, global warming by 2 degrees Celsius could kill 99% of the planet’s coral reefs and cause the collapse of polar ice caps.)

In this hot, dry climate, the frequency of fires is higher than plants can adapt. They could no longer ensure the sustainability of the forest, and a significant source of carbon storage was lost.

“Extreme climate change and extreme fire activity during the extinction period seem to have pushed these fire-resistant plants to extremes, and the whole ecosystem has not recovered for millions of years,” he wrote.

Understanding the catastrophic destruction on this planet provides valuable insights into future environmental disasters. The Meiss team eventually lost to the tropical forests.

Reagan Forest, which did not participate in the new, “Even ecology in protected areas – wetlands, riparian areas, as this article says – even those ecosystems are prone to warming and dry areas,” said the non-participating Poliobotan Reagan Forest. Study. “Then a flash can really change the ecosystem.”

The forest is examining the significant role played by wildfires in the extinction of a quarter of 15,000 years ago. That climate change (and introducing people as hunters) ended the excavations of La Bre Tart Pitts, later on by Dan’s helper, the Saber-tooth cat, American camel, mastodone, and other species.

Of course, after the great death, life was restored. A study of fossils in southern China shows that sea urchins are among the first to recover after the end of Permium. Paper published last week Advances in science Evidence suggests that subterranean animals were better equipped to stem the tide.

David Botger, a paleontologist at the University of Southern California, said: “Of course, we can see how it will recover. But this recovery has lasted like a million years or more.”

Predictable man-made temperatures are not as severe as the Earth’s pre-season temperature fluctuations. But these anthropological-oil changes happen faster than natural ones.

“Nature has already begun experimenting,” says Botger. “It’s not a beautiful sight.”

During a catastrophic mass destruction, wildfires may have caused an ecological collapse.
