Today's global warming reflects the situation that is in place; Following to a biggest event on Earth, a study says

"Less than one percent of Permian Harbor was a dead division – very similar to today's day," said Deutsch.

There is a series of volcanic events in Siberia that many scientists believe they are; extinct "volcanoes are like a pin," said Seth Burgess, a geologist and volcano expert with the United States Geological Survey.

"We talk about enough lava that is gutting on the surface and disrupting its lock to install the United States area United, if you were watching the US from above, it's been worth a deep kilometer, "he said.

Burgess, who has researched the Siberian Traps volcanic events but did not work on the new Science paper, scientists said that magma is rising from the ground; dispose of some greenhouse gases that cause banning.

In addition, magma rods still exist within the ground that heat large deposits of coal, peat and carbonate minerals, among others, including more carbon and meat to the atmosphere.

"Without the way you drive Permian mill out, by inserting a lot of magma into your sediments that go to it. ; carbon-rich behavior, "he said.

UW and Stanford research "provides the next step in determining why death at the end of Permian died," said Burgess. "It's the twins we're thinking about what happened in the weather with a fossil record, and it's doing it well."

He took a supercomputer for more than six months to make all the changes to think the volcanic brushes in the Permian era. Computing modules will go to amazing details – a & # 39; Imagine things such as clouds, sea streams and marine plant life – in describing the temperature and conditions similar to Earth.

The researchers identified that surface temperature rises about 10 C in the tropics due to prior scientific analysis of fossil teeth of eel-like creatures called conodonts.

To run their model, researchers installed volcanic greenhouse pumps into their imagination to match the temperatures at the end of the Permian period.

As temperatures climb into the 10-step signal, oceans have been reduced by oxygen, as scientists have been able to reduce their temperatures. Evaluation of values ​​in today's seas too.

To measure how rising temperatures and fewer oxygen effects affecting Permian species, creators used 61 new creatures – crustaceans, fish, shellfish, corals and sharks. Researchers believe that there would be similar temperatures and an oxygen awareness of Permian's species as the animals would be suited to live in a similar climate.

The creatures discovered the duplication of duplication of creatures. In warmer water, animals need more oxygen to achieve physical activity. But he can not have so much oxygen, which has a lot of oxygen. meaning they were not getting there much.

In other words, as animal creams demand more oxygen, the sea supply collapsed.

In their model, the researchers can do to & # 39; habitat loss measure as species affecting the position of seas that was increasingly challenging. Increasing surface temperature and loss of larger oxygen in areas further from the middle zone. Banning rates were also increased at higher latitudes.

Animals in the tropics have already been used to warmer temperatures and lower oxygen levels before the volcanic volumes moved to the weather, according to the research. As the world was warming, they could move with their habitat.

Sea creatures who loved cold waters and high levels of oxygen were worse: they had no room to go.

"The upper stages where it is cold and oxygen are high – if you need a species that needs to be those types of living, these conditions Disappeared completely from Earth, "said Deutsch.

In fresh seas, the oxygen warmth and loss have been more similar to the poles, researchers said, another analog drag between the movement in a climate of 252 million years ago and what is a & # 39; happening today.

"The study tells us what is at the end of the road if we allow us to keep weather (change). Increasingly, we will grow more and more species; We could lose it, "he said. "That is frightening. The species is not insulting it."
