The terrible cause behind the Great Death – and not good for us

Scientists think they understand the dominating dominos that led to the greatest mass extinction of the world, and they are concerned that human-induced climate change is undergoing an uncertain path to the planet.

Approximately 250 million years ago, about 90 percent of marine life and 70 percent of the land life were destroyed in what is now called the Great Death.

Scientists have long been speculating that massive volcanic eruptions have triggered a catastrophic event, but those who worked were still a little blurry.

Not the lava itself. In a recent study on Thursday's magazine, he used complex computer simulations to elicit events that occurred after the volcano erupted: it caused the ocean's temperature to rise to about 11 degrees centigrade.

This hot oxygen opened water caused a loss of sea mass, especially away from the equator.

After the volcanoes exploded, the level of carbon dioxide, which caused heat to hold, rose to more than 12 times today. This study was conducted by Justin Penn, a researcher on earth science at the University of Washington.

Penn said that when the hot arm warmed up like a flat box, the water had lost oxygen.

Scientists thought that dozens of modern species were exposed to warm, oxygen-free water and helped them understand what had happened in the past.

One of the keys to the study is that more species have died in the equator. Penn is due to the fact that tropical species are more accustomed to low oxygen levels.

. This puts our future in the category of contestants for the real disaster, milyon he said, while people are not warming the Earth close to what happened 250 million years ago. Washington University.

Mr. Deutsch said that old immortality "is almost exactly what happened at the end of the road." "We are really doing the same thing to Earth's climate and oceans."

In the study, if the carbon dioxide emissions that cut the heat continue at the current levels, it is estimated that by 2300 the world will experience 35 to 50 percent of the exhaustion level seen in the Great Death.

Paul Wignall, a paleontologist from Leeds University, said the global warming scenario does not foresee a warming of 20 degrees over the next few centuries, so it could be a thousand years away.

However, Wignall was not part of the study, since even 10 percent of an event as bad as the Great Death would be horrible.

Other external scientists have said the study has taken a terrible look at the possible future of the Earth.

In an e-mail, scientist David Bottjer of the University of Southern California said:, Because we wet the world at a fast pace, the results of this work can prove to be very useful in understanding what will happen in future oceans.
