The Great Dying: Hot Ocean Water May Be The Cause Of Ancient Mass Extinction


According to the scientists’ latest discovery and research, it seems that the cause which led to the Earth’s largest mass extinction has been found and it’s pretty similar to what the humanity is going through today.

About 250 million years ago, about 90% of the sea life and 70% of the land life went extinct, and the process is called today The Great Dying.

Experts and scientists have been speculating for a really long time all the potential reasons that could have led to such a thing.

All kinds of theories were involved such as massive volcanic outbursts and more. But it looks like it was not the lava itself to blame.

Now, a new study that got published in the journal Science made use of really complex computer simulations to plot out what really happened after the volcanoes blew.

This seems to have led to the ocean temperatures rising with about 11 degrees Celsius, and this triggered the starving of the seawater of oxygen.

Hot oxygen-starved waters caused marine life’s death

Then, the hot oxygen-starved water caused the mass marine extinction.

After the volcanoes blew, the level of carbon dioxide soared to a level more than 12 times what it is these days, according to the study’s lead author Justin Penn, an Earth sciences researcher at the University of Washington.

Water loses oxygen when it becomes warm, much like a warm can of cola goes flat, Penn said.

Experts have analyzed dozens of modern species just to see what happens to them while they’re in warmer water starved of oxygen and this helped them understand the past extinction.

While humans aren’t warming the Earth anywhere close to as much as what happened naturally 250 million years ago, “this puts our future into the category of contenders for true catastrophe,” said study co-author Curtis Deutsch, an Earth scientist at the University of Washington.

The ancient die-off “shows almost exactly what lies at the end of the road we’re on,” Deutsch said. “We’re really doing the same thing to Earth’s climate and oceans.”
