Global warming climate has caused 2 historical disasters of extinction

These were the two events of the late Triassic and the Toarcian period. Turns out, volcanoes did not cause the temperature to drop, on the contrary to strengthen.

In the history of Earth there have been many mass extinctions. And according to a recent study, at least two of them are caused by global warming.

Specifically, there are 2 at the end of the Triassic Period (LTE) and Toarcian Century Event (ETOE) . In the past, both were thought to be related to the massive volcanic event that caused climate change and accelerated the natural extinction rate in the area.

A sharp rise in temperature leads to two extinction events on Earth.

However, things are not entirely like that. The new study shows that mass extinctions in these periods are due to the rapid rise in global temperatures. As a result, the temperature and acidity in the sea water increase sharply, while the oxygen concentration decreases.

"The data show that there is a clear difference in the disaster scale between the warming process in each stage" - quoted in the research report.

It is known that LTE and ETOE took place from 201-18 million years ago. In particular, ETOE is considered the second largest extinction event in the history of Earth related to marine life.

To get the results, experts have modeled extinctions at both events, based on data on aquatic species globally. In both events, extinct creatures are due to the inability to adapt to the new climate - " selective extinction " or " selective extinction ."

The climate at this time has been extremely extreme.

Accordingly, the climate at this time has changed extremely extreme. The temperature heats up so fast, the oxygen in the water drops, and the acidified sea water pushes the species into extermination. At the same time, coral reefs collapse.

"Although there are differences in conditions, number of species, global warming and habitat, both basically have the same trend of extinction" - quoted in the research report.

"At both events, marine species - including hunting groups, luminescent species at the bottom are the most affected individuals."

Volcanic eruptions did not reduce the temperature during this period.Everything turned out to be the opposite.

But why care about this study?

Because, it reveals part of the story that will happen to us today, when the problem of global warming is getting sore.

At present, the coral at Australia's " Great Barrier" is bleached because the acidity in the sea water rises. Marine organisms are increasingly narrowing their living environment. There are even sea areas that are considered "dead sea", because the oxygen level in it is 0.

Coral bleached at.

With this study, science can at least know what will be the most affected and easily extinct creatures, and from there there will be more suitable ones.
