As a result of warm climate, the vast majority of Earth's history came, scientists have applied.
About 252 million years ago – almost 200 million years ago before dinosaurs were destroyed by asteroid – around 96% of marine life was deleted in the Great Dying.
A correct case was debated for decades, but new research from the US has been published; mark a branch at global warming.
Scientists in the universities of Washington and Stanford were running modules of the ancient Earth, symbolize the effects of its & # 39; warming up on the planet.
They once found sea temperatures around 10degC higher than today, the oceans lost 80% of their oxygen. This suffers enough, but the teas are higher than; Increasing animal metabolism – this means they need more oxygen than ever before, despite their & # 39; Most of it is going out of the water.
"The name of this killing device, climate warming and loss of oxygen, is the geological pattern that is expected to detect and then find in the fossils," said author Justin Penn, a student at the University of Washington University in geography.
"The agreement between both shows that this method of climate warming and loss of oxygen is a major cause of extinction."
These were the creatures that were; Long lived from the tropics the most prevalent in the symbols. This was linked to the paleontological record.
The tropical metabolism had been seasonal, occasionally warm, warm enough, as well as moving away from the tropics and its; obtaining the same contracts elsewhere, "said co-author Curtis Deutsch, a professor of scholarly in Washington.
"But if the organism has changed for a cold environment, oxygen, these conditions have not stopped in the deficient hills."
The sciences say at the current level of uptake, we currently have around 20 per cent of the way to similar situations at the end of this century. By 2300, we can be a half way there.
"This study shows that there is potential for extinction arising from similar anthropogenic climate change equipment," said Mr Penn.
Earlier this week, scientists said that this year's carbon content is demanded to a high level, up 2.7 per cent in 2017. The United States is a? Most people have the most impact, but China is spread the widest.
The inspection was published on Friday (USA) in a magazine ScienceSouth Westerly
