Less than 150 years ago, the Earth's climate was able to heat up about 56 million years ago, crocodiles swarmed by the Arctic and parts of the equator for unhealthy creatures according to a new climate change model.
Research published Nature Geoscience Models that measure how high CO2 levels measure: the stratosphere causes the formation of clouds – it accounts for about 20 percent of the subtropical ocean's low and flat traces and about 30 percent of the sun's light.
After two decades of supercomputer calculations, researchers found a sudden transition to the 1200 km of simulated CO2 in the atmosphere. Cloud-strategy broke and disappeared, leaving blue sky.
This would cause sudden fluctuations in temperature, as the heat emitted by the ocean would be reflected as follows.
Stratocumulus cloud loss would be added to 8C additional warming over the expected amount, the researchers concluded.
In this place, the Earth would have a warm 14C above the industrial precinct.
That's a great deal. Remember that the rise of temperature 4C is "at the end of human civilization in the current form".
This alone would see rising sea levels, destroying coral reefs in the world, massive loss of animal species and catastrophic extreme weather events.
It is difficult to imagine what would happen if the temperature 8C jumped over the already warming.
Perhaps the best guide Earth's temperature was 56 million years ago, when sea water was in the tropics of the 40C and crocodiles were developing in the herds of living beings.
When could this happen?
The concentration of CO 2 in the atmosphere at 1200 ppm could range from 100 to 150 years, if we continue to keep fossil fuels from fossil fuels in the current rate, according to research by Tapio Schneider at the California Institute of Technology.
"I do not think it would come anywhere like that," he said in a press release.
"I believe that I expect and the technological changes are expected to slow carbon emissions, so high CO2 concentrations do not really reach us.
Mark Howden, director of the Climate Change Institute at the Australian National University, said Hack the world can exceed 1200ppm if countries do not meet the targets for emission reduction commitments committed by the Paris Agreement.
"I want to say what these studies mean, we do not want to just go," he said.
"Potential external feedback beyond our control is very disturbing."
"We want to keep carbon dioxide levels below those levels."
Why do we only now study?
So far, climate modeling has been struggling to predict the temperature rise and cloud formation, simply because the cloud is very hard.
The researchers solved this problem, using a powerful supercomputer and modeling small patches of ocean and sea clouds.
The study also explains why, now, 56 million years ago, the planet had a dramatic warming. The temperatures of the Paleocene-Eocene Thermal Maximum were believed to be more than just climatic models, depending on the CO2 concentration and the plant's coverage factors.
"This is the first exploration of this particular problem and it is very good to prove the ability of these models to function, so that they can be imagined through these patterns of clouds," says Howden Professor. Hack.
"I think it's a very important breakthrough in science."
