Scientists have discovered that if people do not control greenhouse gas emissions, the risk will be magnified by a situation similar to that that occurred 50 million years ago.
The new study revealed that human activity was driving the climate to reverse long-term cooling, with a phase similar to that of the Eosin era, when the planet was warm and ice-free.
According to scientists, in about 20 years, the climate could return to a phase similar to that of the Middle Pleiocene, there are more than 3 million years. By 2150, the climate could return to its level of 50 million years ago.
According to the new study published in the Proceedings of the National Academy of Sciences, the man-made state coup began about two centuries ago, accelerating the observed changes.
"We are moving towards very dramatic changes within a very short time," said lead author Kevin Burke, who led the study while he was a graduate student at University of Wisconsin-Madison.
In this study, researchers examined data on the geological past to see how different ages intersect with future climate predictions.
Looking at future climate scenarios, the results showed that the Earth's climate could be similar to that of the Middle Pleiocene period, when temperatures were more than 1.8 to 3.6 ° C, warmer than normal. Today, by 2030. Or 2040. If emissions continue, the Earth's climate will begin to resemble the Eosin era, around 2100.
By the year 2150, this situation will be strengthened worldwide and the team also found that new climatic conditions, never encountered before, could occur, especially in East and South Asia. -It is in Northern Australia and on the coasts of the Americas.
