Researchers warn and spread terrifying information about the future of life on Earth
Atmospheric carbon dioxide (CO2) is the most responsible for warming the climate, at its highest level in 3 million years, necessitating a rise in the temperature of the planet and ocean level, according to the warnings from researchers.
Scientists believed that the current level of CO2, which is just over 400 ppm, is not higher than that which prevailed 800, 000 years ago, a period punctuated by cold and free waves in the planet, but that an underground ice and sediment samples extracted from the coldest site on the planet revealed that the threshold of 400 mow Million has been surpassed last time 3 million years ago, during the Bossing era.
The temperature was three to four degrees Celsius and the trees were growing in Antarctica and the ocean level was about 15 meters higher.
These analysis were enhanced by a new climate model developed by the Potsdam L Praised for the Impact Research Research Institute (Pi Kai).
"The late Bossing is relatively close to our time in terms of carbon dioxide levels," said Matthieu Vila it, a researcher at the Institute and the main curator of the study, whose results were published this week.
"Our models lead us to think that it was not from an icy cycle or a dense ice cap in the northern hemisphere, as CO2 levels were too high and the climate is so hot," he said.
In 2015, the international community concluded the Paris Agreement on climate, which states that warming should be limited to 2 degrees Celsius or 1.5 degrees, if possible in relation to the Prue-industrial era, but in 2017, greenhouse gas emissions were the highest in the history of mankind, and if the world simply made commitments Agreed in Paris, the temperature will rise at a rate of 3 degrees Celsius.
Researchers gathered this week in London stressed the importance of extracting lessons from the plainsong, with the Earth, which has risen to one degree relative to the Prue-industrial era, today under the brunt of the climatic imbalance with its accompanying floods and droughts.
Researchers estimate that the atmosphere has previously seen CO2 levels significantly higher than 400 ppm, but it took millions of years to accumulate gas.
Emissions from industrial activities have increased carbon dioxide levels by more than 40% in the course of a century and a half.
