We release carbon dioxide from nine to 10 times faster than the global warming effect 56 million years ago. According to a new study, Earth can be 140 years away from a similar climate change event that has triggered a great downturn. (The Pixabay )
How long do people have up to a serious global warming event that is similar to the 56 million years ago? A new study says, at the rate of carbon emissions today, it could be as early as 140 years.
According to a new study, the concentration of carbon dioxide in the Earth's atmosphere rises faster than it did at any time during the time of dinosaurs. In fact, the study found that men actually pumped carbon dioxide to the air at a rate that is nine to 10 times more than 56 million years ago.
The geophysician and teacher Gabriel Bowen, who reviewed the study for the magazine, said that today's carbon emissions rates are not even in the context of the Paleocene-Eocene thermal maximum event ( PETM), the global warming event of 56 million years ago which caused mass disappearance in the oceans and rapid evolution in the continents.
According to the study, given the rate of carbon emissions today, a PETM-like warming event may occur on the planet as little as 140 years or just five generations. Accordingly, the temperature 9 to 14 degrees Fahrenheit rose (5 to 8 degrees Celsius), animals on land and at sea were killed, and took over 150,000 years before the planet returned.
Simply, though PETM has been used in the past as a benchmark for modern climate change, the latest findings reveal that it could happen sooner than expected. Although PETM was not the hottest ever the Earth has been, it is the hottest since the dinosaurs have been deleted 66 million years ago.
"You and me will not be here in 2159, but it's only about four generations. When you start to think about your children and your grandchildren and grandchildren and your grandchildren , you're there, "said lead author, Professor Philip D. Gingerich, from the University of Michigan.
The study is published in the magazine Paleoceography and Paleocystatology.
