CO2 During Its Most the Highest Level In 3 Million Years
The study found that Ice Age onset, and the start of the glacial cycles from cold to hot and back, was mainly triggered by a reduction of CO2 levels. The degrees of the greenhouse gas carbon dioxide in the atmosphere is higher today than ever before in the past 3 million years, based on a study. For the very first time, scientists from the Potsdam Institute for Climate Impact Research in Germany triumphed to do a PC simulation that matches the ocean floor sediment information of climate change during this period of time.
The study found that Ice Age onset, and the start of the glacial cycles from cold to hot and back, was mainly triggered by a decrease in levels. Today it increases ease in greenhouse gases due to the burning of fossil fuels that’s changing our planet, in accordance with the study published in the journal Science Advances. Global mean temperatures never exceeded pre-industrial levels by more than 2 degrees Celsius in the past 3 million years, the study shows. The current climate policy in action, if continued, could surpass the 2°, restrict already in the next 50 years, researchers stated.
We know from the research of sediment on the bottom of our seas about previous ocean temperatures and ice volume, but so far the use of CO2 changes in forming the glacial cycles has been completely understood, stated Matteo Willeit of the Potsdam Institute for Climate Impact Research, leads writer. It’s a breakthrough that we may now show in computer simulations that changes in CO2 levels have been a principal catalyst of the ice ages, together with variations of how the Earth’s orbit around the sun, the so called Milankovitch cycles. He explained.
