The Earth has already suffered five mass extinctions in the last 540 million years, all of them as a result of alterations in the normal cycle of carbon through the atmosphere and the oceans.
A team of scientists from the Massachusets Institute of Technology (MIT) assures that a sixth mass extinction is approaching that will exterminate the species of living beings on the entire planet.
Daniel Rothman, a professor of geophysics in the MIT Department of Atmospheric and Planetary Sciences and co-director of the MIT Lorenz Center, has analyzed significant changes in the carbon cycle over the past 540 million years and developed a mathematical formula based on physical principles. related to the functioning of the carbon cycle thatit basically depends on the balance between photosynthesis and respiration.The formula relates the critical rate and the magnitude of the change in the carbon cycle to the time scale that separates a fast change from a slow change.
When will it happen?
According to the projections of the mathematical formula used, when human beings are “capable” of placing another 310 gigatons of carbon in the ocean. The most recent report from the Intergovernmental Panel on Climate Change indicates that it will occur by the year 2100, when the carbon cycle will be close to or well above the threshold of catastrophe.
Does this mean that in 2100 the species will begin to fall and die as in an apocalypse? Not at all. As Rothman explains and as in the mass extinctions of the past, “it is the beginning of an event that could take 10,000 years to be considered a total disaster”.
Since then, "we enter unfamiliar terrainRothman says.
