By 2100, the oceans can accumulate enough for the death of living beings the amount of carbon.
Scientists from mit have estimated that by 2100 the oceans can accumulate enough for the death of living beings the amount of carbon.
The researchers analyzed changes in the carbon cycle over the past 540 million years. They identified the valid values, at exceeding of which the carbon cycle became unstable, and living creatures died. Researchers believe that mass extinction will occur if the carbon cycle will change faster, than he will be able to adapt to ecosystems.
Given the recent growth in carbon emissions in a relatively short period of time, the fate of the sixth mass extinction will depend on whether accumulate a critical amount of carbon in the ocean, said study author Daniel Rothman.
The critical number, as scientists estimate is 310 gigatons. This is equivalent to the amount of carbon that experts suggest will occur due to human activities in the oceans in 2100.
Does this mean that a mass extinction will take place at the turn of the century? For such environmental disasters will take some time, about 10 thousand years. However, if you do not stop the process of accumulation of carbon in the ocean, the sixth mass extinction could happen sooner – said Rothman.
