Mathematicspredicts a sixth mass extinctionBy2100, oceans may hold enough carbon to launch mass extermination ofspecies in future millennia
Rothmanpredicts that, given the recent rise in carbon dioxide emissions overa relatively short timescale, a sixth extinction will depend onwhether a critical amount of carbon is added to the oceans. Thatamount, he calculates, is about 310 gigatons, which he estimates tobe roughly equivalent to the amount of carbon that human activitieswill have added to the world's oceans by the year 2100.
