The study, which was completed with support from NASA and the National Science Foundation, also notes that even though humans have only been pumping carbon into the oceans for hundreds of years rather than the thousands of years it took for volcanic eruptions and other events to bring about other extinctions, the result will likely be the same.
“Once we’re over the threshold, how we got there may not matter,” Rothman told MIT News. “Once you get over it, you’re dealing with how the Earth works, and it goes on its own ride.”
Other scientists said the study, which will be published this week in the Proceedings of the National Academy of Sciences, represents a clear call for immediate action to drastically reduce the amount of carbon that is being pumped into the world’s oceans. Climate action groups and grassroots movements have long called on governments to impose a moratorium on fossil fuel drilling, which pumps about a billion metric tons of carbon into the atmosphere every year.
