Carbon Dioxide Emissions May Trigger a Devastating Reflex in the Carbon Cycle, Study Finds

Surpassing a “carbon threshold” could lead to mass extinction. Daniel Rothman, professor of geophysics and co-director of the Lorenz Center in MIT's Department of Earth, Atmospheric and Planetary Sciences, has found that when the rate at which carbon dioxide enters the oceans pushes past a certain threshold - whether as the result of a sudden burst or a slow, steady influx - the Earth may respond with a runaway cascade of chemical feedbacks, leading to extreme ocean acidification that dramatically amplifies the effects of the original trigger.

How's the Carbon Stacking Up? NOAA Says CO2 Has Passed Its Mark

The latest human first has chilling consequences for our species, and all others: for the first time since scientists began tracking global carbon dioxide concentrations in our atmosphere, we have surpassed 400 parts per million worldwide.
