The ocean keeps gulping up a colossal amount of CO2 from the air, but will it last?
The ocean has proved to be an exceptionally selfless and dependable planetary companion.
With no benefit to itself, Earth's vast sea has gulped up around 30 percent of the carbon dioxide humans emitted into Earth's atmosphere over the last century. Critically, scientists have now confirmed that the ocean in recent decades has continued its steadfast rate of CO2 absorption, rather than letting the potent greenhouse gas further saturate the skies.
Their research, published Thursday in the journal Science, found that between 1994 and 2007, the oceans reliably sucked up about 31 percent of the carbon dioxide produced by humans, even as CO2 concentrations skyrocketed to their highest levels in at least 800,000 years. This means the ocean is now absorbing a significantly larger bulk of carbon, amounting to well over 2 trillion tons each year. Read more...
