What is it about?

This is an idealized study to quantify the isolated effect of atmospheric CO2 rise on the dissolved inorganic carbon content of the global ocean surface, assuming all else constant.

Why is it important?

From the 1960s to 2000s, the air−sea re-equilibration implied ocean surface anthropogenic CO2 accumulation rate may have increased by 46% due to the accelerated atmospheric CO2 rise. However, the chemical buffering capacity within the ocean surface may have declined by 16% during the same period.

Perspectives

The surface ocean plays a non-negligible role in the mitigation of atmospheric CO2 rise, although the net storage in this active reservoir is subject to a short residence time of one to several years.
