| The increase of atmospheric CO2 (ref. (1)) has been predicted to impact the seasonal cycle of inorganic carbon in the global ocean(2,3), yet the observational evidence to verify this prediction has been missing. Here, using an observation-based product of the oceanic partial pressure of CO2 (p(CO2)) covering the past 34 years, we find that the winter-to-summer difference of the p(CO2) has increased on average by 2.2 +/- 0.4 mu atm per decade from 1982 to 2015 poleward of 10 degrees latitude. This is largely in agreement with the trend expected from thermodynamic considerations. Most of the increase stems from the seasonality of the drivers acting on an increasing oceanic p(CO2) caused by the uptake of anthropogenic CO2 from the atmosphere. In the high... |
