The Southern Ocean is a key region for global carbon uptake and is characterized by a strong seasonality with the annual CO<sub>2</sub> uptake being mediated by biological carbon drawdown in summer. Here we show that the contribution of biology to CO<sub>2</sub> uptake will become even more important until 2100. This is the case even if biological production remains unaltered and can be explained by the decreasing buffer capacity of the ocean as its carbon content increases. The same amount of b ...[more]
