Seeing this as a baseline, positive CO2 feedback from temperature changes, or a running out of capacity for greater uptake from CO2 accumulation, would be seen as adding more CO2 to the air in addition to anthropogenic releases, but it would have to surpass some level before it would result in a total atmospheric accumulation of CO2 greater than anthropogenic emissions (first, as a rate, and later, cummulative change).
