I still think that since the Keeling curve is going up, this shows the abilities of the land and oceans to reabsorb the CO2 are currently being overwhelmed.

Assume that 10 units of CO2 are being burned each year. The earth absorbs 2 unit(20%), the ocean absorbs 4 units(40%) and the atmosphere is left with 4 units.

Now double it. Burn 20 units. Let's say the earth absorbs 5 units (25%), the ocean absorbs 9 units (45%) and the atmosphere is left with 6 units.

The total amount of carbon in the atmosphere has increased, meaning that the keeling curve goes up. Yet the ability of the land and oceans to reabsorb CO2 has not been overwhelmed, it has actually increased.

Higher amounts of CO2 in the atmosphere mean an increase in partial pressure. It is entirely possible that this results in an increase in uptake by other systems.
