If uptake capacity is decreasing and CO2 emissions are increasing, which I'm lead to believe is the case, and atmospheric and oceanic CO2 levels are increasing, which I'm also lead to believe the case...

Then I don't understand where you're coming from?

> If uptake capacity is decreasing

I never said that, and I don't think it's true. The timescale I was referring to is the timescale for uptake capacity to respond to a change in CO2 levels. For example, trees grow and reproduce more slowly than CO2 levels have been changing, so the increase in uptake from tree growth and reproduction takes some time to respond to an increase in CO2. But that doesn't mean it never responds. It does; uptake capacity does increase.

Hmmmm, I just assumed global CO2 update capacity is decreasing, but I don't have any evidence I can link to immediately to support that.

This indicates to me I probably need to go away and do some research.

Thanks for bringing this assumption to my attention.
