Let's question where it goes as well.
Say for example, we take the 5% as a given value as "actual" CO2 output and say for example this 5% is the equilibrium that Phanuthier speaks of. But consider my earlier post where records show they're already the highest they've ever been in 650000 years.
If the 5% is exceeded then there's the potential for the whole show to go out of equilibrium.
e.g. ocean acidification -research shows/suggests that CO2 uptake by oceans halved between 1995-2005. Man made or otherwise I don't know but I'm going .
Fact is the oceans are getting more acidic (as kevman says chemistry doesn't discriminate) killing off carbon fixing algae and phytoplankton. . The capacity of surface waters to take up anthropogenic CO2 is decreasing as CO2 levels increase. That = loss of uptake. The 5% and increasing can't go anywhere.
Take the same principle and apply it to a tropical forest. Deforestation = reduced carbon uptake for the purpose of increased carbon production.
Consider the warming process also and a positive feedback loop. Snow/icecaps = white = good reflector. icecaps smaller = less reflection = more absorbtion = more heat retention.
Consider the Methane (x23 the warming potential of CO2) locked under the tundra and permafrost melting (which is happening here and in Russia). The loop accelerates.
The problem is in this measurement; ocean acidification and its depleted ability to uptake CO2 , methane release from the artic tundra, and the increasingly depleted reflection of the sun's rays aren't measured as anthropogenic outputs.
What I'm saying is the CO2 output is going up, it's having an effect/affect impact on others systems ability to uptake it, it has nowhere to go but up.
