Carbon dioxide from burning fuels and forests is flowing in twice as fast as it is being absorbed by plants and the ocean, and some of those «sinks» are in fact getting saturated, it appears, meaning that the «drain» is clogging a bit.
They're talking about the time it takes for half the CO2 in the air to be absorbed by sinks like the ocean.
Of the emitted CO2 from burning of fossil fuels, about 50 % is absorbed by the ocean and terrestrial carbon sinks at present.
For example: 1) plants giving off net CO2 in hot conditions (r / t aborbing)-- see: http://www.climateark.org/articles/reader.asp?linkid=46488 2) plants dying out due to heat & drought & wild fires enhanced by GW (reducing or cutting short their uptake of CO2 & releasing CO2 in the process) 3) ocean methane clathrates melting, giving off methane 4) permafrost melting & giving off methane & CO2 5) ice & snow melting, uncovering dark surfaces that absorb more heat 6) the warming slowing the thermohaline ocean conveyor & its up - churning of nutrients — reducing marine plant life & that carbon sink.
It is postulated that the ocean is a major carbon sink, absorbing most of the missing 50 percent of the co2.
The critical factor is probably the rate of increase in heat content of the Southern Ocean, and the ability of the massive heat sink of Antarctica to absorb this.
Pacala and Socolow further theorize that advancing technology would allow for annual carbon emissions to be cut to 2 billion tons by 2104, a level that can be absorbed by natural carbon sinks in land and oceans.
Isn't it evident that as the surface warms the ocean heat sink will tend to absorb more heat, and that if the surface cools then the ocean releases heat?
This, it says, triggered droughts in tropical regions and reduced the capacity of «sinks» like forests, vegetation and the oceans to absorb CO2.
The mass balance and d13C balance shows that vegetation as sink is not large enough to absorb all human CO2 if the oceans are a source and ice cores show that CO2 and temperature go to a (surprisingly linear) new equilibrium for every change in temperature level, not a sustained increase or decrease.
Instead, ocean life absorbs CO2 during photosynthesis and, while most of the gas escapes within about a year, some of it is transported down into the deep ocean via dead plants, body parts, faeces, and other sinking materials.
Carbon sinks (ecosystems which absorb CO2, like oceans and forests) respond to climate change in two different ways.
However, many carbon sinks (e.g. the ocean) become less effective at absorbing carbon dioxide at higher concentrations of dissolved CO2.
Cold water in clouds is the nearest sink that absorbs the CO2 that is outgassed from the surface of the ocean.
Update Dec. 12, 10:55: The deal also calls for balancing out carbon emissions caused by humans with those that can be absorbed back in by sinks (such as trees and oceans).
Oceans are the biggest sink right now — we have reasonable numbers on how much they're absorbing through pH measures and satellite observation of chlorophyll production.
Nearly 1/3 of the 8 GtC / year is absorbed by just forests worldwide currently http://www.csiro.au/news/Forests-absorb-one-third-our-fossil-fuel-emissions.html Which leaves a miserly 1.333 GtC / year for the rest of the biological sinks (and oceans) to absorb leaving the atmosphere CO2 at 4 GtC / year increase = the CO2 levels are still to low and this shows the CO2 global pathway as definitely unknown.
Interestingly enough, if you correct that first graph in this post for seasonal effects (you know, plants growing in the spring, dying off in the fall), and the fact that about half (by mass balance) of our emissions are absorbed by ocean and plant sinks, those two lines will track each other very well.
That gives what is absorbed in the oceans, again with large margins of error, but a real sink.
The oceans are acting as a heat sink for rising temperatures and have absorbed about one - third of the carbon dioxide produced by human activities.
Furthermore, they found «increasing evidence (P = 0.89) for a long - term (50 - year) increase in the airborne fraction (AF) of CO2 emissions, implying a decline in the efficiency of CO2 sinks on land and oceans in absorbing anthropogenic emissions.»
This is a fortuitous thing, for if there was not this alteration of the energy flow, with the oceans absorbing more heat being the excellent heat sink they are, we'd have a much faster warming troposphere as greenhouse gases increase.

It is counterintuitive for ACO2 to be so different from natural CO2 to the extent that there is no or little capacity for sinks to reabsorb the human emissions; it is also problematic that there should be a situation where temperatures have slightly increased and yet the ocean remains a net absorber and not emitter of CO2.
The oceans are by far the largest heat sink for the Earth, absorbing the vast majority of extra heat trapped in the system by increasing concentrations of greenhouse gases.
We've discussed Sabine before; consider; if the oceans mop up 48 % of human emissions; what do the other sinks absorb?
