Faster sea floor spreading, presumably associated with more volcanic activity at subduction zones, and / or other increases in volcanic activity or geologic outgassing, or faster oxidation of exposed fossil organic C (as in shales)-- greater geologic CO2 emissions (I think another way of looking at the inorganic part is that any given region of sea floor has less time to accumulate carbonate minerals from chemical weathering, so that C reservoir could shrink while others, including the atmosphere, can grow).
While news journalists and internet bloggers are busy headlining scary stories invoking the presumed causal link between anthropogenic CO2 emissions and floods and droughts and global warming, robust scientific evidence of naturally - forced climate change has continued to rapidly accumulate.
The manmade emissions fueling global warming are accumulating so quickly in the atmosphere that climate change could spiral out of control before humanity can take measures drastic enough to cool the earth's fever, many climate scientists say.
As the word «accumulated» implies, atmospheric CO2 concentration at any point in time is the result of * past emissions *, and since we don't have a time machine or a magic wand to change the past, people in the real world have to deal with * future emissions *.
Thus, at that point in the future, a lessor volume of accumulated GHGs in the atmosphere would mean a global climate that is not as warm as the global climate would have been had we not emitted fewer GHG emissions now.

Ideas that we should increase aerosol emissions to counteract global warming have been described as a «Faustian bargain» because that would imply an ever increasing amount of emissions in order to match the accumulated GHG in the atmosphere, with ever increasing monetary and health costs.
Perhaps no surplus carbon sink exists at all to absorb the emissions caused by burning of fossil fuels accumulated in the earth over millions of years.
Rate of percentage annual growth for carbon dioxide has certainly increased since the beginning of the 21st century, but this should result in a significant change in the rate of warming any more quickly than the differences between emission scenarios would, and there (according to the models) the differences aren't significant for the first thirty - some years but progressively become more pronounced from then on — given the cummulative effects of accumulated carbon dioxide.
That is because accumulating observations and analysis pointing to the causes and consequences of global warming merely delineate the problem, including areas of persistent uncertainty, uneven exposure to risk and uneven responsibility for emissions of greenhouse gases.

Although emissions from developing countries now dominate, the industrial countries set the world on its global warming path with over a century's worth of CO2 emissions that have accumulated in the atmosphere.
On the other hand, the correlation between accumulated emissions and accumulation of CO2 in the atmosphere is much better: it is a near fit over the last 100 + years (60 years of ice core data, near 50 years of MLO data).
And according to emissions specialists like the Tyndall Centre's Kevin Anderson (as well as others), so much carbon has been allowed to accumulate in the atmosphere over the past two decades that now our only hope of keeping warming below the internationally agreed - upon target of 2 degrees Celsius is for wealthy countries to cut their emissions by somewhere in the neighborhood of 8 — 10 percent a year.27 The «free» market simply can not accomplish this task.
Global temperature change can in turn be linked both to concentrations of atmospheric carbon dioxide (Table 1) and to accumulated carbon emissions (Figure 1).»
Second, cumulative emissions are particularly important, because it is the accumulated stock of GHGs in the atmosphere that cause climate change.
Elsewhere, I cited as an example an abrupt warming from massive release of permafrost methane precipitated by the gradually accumulating temperature increase from further CO2 emissions.
If those emissions had simply accumulated in the air, the concentration of carbon dioxide would have increased from 280 parts per million (ppm), as it was before the Industrial Revolution, to about 550 ppm today.
The burning of tropical peatlands is so significant for greenhouse gas emissions because these areas store some of the highest quantities of carbon on Earth, accumulated over thousands of years.
Over the past decade, aerosol emissions (which cause cooling by blocking sunlight) have risen, solar activity has been low, there has been a preponderance of La Niña events (which also cause short - term surface cooling), and heat has accumulated in the deep oceans.
Alas, I believe the preponderance of evidence strongly supports the claim that anthropogenic emissions are having an effect on the global climate, and that effect will increase as greenhouse gases accumulate in the atmosphere.
As time goes on, the rate of burning in the power plant stays the same, but the CO2 accumulates, so by the end of the year, the greenhouse gases will be heating the Earth much more than the direct emissions from the power plant.»
IPCC scientists assume that human CO2 emissions will continue to accumulate in the atmosphere, remaining anywhere from hundreds to thousands of years.
If all Joules contribute equally, then each of the 240 W / m ^ 2 of accumulated forcing must also contributes 4.3 W / m ^ 2 to surface emissions adding up to over 1000 W / m ^ 2 corresponding to an average surface temperature close to the boiling point of water.
Given that all Joules are equivalent and all 240 W / m ^ 2 of accumulated forcing from the Sun must on average contribute equally to the emissions of the surface, each W / m ^ 2 contributes about 1.6 W / m ^ 2 to the surface emissions where the next 1.6 W / m ^ 2 of emissions from another W / m ^ 2 of forcing would arise from a surface temperature increase from 288K to 288.3 K.

So there is another reason to believe that while humans certainly ARE adding CO2 to the atmosphere, it isn't the primary component (we already know it isn't the primary component because the atmosphere is accumulating CO2 at a much faster rate than humans add each year) because while human emissions have been rising nearly exponentially, atmospheric CO2 has been rising linearly and that rate of rise did not change when global human CO2 emissions fell in absolute terms (tons of CO2 emitted to atmosphere fell in 2009, rate of increase of atmospheric CO2 unchanged).
The residual, which accumulates to fo rm the trend, provides a record of net emission.
