The current
total amounts of carbon in the atmosphere and the ocean surface layer are about 1:1.
Because
the total amount of carbon in the atmosphere is the sum of the natural contributions plus the contribution from anthropogenic sources, the same observation would apply to the graph in the AR5.
The new charts also link regional changes in climate directly to
the total amount of carbon in the atmosphere.
Not exact matches
These experiments all measured how extra CO2
in the
atmosphere affects plant growth, microbial production
of carbon dioxide, and the
total amount of soil
carbon at the end
of the experiment.
Humans do emit only a fraction
of the 750 gigatons
of CO2 that move through the
atmosphere each year, but small changes
in the
total amount can overwhelm so - called
carbon «sinks» such as the ocean, resulting
in important, and cumulative, changes
in the
atmosphere.
Although scientists have measured atmospheric CO2 levels for decades, the current network
of ground stations, observatories, aircraft and other instruments emerged during an era when researchers were trying to answer questions about the
total amount of carbon dioxide
in the
atmosphere.
The kind
of climate we wind up with is largely determined by the
total amount of carbon we emit into the
atmosphere as CO2
in the time before we finally kick the fossil fuel habit (by choice or by virtue
of simply running out).
The
amount of carbon that would need to be removed from the
atmosphere and stabilized
in soils,
in addition to the
amount required to compensate for ongoing emissions, to attain pre-industrial levels is equivalent to approximately one - half
of the
total carbon in all
of Earth's vegetation.
As I've said many times before, my theories lead to the conclusion that it is not the
total amount of CO2
in the
atmosphere that is important, but the proportion
of new hot CO2.If you doubt that, just take a look at the specific heats
of oxygen, nitrogen and
carbon dioxide
«We estimate that the
amount of carbon sequestered
in the growing forests was about 10 to 50 percent
of the
total carbon that would have needed to come out
of the
atmosphere and oceans at that time to account for the observed changes
in carbon dioxide concentrations,» said Nevle, a visiting scholar
in the Department
of Geological and Environmental Sciences at Stanford.
Henry's Law still holds, as the
amount of free CO2
in the water follows the increase
in the
atmosphere, but free CO2 is less than 1 %
of the
total amount of carbon in the oceans surface layer, the bulk are bicarbonates and carbonates, which don't follow Henry's Law, but influence the
amount of free CO2.
If nothing extra is added or substracted (temperature, volcanic vents,... are constant), then the Rin = Rout and nothing happens
in the
atmosphere with the
total amount of carbon / CO2
in the
atmosphere.
Obviously it did to some extent, since an
amount representing under half
of total emitted fossil
carbon remains
in the
atmosphere, but why it didn't take all, or why it took any, are lost
in the details
of the complex ecological interactions involved
in the
carbon cycle.
This implies that there is a linear relationship between the CO2 level and the
total amount of «
carbon»
in the
atmosphere.
And these vast jamborees — some involving more than 10,000 people — haven't even started to discuss how we are going to limit the
total amount of carbon we dump
in the
atmosphere, which is what we actually need to do to avoid dangerous climate change.
The soils
of the world contain more
carbon than the combined
total amounts occurring
in vegetation and the
atmosphere.
In order for biomass to be
carbon neutral, you'd have to actually increase the
amount of carbon being sucked out
of the
atmosphere by forests by an
amount commensurate with the
total net emissions created by chopping down a
carbon sink and then adding a slew
of new emissions by burning wood for energy.
-- If undersea volcanoes emit sufficient
amounts of acids (
in the enormous carbonate buffer masses
of the deep oceans), then the pH
of the oceans could lower somewhat, but that would show up
in a lower
total carbon (DIC: CO2 + - bi-carbonates) content
of the oceans as they release CO2 to the
atmosphere.
«We estimate that the
amount of carbon sequestered
in the growing forests was about 10 to 50 percent
of the
total carbon that would have needed to come out
of the
atmosphere and oceans at that time to account for the observed changes
in carbon dioxide concentrations,» said Richard Nevle, visiting scholar
in the Department
of Geological and Environmental Sciences at Stanford.
