you actually didn't read the source material that's why you made the response you did, so you have no idea how I came to that conclusion
Hopefully the reader is paying attention to the extent that they will see that this +3 gigatons is about half the amount initially introduced into the atmosphere due to fossil fuel combustion, given as 5.5 gigatons in this chart and 6 gigatons in the Raven & Berg chart

and we add, get this, 3 gigatons!!! yup 3 gigatons of a total 40,250 gigatons
The total amount of CO2 residing in the atmosphere is given as 750 gigatons
Carbon Dioxide (CO2) molar mass: 44.0095 g/mole = c
Earth's atmosphere: 5,148,000 gigatonnes (Gt) = a
Mean molar mass of the atmosphere: 28.97g/mole = b
Carbon Dioxide (CO2) molar mass: 44.0095 g/mole = c
Atmospheric CO2 ppm, 2017 annual mean: 404.92ppm = d
Atmospheric CO2 mass, 2017 annual mean (a * (c / b) * d): 3,166.6911 Gt
If you divide 750 gigatonnes of carbon by 27.3%, you come up with 2747 gigatonnes of carbon dioxide
Scientists estimate that humans can pour roughly 565 more gigatons of carbon dioxide into the atmosphere by midcentury and still have some reasonable hope of staying below two degrees. ("Reasonable," in this case, means four chances in five, or somewhat worse odds than playing Russian roulette with a six-shooter.)
The Third Number: 2,795 Gigatons
This number is the scariest of all – one that, for the first time, meshes the political and scientific dimensions of our dilemma. It was highlighted last summer by the Carbon Tracker Initiative, a team of London financial analysts and environmentalists who published a report in an effort to educate investors about the possible risks that climate change poses to their stock portfolios. The number describes the amount of carbon already contained in the proven coal and oil and gas reserves of the fossil-fuel companies, and the countries (think Venezuela or Kuwait) that act like fossil-fuel companies. In short, it's the fossil fuel we're currently planning to burn. And the key point is that this new number – 2,795 – is higher than 565. Five times higher.
Carbon is a chemical element, like hydrogen, oxygen, lead or any of the others in the periodic table.
Carbon is a very abundant element. It exists in pure or nearly pure forms – such as diamonds and graphite – but can also combine with other elements to form molecules. These carbon-based molecules are the basic building blocks of humans, animals, plants, trees and soils. Some greenhouse gases, such as CO2 and methane, also consist of carbon-based molecules, as do fossil fuels, which are largely made up of hydrocarbons (molecules consisting of hydrogen and carbon).
In the context of climate change, "carbon" is commonly used as a shorthand for carbon dioxide, the most important greenhouse gas released by humans. Technically, however, this isn't accurate. Carbon only becomes carbon dioxide when each atom of carbon joins with two atoms of oxygen (hence the chemical formula of carbon dioxide, CO2).
This shorthand can sometimes cause confusion, because although "a tonne of carbon" will often be used to mean "a tonne of CO2", in a scientific context the same phrase could mean "CO2 containing a tonne of carbon" (which is a much smaller amount, as oxygen accounts for most of the weight of each CO2 molecule).
The term carbon also crops up in the phrase carbon footprint, which describes the total amount of greenhouse gases released as the result of a given activity. In this context, "a tonne of carbon" may mean something else still: "a mix of greenhouse gases with a combined warming impact equivalent to that of a tonne of CO2".

come on are you going to send me some NASA links or something similar that actually put up the numbers you did above?
like we have several thousand gigatons of C02 in the atmosphere and of course carbon isn't c02 it's just a part of C02

Problem 3 - If a concentration of 127 ppm of carbon dioxide in the atmosphere equals
a total of 1,000 gigatons of carbon dioxide (1,000 billion tons), about what was the total
mass of carbon dioxide gas in 2005? Answer: (379/127) x 1,000 gigatons = 2,984
gigatons, or to 3 significant figures, 2,980 gigatons.
Earth's atmosphere: 5,148,000 gigatonnes (Gt) = a
Mean molar mass of the atmosphere: 28.97g/mole = b
Carbon Dioxide (CO2) molar mass: 44.0095 g/mole = c
Atmospheric CO2 ppm, 2017 annual mean: 406.53ppm = d
Atmospheric CO2 mass, 2017 annual mean (a * (c / b) * d): 3,179.2822 Gt
There we are, all 5 items in the equation accounted for: Earth's atmosphere: 5,148,000 gigatonnes (Gt) = a Mean molar mass of the atmosphere: 28.97g/mole = b Carbon Dioxide (CO2) molar mass: 44.0095 g/mole = c Atmospheric CO2 ppm, 2017 annual mean: 406.53ppm = d Atmospheric CO2 mass, 2017 annual mean (a * (c / b) * d): 3,179.2822 Gt
It currently constitutes about 0.041% by volume of the atmosphere, (equal to 410 ppm) [14][15][16][17][18] which corresponds to approximately 3200 gigatons of CO2, containing approximately 870 gigatons of carbon.

look do us all a favor post a link to the amount of c02 in the atmosphere in gigatons and stop with the technical breakdown trying to prove how smart you are
show us the link with just the measurement in gigatons
