Scientists from the Deep Carbon Observatory (DCO) venture have gone through 10 years evaluating the "reservoirs and fluxes" of the chemical element.
As such, they worked out where carbon is held and in what structure, and how it moves through the Earth system.
The findings will help comprehend the cutoff points of life on our planet and in the forecasting of volcanic emissions.
"This work really came out of the realisation that much of the carbon that we are concerned about for climate change is only a tiny fraction of our planet's carbon. More than 90% of it is actually in the interior of the Earth – in the crust, in the mantle and the core," said Prof Marie Edmonds from Cambridge University, UK.
"Very little was known about its form, how much there was, and how mobile it is. And, obviously, this all has huge importance for both the climate of the Earth, but also the habitability of our surface environment," the DCO partner disclosed to BBC News.
The accounting was a painstaking procedure that included checking gas emissions from major volcanoes and analyzing the deep-sea muds that are drawn, or subducted, into the Earth's inside at structural plate limits.
Using lab trials and models, the group was then ready to reproduce the possible stores and streams of carbon.
Only two-tenths of 1% of Earth's absolute carbon – around 43,500 billion tons – is made a decision to be over the planet's surface, in the seas, ashore, and in the environment. Everything else is in the profound store, with 66% of the all out contained inside the center.
In an interesting activity, the DCO endeavored to portray how this stock has changed through time. Working with the University of Sydney, it has remade the historical backdrop of plate tectonics – to basically replay the movie of the Earth's inward operations.
This uncovered the planet's carbon spending plan through a significant part of the most recent billion years has been in a generally unfaltering state. Put another way, the carbon that has been drawn down into the Earth's inside is generally equivalent to what has been outgassed to the air through any semblance of volcanoes.
From time to time, be that as it may, there have been major disastrous irritations in this cycle.
These disturbances were the result of asteroid impacts or delayed, huge scale volcanism that put significant volumes of carbon dioxide into the atmosphere – prompting warming, fermented seas, and even mass extinctions.
The doubt, obviously, is that we are currently in another of these incredible irritations.
In the course of recent years, carbon outflows from human exercises, for example, through the consuming of petroleum products have been 40 to multiple times more prominent than our planet's geologic carbon emissions.
"It's really revealing that the amount of carbon dioxide we're emitting in a short time period is very close to the magnitude of those pervious catastrophic carbon events," said Dr Celina Suarez from the University of Arkansas
"A lot of those ended in mass extinctions, so there are good reasons why there is discussion now that we might be in a sixth mass extinction."
While this may sound discouraging, there is some cheerful news in the new study.
In attempting to check the measure of carbon transmitted from volcanoes, the DCO researchers have found that eruptions are all the time gone before by floods in gas release.
"Putting very high-resolution sensors on crater rims allowed us to see very short time-scale changes in CO2 flux," clarified Prof Edmonds.
"The flux increased dramatically in the days and weeks before eruptions. We think this holds great promise for forecasting in the future, when used in tandem with things like volcano seismicity, and how the ground is moving."
