The total mass of CO2 is about 3 trillion tonnes (3 teratonnes). (That's a 3 with 12 zeros, 3,000,000,000,000 tonnes.)
C12 + 2O16 means 12 parts in 32, by weight, are carbon. 3/8ths. So, 1-1/8 teratonnes.
That is about 2.5 quadrillion pounds, or 1.125 quadrillion kg.
Carbon in the atmosphere is mostly found in the form of carbon dioxide (CO2), which makes up about 0.04% of the atmosphere. Carbon can also exist in the form of methane (CH4) and other greenhouse gases in smaller concentrations.
Carbon dioxide does not leave the atmosphere into space, but rather back to the earth and the oceans. Much of it is taken up by plants through photosynthesis, while much of the remainder is taken up by oceans. Oceans, however, also outgas a considerable amount, so it is not just a one-way transport.
There are two such planets, Mars and Venus. Venus has a much thicker atmosphere than Mars, but both atmospheres are about 95% carbon dioxide.
Venus and Mars are two planets in our solar system that have significant amounts of carbon dioxide in their atmospheres. Venus has a thick atmosphere composed mainly of carbon dioxide, while Mars has a much thinner atmosphere with trace amounts of carbon dioxide.
carbon dioxide
About 2,500 gigatons of carbon are estimated to be stored in the Earth's soil. This amount is roughly three times more than the carbon currently in the atmosphere. Soil carbon plays a crucial role in regulating the global carbon cycle and climate.
Most of carbon in the atmosphere is in the form of CO2. At nearly 400 ppm, that pencils out to 3 trillion tonnes (metric tons). To single out how much of that is carbon we need to multiply by 12 (molecular weight of carbon) and divide by 32 (molecular weight of O2). That works out to 1.1 trillion tonnes. There is additional carbon in the atmosphere in the form of methane (CH4), carbon monoxide (CO), chlorofluorocarbons (CFC), and a few other carbon compounds. If you count pollen, wind born leaves, birds, and other things occasionally swept aloft, the atmosphere temporarily suspends much more carbon yet.
Respiration (breathing) has no effect on the amount of carbon dioxide in the atmosphere. Breathing is part of the carbon cycle. We take in carbon in our food and drink and we release it again when we breathe. If we eat too much, the extra carbon is stored in our bodies, making us fatter, in much the same way as a tree stores carbon in its wood as it grows.So breathing does not increase or decrease the amount of carbon dioxide in the atmosphere.
It is a problem because the carbon has been stored for 300 million years. Adding it to the atmosphere now is too much for the carbon cycle to manage, so levels build up causing global warming.
it should still be carbon, but too much carbon is bad for the atmosphere. Google: "Carbon in atmoshpere" and see why it's bad
Soil stores a significant amount of carbon, with estimates suggesting it holds two to three times as much carbon as the atmosphere. This stored carbon is mainly in the form of organic matter derived from plant materials and microorganisms. Proper soil management practices, such as reducing tillage and adding organic amendments, can help enhance carbon storage in soils.
Carbon in the atmosphere is mostly found in the form of carbon dioxide (CO2), which makes up about 0.04% of the atmosphere. Carbon can also exist in the form of methane (CH4) and other greenhouse gases in smaller concentrations.
In the short term, yes. As the trees grow, they sequester carbon from the carbon dioxide in the atmosphere by turning it into wood. However, when the tree dies and decays or burns, much of that carbon returns to the atmosphere as carbon dioxide.
The Amazon Basin has had much of its forests destroyed. These trees used to be a carbon sink, that is, they removed and stored carbon dioxide from the atmosphere. Their removal means that global warming is happening more quickly!
95.32% of the Martian atmosphere is Carbon Dioxcide.(aka CO2)
carbon exist in earth crust as 0.02% and in atmosphere 0.03%
Photosynthesis is the main process in the carbon cycle that decreases the amount of carbon dioxide in the atmosphere. During photosynthesis, plants take in carbon dioxide from the air and convert it into carbohydrates and oxygen. This helps to store carbon and reduce the overall concentration of carbon dioxide in the atmosphere.
