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.

The carbon cycle stores approximately 3 trillion metric tons of carbon in various reservoirs, including the atmosphere, oceans, soil, and living organisms. The atmosphere contains about 3,000 billion tons of carbon dioxide, while oceans hold around 38,000 billion tons. Terrestrial ecosystems, including forests and soils, store significant amounts as well, making the carbon cycle crucial for regulating Earth's climate and supporting life. Overall, the dynamic exchanges within this cycle play a vital role in maintaining the planet's ecological balance.
Forests play an important role in the carbon cycle, moving carbon dioxide out of the atmosphere through photosynthesis, storing the carbon and releasing the oxygen. Deforestation, which means destroying forests, not just trees, removes all the trees which have been acting as a great carbon sink, or store.This means that carbon dioxide, a powerful greenhouse gas, and one that is largely responsible for man-made global warming is not removed from the atmosphere as much as it was before.The US Supreme Court has classed carbon dioxide in the atmosphere as pollution.
False.
Mars, Venus's atmosphere is thicker than Earth's. Much thicker.

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.
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.
Approximately 37.1 billion metric tons of CO2 are released into the atmosphere each year from fossil fuel combustion, accounting for the majority of anthropogenic carbon emissions.
Approximately 36 billion metric tons of carbon dioxide are released into the atmosphere each year from burning fossil fuels. This significant amount of carbon dioxide is a leading contributor to the greenhouse effect and global warming.
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.
According to Wikipedia's List of countries by carbon dioxide emissions the US emits 5,838,381,000 metric tonnes annually, which is 19.91% of the global total (Figures from 2007).
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!
Approximately 36 billion metric tons of carbon dioxide are released each year from burning fossil fuels. This carbon dioxide is released into the atmosphere, where it contributes to the greenhouse effect and climate change.

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.
