How much of the total global carbon is present in the atmosphere?

The atmosphere contains about 1% of the total global carbon. Most of this carbon is present in the form of carbon dioxide (CO₂), which is a greenhouse gas that contributes to global warming. CO₂ is released into the atmosphere through natural processes like respiration and volcanic activity, as well as human activities such as the burning of fossil fuels.
The majority of carbon is found in rocks, oceans, soil, and living organisms. Carbon in rocks is present in the form of minerals such as limestone and coal. Oceans are major carbon sinks, as they absorb and store large amounts of carbon from the atmosphere.
