Volcanos release sulfur dioxide, carbon dioxide, and ash to the atmosphere at the same time
Respiration :)
Burning fossil fuels (coal, oil and natural gas) and deforestation increase the amount of carbon dioxide in the atmosphere. Respiration and other aspects of the carbon cycle do not increase the amount as a similar volume is being removed at the same time.
In the past 50 to 100 years, man has burned about one halve of all the oil which formed through the ages, plus large amounts of coal, lumber, and natural gas. This is the source of the carbon dioxide. It would be worse except the oceans absorbed some of the carbon dioxide increase.
Any fossil fuels, hydrocarbons like coal, oil and natural gas, release carbon dioxide and water when burned.
The calvin cycle removes carbon dioxide from the air and uses it to form carbohydrates in plants. The burning of fossil fuels releases trapped carbon dioxide from the fuel and releases it back into the atmosphere.
Nature produces the vast bulk of carbon dioxide in the atmosphere. Rotting trees, and dead matter produce over 90% of the current levels of carbon dioxide. Man produces between 3 and 6 percent of all CO2 annually.

the atmosphere is the main source of CO2 in the ocean
