Burning carbon requires oxygen (O2), and when we burn an atom of carbon, the required oxygen becomes part of the CO2 molecule. So if the CO2 increase is caused by burning carbon (fossil fuels), we would expect atmospheric O2 levels to decrease at the same rate. And that's indeed what we observe (Figure 1).
Other man-made causes of the increase in the greenhouse effect is the emission of greenhouse gases by electrical appliances. These gases, chlorofluorocarbons (CFCs), are used on a large scale in the electronic industry. Some processes of the cement manufacturing industries also act as a cause towards the greenhouse effect. Population growth is an indirect contributor and one of the major causes of the greenhouse effect. With the increase in population, the needs and wants of people increase which consequently increases deforestation, manufacturing, and industry processes.
