When the individual has a high level of carbon dioxide in the blood, the condition is known as hypercapnia. One of the most common causes of high levels of carbon dioxide in the body is hypoventilation. This means that the person is not breathing fast enough to support the functions of the body.
The burning of fossil fuels releases the carbon dioxide removed from the atmosphere hundreds of millions of years ago. Other carbon dioxide sources include volcanoes and bush fires. A: The single largest factor for increasing atmospheric CO2 is the burning of fossil fuel. Human beings release 30 billion tons of CO2 into the atmosphere each year from fossil sources. Over the decades this has lead to an increase from 280 parts per million to now over 390 ppm of CO2.
