Humans continue to burn fossil fuels (coal, oil and natural gas) at a great rate in industry, travel and to generate electricity. This releases extra carbon from millions of years ago.
They also cut down forests all over the world that used to absorb carbon dioxide from the atmosphere.

Receptors that detect carbon dioxide levels in the blood are?
Chemoreceptors detect the levels of carbon dioxide in the blood.
Why do carbon dioxide levels decrease when it's cold outside?
No, carbon dioxide levels in the atmosphere increaseduring autumn and winter. When spring begins in the northern hemisphere (where most of the world's vegetation is) all the growing plants and trees start taking carbon dioxide out of the atmosphere. They continue during their growing spell during spring and summer. As the weather gets colder they stop growing. Then the carbon dioxide builds up in the atmosphere.
What are the levels of atmospheric carbon dioxide just prior to the beginning of the industrial age in the mid-1700s and in 2004?
In the mid-1700s the levels of carbon dioxide in the atmosphere were about 280 ppm (parts per million).In 2004 the levels of carbon dioxide in the atmosphere were about 375 ppm.In 2012 the levels of carbon dioxide in the atmosphere were about 393 ppm.
What is an increase in the atmospheric levels of carbon dioxide is the biggest contributor?
An increase in the atmospheric levels of carbon dioxide is the biggest contributor to global warming.
Why might blood carbon dioxide levels be higher in an individual with pulmonary disease when compared to the carbon dioxide levels of a healthy person?
When you have pulmonary disease, you may fail to give out carbon dioxide. So the percentage of carbon dioxide increase in your blood. That is the indicator of the severity of the pulmonary disease.
What happens to the carbon dioxide produced by your body during the period of apnea?
Carbon dioxide levels increas
What happened to the plasma levels of carbon dioxide during exercise why?

What were the carbon dioxide levels during the ice age?
very low
How does the process of photosynthesis affect carbon dioxide concentrations in the atmosphere during a typical year?
Photosynthesis uses carbon dioxide as a raw material where carbon dioxide is fixed into organic molecules. This process lowers the level of carbon dioxide in the atmosphere. The seasonal fluctuation of carbon dioxide levels during a year may be caused by increased photosynthesis during spring and summer.
What happens to the levels of carbon dioxide and water during aerobic exercise compared to their levels when the performer is at rest?
eutrophication
Receptors that detect carbon dioxide levels in the blood are?

Why you breathe out carbon dioxide?
We breathe out carbon-dioxide because high levels of carbon-dioxide in the body can be toxic By Akhilesh Sharma
