Scientists believe that the carbon levels in the atmosphere are growing, thus throwing off the stability of the Earth's atmospheric carbon. What are some reasons that more carbon is building up in the atmosphere, while less oxygen is being produced?

There is overwhelming evidence that human activities, especially burning fossil fuels, are leading to increased levels of carbon dioxide and other greenhouse gases in the atmosphere, which in turn amplify the natural greenhouse effect, causing the temperature of the Earth's atmosphere, ocean, and land surface to
