Carbon Dioxide
No, the amount of carbon dioxide in the atmosphere is 0.04% or 400 ppm (parts per million). This has risen since the Industrial Revolution from 280 ppm, when we began burning fossil fuels (coal, oil and natural gas).
Levels of carbon dioxide in 1750 were approximately 275 parts per million. Today (2011) concentrations are approximately 392 ppm, an increase of more than 40 percent.

Before the Industrial Revolution, the world human population growth rate was about .1 percent (.001) per year for the seven to eight centuries. At the beginning of the Industrial Revolution in the mid 1700s, the world's human population grew by about 57 percent to 700 million, and reached 1 billion by 1800. This was mostly do to great advancements in the field of medicine and health, as well as an improvement to the general standards of living.
