Definitions for "CARBON DIOXIDE"
a greenhouse gas whose atmospheric concentrations have been increasing from pre-industrial (1750-1800) levels of 280 parts per million (ppm) to present day levels of 356-360 ppm, depending on location.

A main source of CO2 increase in the atmosphere has been the burning of fossil fuels.
