WebThe early atmosphere probably contained: little or no oxygen a large amount of carbon dioxide water vapour small amounts of other gases, such as ammonia and methane Scientists cannot be sure... WebNatural sources of carbon monoxide in Earth's atmosphere include volcanoes and bushfires. Volcanic gases contain between 0.01 and 2% carbon monoxide. Humans contribute vast quantities of CO to our atmosphere, mostly as a result of automobile emissions. Carbon monoxide is the most abundant, by mass, pollutant gas.
