Web2 days ago · For decades, scientists believed that the atmosphere of early Earth was highly reduced, meaning that oxygen was greatly limited. Such oxygen-poor conditions would have resulted in an atmosphere filled with noxious methane, … 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.
