Even aside from plants that grow in it, the other organisms in soil can respire and break down compounds to produce CO2, adding to what's in the atmosphere already. There has long been observed a relationship between ambient temperatures and this respiration in soil, such that more heat means more activity and more gases released from the soil, but today's study found that the microbial biomass in a given piece of land can have a big effect on the temperature/respiration relationship.
