Nearly all of Earth’s plant life responds favorably to increases in the air’s CO2 content by exhibiting enhanced rates of photosynthesis and biomass production. Consequently, these phenomena tend to increase soil carbon contents by increasing root exudation of organic compounds and the amount of plant litter returned to the soil. Thus, one might expect CO2-mediated increases in soil carbon content to impact soil bacterial communities; and this summary explores the findings of several scientists who have studied the effects of elevated CO2 on bacteria.
