Millions of microbes living in the soil could influence how soils respond to temperature changes. They also influence the amount of carbon dioxide soils give off or respire. Yet scientists rarely consider these microbes when modeling temperature effects around the world. An international team of scientists analyzed the results of more than two dozen warming experiments to quantify how much these microbes influence soil respiration under various temperatures and in what ways.
Increased temperatures often lead to soils giving off more organic carbon. More carbon dioxide in the air can in turn increase air temperature. By understanding the influence of microbes living in the soil, scientists can better calculate this carbon dioxide-temperature feedback cycle and predict temperature changes more accurately.
