The rise in atmospheric carbon dioxide (CO2) concentration is a primary catalyst for global warming, and an estimated one fifth of the atmospheric CO2 originates from soil sources. This is partially attributed to the activity of microorganisms, including bacteria, fungi, and other microorganisms that decompose organic matter in the soil utilizing oxygen, such as deceased plant materials. During this process, CO2 is released into the atmosphere. Scientists refer to it as heterotrophic soil respiration.
Based on a recent study published in the scientific journal Nature Communications, a team of researchers from ETH Zurich, the Swiss Federal Institute for Forest, Snow and Landscape Research WSL, the Swiss Federal Institute of Aquatic Science and Technology Eawag, and the University of Lausanne has reached a significant conclusion. Their study indicates that emissions of CO2 by soil microbes into the Earth's atmosphere are not only expected to increase but also accelerate on a global scale by the end of this century.
