Microbial contribution to climate change

Microorganisms are among the most ancient life forms on Earth, yet their influence reaches far beyond their microscopic size. They are powerful drivers of biogeochemical cycles, shaping the flow of carbon, nitrogen, and other essential elements through the environment. In recent decades, the growing urgency of global climate change has renewed scientific attention toward microbes—not only as contributors to greenhouse gas emissions but also as key allies in climate mitigation.
