Climate change and microbial life: A critical analysis of their reciprocal relationship

Abstract

Microorganisms are vital yet often overlooked agents in global ecological and climatic systems. They regulate critical processes such as nutrient cycling, organic matter decomposition, and greenhouse gas fluxes. Climate change-marked by rising temperatures, altered precipitation, and extreme events-profoundly affects microbial communities, influencing their structure, function, and interactions with ecosystems. In turn, microbial activity both contributes to and mitigates climate change, through processes like methane and nitrous oxide emissions or carbon sequestration. Technological advances, including metagenomics and stable isotope probing, have revolutionized microbial ecology, offering insights into microbial roles in climate dynamics. Integrating microbial data into climate models enhances predictive accuracy and informs mitigation strategies in agriculture, carbon management, and ecosystem restoration. Recognizing microbes as central players in climate systems is crucial for developing nature-based, scalable, and sustainable climate solutions. Harnessing microbial potential offers a transformative path toward planetary resilience in the face of accelerating environmental change.
