Microbial interactions between climate warming and antimicrobial resistance threaten soil carbon storage and global health
Abstract. Anthropogenic activities are impacting the environment in ways that may intersect and have compounding effects. In soil, the spread of antibiotic

Could rising antimicrobial activity in warmer soils make microbes less efficient at using carbon & push more CO₂ into the atmosphere?
