Microbes in soil play a key role in the global carbon cycle by metabolizing organic matter and releasing over 60 Pg of carbon per year. Since the composition and activities of microbes are strongly influenced by changes in environmental conditions such as temperature, water availability, oxygen penetration, and carbon supply, global climate change may exert climate-microbial feedbacks to accelerate or alleviate GHG emission. In the present study, we review effects of temperature rise, precipitation change, and elevated CO2 on soil microbial composition and process rates. Furthermore, we suggest several topics that should be addressed to better understand microbial feedbacks to the future climate read more ...
