英文摘要	The sensitivity of soil microbial respiration to warming (Q10) remains a major source of uncertainty surrounding the projections of soil carbon emissions to the atmosphere as the factors driving Q10 patterns across ecosystems have been assessed in isolation from each other. Here we report the results of a warming experiment using soils from 332 sites across all continents and major biomes to simultaneously evaluate the main drivers of global Q10 patterns. Compared with biochemical recalcitrance, mineral protection, substrate quantity and environmental factors, the soil microbiome (that is, microbial biomass and bacterial taxa) explained the largest portion of variation in Q10 values. Our work provides solid evidence that soil microbiomes largely govern the responses of soil heterotrophic respiration to warming and thus need to be explicitly accounted for when assessing land carbon-climate feedbacks. The authors use experimental data from 332 sites across all major global biomes to evaluate the drivers of soil microbial respiration response to warming. They demonstrate a key role of the soil microbiome, highlighting the need to account for this in assessments of soil respiration under change.
