Emergent Climatic Controls on Soil Carbon Turnover and Its Variability in Warm Climates

Geophysical Research Letters, 2023
Climate plays a critical role in altering soil carbon (C) turnover and long‐term soil C storage by regulating water availability and temperature, and in turn biological activity. However, a systematic analysis of how key climatic factors shape the global
