No solid evidence of soil carbon loss under warming in tropical forests along a 3000 m elevation gradient

Abstract

1Soil organic carbon (SOC) decomposition is inherently sensitive to temperature. As such, a 1 2 big concerning is the potential SOC loss under climatic warming, but field empirical 1 3 evidences are lacking, particularly in tropical forest soils in which ~10% of global SOC is 1 4 stored. Recently Nottingham et al. (2019) assessed the data collected from a novel 1 5 experiment translocating soils across a 3000 m tropical forest elevation gradient to mimic 1 6temperature changes in situ, and concluded that warming caused considerable SOC loss.
