Responses of soil organic carbon to climate extremes under warming across global biomes

Subjects

Abstract

The impact of more extreme climate conditions under global warming on soil organic carbon (SOC) dynamics remains unquantified. Here we estimate the response of SOC to climate extreme shifts under 1.5 °C warming by combining a space-for-time substitution approach and global SOC measurements (0–30 cm soil). Most extremes (22 out of 33 assessed extreme types) exacerbate SOC loss under warming globally, but their effects vary among ecosystems. Only decreasing duration of cold spells exerts consistent positive effects, and increasing extreme wet days exerts negative effects in all ecosystems. Temperate grasslands and croplands negatively respond to most extremes, while positive responses are dominant in temperate and boreal forests and deserts. In tundra, 21 extremes show neutral effects, but 11 extremes show negative effects with stronger magnitude than in other ecosystems. Our results reveal distinct, biome-specific effects of climate extremes on SOC dynamics, promoting more reliable SOC projection under climate change.

Extended Data Fig. 3 The comparison of soil organic carbon changes induced by changes in extreme dry magnitude using our approach with file drought experimental results.

Comparison of soil organic carbon changes induced by changes in extreme dry magnitude (EDM). Deng et al. (2021) synthesized the data from field experiments. Biomes are grouped into tundra, shrublands, grasslands, and forests. Dots with bars show the mean effect sizes with 95% confidence intervals, and numbers besides them are sample sizes used to calculate the mean effect size. The actual drought levels (that is, the reduction of precipitation) in field drought experiments were normalized to annual mean precipitation. The change level in our estimation which is close most to the experimental change level was targeted to conduct the comparison.
