Soil moisture-atmosphere coupling accelerates global warming

L. Qiao, Z. Zuo, et al.

Discover how soil moisture-atmosphere coupling is set to amplify global warming by 2100, driving extreme temperatures across the globe—especially in North America and Europe. This groundbreaking research, conducted by Liang Qiao, Zhiyan Zuo, Renhe Zhang, Shilong Piao, Dong Xiao, and Kaiwen Zhang, highlights the urgent implications of the ‘warmer climate – drier soil’ feedback mechanism.

Abstract

Soil moisture-atmosphere coupling (SA) amplifies greenhouse gas-driven global warming. The Scenario Model Intercomparison Project projects an acceleration in SA-driven warming due to the ‘warmer climate – drier soil’ feedback, exceeding 0.5°C over extratropical landmasses by 2100 under high emissions. This increases the likelihood of extreme high temperatures globally, particularly in North America and Europe. SA demonstrates high sensitivity to climate change, exceeding natural climate variability and exhibiting a nonlinear warming effect.
