Land-use feedback under global warming - a transition from radiative to hydrological feedback regime
Listed in National Center for Atmospheric Research
This study examines the effects of land-use (LU) change on regional climate, comparing historical and future scenarios using seven climate models from phase 6 of Coupled Model Intercomparison Project - Land Use Model Intercomparison Project experiments.
Description
LU changes are evaluated relative to land-use conditions during the preindustrial climate. Using the Community Earth System Model, version 2 - Large Ensemble (CESM2-LE) experiment, we distinguish LU impacts from natural climate variability.
We assess LU impact locally by comparing the impacts of climate change in neighboring areas with and without LU changes. Further, we conduct CESM2 experiments with and without LU changes to investigate LU-related climate processes. A multimodel analysis reveals a shift in LU-induced climate impacts, from cooling in the past to warming in the future climate across midlatitude regions.

For instance, in North America, LU ' s effect on air temperature changes from-0.24 degrees +/- 0.18 degrees C historically to 0.62 degrees +/- 0.27 degrees C in the future during the boreal summer. The CESM2-LE shows a decrease in LU-driven cooling from-0.92 degrees +/- 0.09 degrees C in the past to-0.09 degrees +/- 0.09 degrees C in future boreal summers in North America. A hydroclimatic perspective linking LU and climate feedback indicates LU changes causing soil moisture drying in the midlatitude regions.
This contrasts with hydrology-only views showing wetter soil conditions due to LU changes. Furthermore, global warming causes widespread drying of soil moisture across various regions. Midlatitude regions shift from a historically wet regime to a water-limited transitional regime in the future climate.
This results in reduced evapotranspiration, weakening LU-driven cooling in future climate projections. A strong linear relationship exists between soil moisture and evaporative fraction in midlatitudes.
