Abstract ± ± ∘ C higher in cropland and grassland soils compared to forest soils. Cumulative degree days (the annual sum of daily mean temperatures 〉 ∘ C) increased significantly by 773 ± ± ± ± 8.6 % in cropland topsoil and subsoil compared to forest soils, but no significant difference in decomposition was found between grassland and forest soils. Increased litter decomposition may be attributed not only to increased temperature but also to management effects, such as irrigation of croplands. The results suggest that deforestation-driven temperature changes exceed the soil temperature increase that has already been observed in Canada due to climate change. Deforestation thus amplifies the climate–carbon feedback by increasing soil warming and organic matter decomposition.
