The domain-wide βΔΤ value was 0.44 ± 0.01 K (log10[km2])−1 (Fig. 1f), showing that, in summer, for every doubling in fire size, postfire land surface becomes warmer by 0.13 ± 0.01 K, or 22% of the regional average warming (0.60 K; Fig. 1f)....
The size-enhanced summer surface warming was driven by systematic changes in land surface energy processes following fire, almost all of which were amplified by fire size (Fig.2a,band Extended Data Fig.1). As a result of the removal of the forest canopy and darkening of the ground surface22...
