Fig. 2: Relationships between the predictors and causes of fire and burned area.
From: Extratropical forests increasingly at risk due to lightning fires
a–d, Lightning fires (a,b) and the burned area attributed to lightning (c,d) tend to be dominant in areas with low human impact. Furthermore, lightning fires (a) and the burned area from lightning (c) also tend to have a high seasonal correlation between lightning and burned area. Finally, human-dominated fire regimes are found in regions with a low seasonal correlation between fire weather and burned area (b,d). Data points represent 0.5° geospatial grid cells obtained from reference data from seven world regions (Extended Data Fig. 1).
