Human influence, climate, and fire activity

Proceedings of the National Academy of Sciences

Modeling of historic annual fire activity for 37 regions across the continental United States indicates that the relative importance of seasonal temperature, seasonal precipitation, and overall climate in explaining fire activity varied substantially with geography, and that human presence reduced the influence of climate on fire in some regions, according to a study.
