The relative importance of climate and human activities in shaping fire patterns is often debated and has implications for how we approach fire management today.

"While there is little doubt that climate plays an important top-down role in shaping fire patterns, it is far less clear whether human activities—including active burning—can override those climate influences," said Roos. "Too often, if scientists see strong correlations between fire activity and climate, the role of humans is discounted."
