摘要

As Earth's climate warms, wildfire frequency and the amount of bio-mass burned are predicted to increase. But few fire prediction models have assessed how climate change may affect fire size. To address this question, Adam Ali et al. (pp. 20966-20970) used sedimentary charcoal records from nine lakes located in the eastern North American boreal forest to reconstruct the region's fire history over the last 7,000 years. The authors deduced the amount of forest cover lost to past fires, as well as past fire frequency, from variations in the rate of charcoal accumulation, and used these metrics to estimate fire size.
