Fig. 2: Charcoal accumulation rate throughout the Holocene indicates a trend from higher (Early Holocene) to lower (Late Holocene) levels of biomass burning.

A Composite curve of Yakutian charcoal records, standardized, using a base period from −70 to 11,000 years BP. Shaded area represents the 95% confidence interval. Star symbols indicate peaks of individual records that extend beyond the plotting area. B Temporal coverage of individual records included in the composite curve. Black dots indicate age control points for each record, including radiocarbon ages, surface ages as year of core extraction, and lead-210, cesium-137 ages (Lake Khamra only). Star symbol marks charcoal record extending beyond the analyzed time frame (Lake Sugun only).
