TL;DR: The Global Charcoal Database version 3 (GCDv3) as discussed by the authors contains 736 charcoal records (57 more than in version 2) and provides new 1000-year and 22'000-year trends and gridded biomass burning reconstructions.

TL;DR: The results suggest that for the last 18,000 y, fires have been predominantly limited by fuel discontinuity rather than by suitable climate conditions, suggesting that climate–vegetation–fire linkages in northern Patagonia evolved with minimal or very localized human influences before European settlement.

TL;DR: Pollen and charcoal data from eleven sites located along the eastern flanks of the Patagonian Andes (41-43°S) were examined to reconstruct the Lateglacial and Holocene vegetation and fire history of steppe/forest ecotone and separate the relative influence of climatic versus non-climatic factors in shaping the patterns of ecological change as mentioned in this paper.

TL;DR: The use of sedimentary charcoal as a fire proxy and the methods used in charcoal-based fire history reconstructions are reviewed and opportunities for coupling of paleoecological and ecological modeling approaches are evaluated to better understand the causes and consequences of past, present, and future fire activity.

TL;DR: It is concluded that recent extremes should not be surprising, and that the contiguous United States may be on the verge of even larger wildfire extremes.
