Ice and lake core proxy records provide quantifiable data on past fire regimes across all possible spatial and temporal scales. As both levoglucosan and climate parameters are measured from the same depth and time within the ice or sediment matrix, the multi-proxy nature of ice and lake cores presents the perfect material to investigate the links between fires and climate change. We aim to integrate proxy records from seven continents to provide an interdisciplinary synthesis of the interactions between past fires, human activity, and climate change.

The qualitative figure (Figure 2) demonstrates global fire activity in relation to atmospheric carbon dioxide (ppm), the appearance and dispersal of humans, the presence of major vegetation regimes, and natural climate cycles.

Ice and lake core proxy records provide quantifiable data on past fire regimes across all possible spatial and temporal scales. One of the goals of the program is to integrate modern observations of fire and charcoal records with proxy information from seven continents to provide a ground-breaking synthesis of the interactions between past fires, human activity, and climate change.
