Calibration of the microcharcoal proxy preserved in marine sediments and reconstruction of paleo-fires in the Western Mediterranean region during the Holocene

1 - IntroductionFires significantly affect future ecosystems, society, and climate systems, requiring projections based on observational data (Rogers et al., 2020). To assess model reliability, comparisons with contemporary data and historical climate conditions are essential (Hantson et al., 2016). Analyzing microcharcoal in marine and lake sediments aids in understanding burnt biomass evolution, though it does not specify fire regimes. This PhD thesis seeks to enhance knowledge through two...
