Carbon and hydrogen isotope compositions of leaf wax n-alkanes, climate variables and age-depth models used to constrain hydrological regimes along Chile during the last 20,000 years. Charlotte Läuchli et al. https://doi.org/10.5880/fidgeo.2025.050

Short summary

Large-scale atmospheric pathways connecting climate across latitudes are poorly documented in the past. Using a high-resolution spatial and temporal reconstruction of the evolution of the Southern Hemisphere Westerlies since the Last Glacial Maximum and comparing it with the evolution of the Intertropical Convergence Zone, we identified the dominant atmospheric pathways that shaped past South American climate.
