Owing to the nature of their formation, loess-paleosol sequences are valuable terrestrial archives in investigating past variability in the long-term global dust dynamics. As the primary constituent of loess and a major component of global climate forcing, mineral dust serves as a proxy that allows for direct comparison of loess data with chronologically better resolved ice and lacustrine records. Motivated by the recent emergence of high-resolution magnetic and sedimentological data on Lower Danube loess-paleosol profiles, we explore advances and drawbacks in comparing regional paleoenvironmental response to millennial-scale climate variability during last glacial cycle. We show that the Lower Danube loess preserves a convincing record of millennial-scale variability that resembles the Greenland interstadials/stadial variability. In order to explore regional patterns of change, we also focus in comparing loess records with better-established lacustrine and marine records from southeastern Europe. As reliable chronological control is still the major limiting factor in exploring the full paleoclimate potential of loess records, we also discuss regional implications in defining an improved loess chronostratigraphic framework based on several lines of chronological evidence, including tephrochronology.
