Southern Hemisphere westerly wind changes during the Last Glacial Maximum: paleo-data synthesis

► We synthesize moisture, ocean front, sea-surface temperature, dust, and productivity data. ► We use the data to address possible changes in westerly winds during the last Ice Age. ► Strengthening, equatorward shifts, or no change in winds are all consistent with data. ► Resolving changes in westerly winds during the Ice Age is elusive based on data alone.
