Dust and d180 data from South Pole Station indicate that the opposite conditions (e .g. cooler and more dusty) were prevalent there during the LIA. Meteorological data from 1945-85 show that the LIA temperature opposition between Amundsen-Scott and Siple, inferred from d180, is consistent with the present spatial distribution of surface temperature. There is some observational evidence suggesting that under present conditions stronger zonal westerlies produce a temperature pattern similar to that of the LIA. These regional differences demonstrate that a suite of spatially distributed, high resolution ice-core records will be necessary to characterize the LIA in Antarctica.
