Antarctica

Kreutz et al. (1997) compared results from studies of West Antarctic ice cores with the Greenland Ice Sheet Project Two GISP2; they suggested a synchronous global cooling. An ocean sediment core from the eastern Bransfield Basin in the Antarctic Peninsula shows centennial events, which the authors link to the Little Ice Age and to the Medieval Warm Period. The authors note that "other unexplained climatic events comparable in duration and amplitude to the LIA and MWP events also appear."

The Siple Dome (SD) had a climate event with an onset time that is coincident with that of the Little Ice Age in the North Atlantic, based on a correlation with the GISP2 record. The Little Ice Age is the most dramatic climate event in the SD Holocene glaciochemical record. The Siple Dome ice core also contained its highest rate of melt layers (up to 8%) between 1550 and 1700, most likely because of warm summers. Law Dome ice cores show lower levels of CO mixing ratios from 1550 to 1800, which Etheridge and Steele believe to be "probably as a result of colder global climate."

Sediment cores in Bransfield Basin, Antarctic Peninsula, have neoglacial indicators by diatom and sea-ice taxa variations during the Little Ice Age. Stable isotope records from the Mount Erebus Saddle ice core site suggests that the Ross Sea region experienced average temperatures 1.6 ± 1.4 °C cooler during the Little Ice Age than the last 150 years.
