Summary The reconstruction of the climatic and environmental history along the East Antarctic coastal regions is mainly based on investigations of geomorphological features and of biological proxies in lacustrine and marine sediment sequences. Although some consistencies in the onset and duration of warm and cold periods after deglaciation apparently exist, some records indicate significant differences from other records close by. These differences may partly be explained by dating uncertainties, overprinting of local factors, or possibly even misinterpretations of the proxies used. A comparison with the climate histories deduced from ice core records reveals, however, that the differences have at least partly to be caused by local effects and small-scale variations, which still need to be better understood and demonstrate the need of further research.
