Description: 
The best record of Quaternary climatic change in Antarctica is provided by indications of multiple glaciations in the now glacier-free area of Victoria Land. Although no quantitative data on change at snow line, temperature, and precipitation are yet available, multiple glaciation provides the first qualitative record of climatic change on the continent. The climate was colder and/or wetter than now during at least four episodes when glaciers were more extensive. The interglacials or inerstadiales may have had a climate only slightly warmer than now. Glacial meltwaters created glacial lakes which have since disappeared, partly by evaporation. The glaciers have been retreating for at least the last 6,000 yr as a result of warming of the climate and/or perhaps of decrease in precipitation. From at least two Antarctic localities, there is a record of a warming trend over the last 50 yr, ranging from 0.057 degrees C/year to 0.077 degrees C/year.
