摘要：Terrestrial and marine paleoclimate records are very sparse in the southern hemisphere, particularly at high latitudes. However, this is where ice cores come into their own. Antarctic ice cores provide a firm and well-resolved anchor for our understanding of how climate has evolved over 800 kyr, and provide climate information for assessing how the Antarctic Ice Sheet may have varied over the same period. They are also the best archive for determining the history of greenhouse gas concentrations and offer unique data on other important forcings, such as volcanic aerosol and solar.
