Abstract
This publication mirrors the structure of the Antarctic Climate Evolution (ACE) program (www.ace.scar.org), an international initiative of the Scientific Committee on Antarctic Research (SCAR), affiliated with the International Polar Year 2007–2009, to investigate past changes in Antarctica by linking climate and ice sheet modeling studies with terrestrial and marine geological and geophysical evidence of past changes. The program is designed to determine climate conditions and change in both the recent past (i.e. during the last glacial maximum, when temperatures were cooler than at present) and the more distant past (i.e. in the pre-Quaternary, when global temperature was several degrees higher than it is today). This new cross-disciplinary approach has led to a substantial improvement in the knowledge base on past Antarctic climate and to the understanding of the factors that have guided its evolution. This in turn allowed building hypotheses, examinable through numerical modeling, how the Antarctic climate will respond to present and future global changes.
