Antarctica before ice sheets: polar climate history of past greenhouse worlds

该项目旨在记录南极在过去5000万年的“温室”时期的气候行为，为大规模冰盖开发做准备。将讨论有关南极气候在二氧化碳水平高于目前水平的时间间隔中的长期和短期变化的基本问题。在假设的温暖“温室”时期，南极洲是否存在降温和大量积冰的阶段？如果是这样的话，小冰盖或沿海冰川是长期存在的，还是短暂的？

This project aims to document Antarctic climate behaviour during 'greenhouse' periods of the past 50 million years in the lead-up to large-scale ice-sheet development. Fundamental questions will be addressed regarding both long- and short-term Antarctic climate variability in time intervals with higher-than-present CO2 levels. Were there phases of cooling and extensive ice accumulation in Antarctica during hypothesized warm 'greenhouse' periods? If so, did small ice sheets or coastal glaciers persist for long periods of time or were they ephemeral?
