用花粉数据解释欧洲大陆冰后期的气候历史已被证明是困难的，部分原因是人类对景观的改造。将气候与人为引起的植被变化分开需要一种确定整个地区变化时间的战略。在过去的12,000年里，我们使用混合模型方法对两个数据集进行了量化，这两个数据集是：来自花粉图的放射性碳日期和来自选定参考地点的区域边界。植被的主要转变，如花粉图所示，似乎在整个大陆同步进行。这些转变也与北美花粉图中确定的转变以及北大西洋海洋记录和格陵兰冰芯中记录的主要环境变化同步。这种同步性表明，在欧洲的主要植被在全新世和晚冰期的转变主要是由大规模的大气环流变化。这些气候变化可能导致了全新世欧洲社会的一些文化，政治和移民变化。
Interpreting the postglacial climate history of the European continent using pollen data has proven difficult due in part to human modification of the landscape. Separating climate from human-caused changes in the vegetation requires a strategy for determining times of change across the entire region. We quantified transitions in the vegetation across Europe during the past 12,000 years using a mixture model approach on two datasets: radiocarbon dates from pollen diagrams and zone boundaries from selected reference sites. Major transitions in the vegetation, as recorded in pollen diagrams, appear synchronous across the continent. These transitions were also synchronous with those identified in North America pollen diagrams and major environmental changes recorded in North Atlantic marine records and Greenland ice cores. This synchronicity suggests that the major vegetation transitions in Europe during the Holocene and late glacial were primarily caused by large-scale atmospheric circulation change. These climate changes may have caused some of the cultural, political and migration changes in European societies during the Holocene.
