8.2 ka的突然冷事件对欧洲和近东的人类人口，定居模式和文化的潜在影响已成为当前讨论和辩论的一个关键主题。我们测试这一事件是否对苏格兰西部的中石器时代人口的影响，位于北大西洋地区的8.2 ka事件的环境影响可能是最严重的案例研究。通过对放射性碳记录进行贝叶斯分析，并使用活动事件的数量作为人口规模的代理，我们发现了与8.2 ka事件同步的中石器时代人口急剧减少的证据。我们认为这反映了低密度人口的人口崩溃，缺乏适应新环境条件快速发生的能力。北大西洋地区8.2 ka事件的这种影响使人们相信，欧洲大陆和近东地区的人口可能会受到类似的影响。
The potential impact of the abrupt 8.2 ka cold event on human demography, settlement patterns and culture in Europe and the Near East has emerged as a key theme in current discussion and debate. We test whether this event had an impact on the Mesolithic population of western Scotland, a case study located within the North Atlantic region where the environmental impact of the 8.2 ka event is likely to have been the most severe. By undertaking a Bayesian analysis of the radiocarbon record and using the number of activity events as a proxy for the size of the human population, we find evidence for a dramatic reduction in the Mesolithic population synchronous with the 8.2 ka event. We interpret this as reflecting the demographic collapse of a low density population that lacked the capability to adapt to the rapid onset of new environmental conditions. This impact of the 8.2 ka event in the North Atlantic region lends credence to the possibility of a similar impact on populations in Continental Europe and the Near East.
