Rising global temperatures across the 20th and 21st centuries has caused the dramatic loss of ice volume. Ocean-Cryosphere interactions are considered to have been direct forcing factors for the trigger of Abrupt Climatic Events (ACEs) over geological time. Such events, therefore, offer suitable analogues for understanding the possible consequences of transgressing social and ecological tipping points under current and projected climatic warming. ACEs over the Holocene (11,700-present) have been proposed as having transformative impacts on human culture. The 8.2ka event, as the largest magnitude period of abrupt climate change during the Holocene, may therefore be considered as a key time to investigate the Mesolithic (10000-4000 BC) response to climatic stress. Many studies, however, have critical issues with either the chronology, the resolution of palaeocological records, or the statistical methods employed, limiting the efficacy of their conclusions. A more robust analysis will be achieved by producing high-resolution palaeoclimatic and palaeoecological records detailing seasonal climatic change, which detail how climate variations impacted key controls on human activity, such as resource availability. Quality assurance of the radiocarbon dataset will also be performed. Evidence for a relationship between societal change and climate forcing will then be tested using Radiocarbon-date Event Count Event modelling.

在20世纪和21世纪，全球温度的上升导致了冰量的巨大损失。海洋 - 晶相互作用被认为是在地质时期突然气候事件（ACE）触发的直接迫使因素。因此，此类事件提供了适当的类似物，以理解在当前和预计的气候变暖下违反社会和生态临界点的可能后果。全新世上的ACE（11,700个存在）被认为是对人类文化的变革性影响。因此，8.2KA事件是全新世期间突然的气候变化的最大幅度时期，因此可以被视为研究中石器时代（公元前10000 - 4000年）对气候应力的反应的关键时机。然而，许多研究在年代学，清真学记录的解决或所采用的统计方法方面存在关键问题，从而限制了其结论的疗效。通过产生高分辨率古气候和古生态记录，详细介绍季节性气候变化，可以实现更强大的分析，这些记录详细介绍了气候变化如何影响对人类活动的关键控制，例如资源可用性。还将执行放射性碳数据集的质量保证。然后，将使用放射性碳日期事件事件建模来测试社会变化与气候强迫之间关系的证据。
