来自北爱尔兰三个凸起沼泽的多代古水文记录表明，向更湿/更冷的气候条件的重大转变比2800 cal. BP太阳活动的快速减少晚了约100年。在每个剖面中，这一事件被两个摆动匹配的放射性碳年代隐层所包围，从而实现了高度的年代精度。这些重复的数据证实了先前基于爱尔兰泥炭腐殖化剖面的发现，并可能表明海洋和大陆地区之间气候对太阳活动响应的空间复杂性。
Multiproxy palaeohydrological records from three raised bogs in Northern Ireland indicate that a major shift to wetter/cooler climatic conditions postdated the rapid decrease in solar activity at 2800 cal. BP by ~100 years. This event is bracketed by two wiggle-match radiocarbon-dated cryptotephra layers in each profile, enabling a high degree of chronological precision. These replicated data corroborate previous findings based on Irish peat humification profiles, and may indicate spatial complexity in the climatic response to solar activity between oceanic and continental areas.
