Reconstructing the spatial and temporal response of mountain glaciers to rapid climate change in the past provides access to the effects of current climate change. Yet, the spatial and temporal variability of past glacier fluctuations is not fully understood. In this study, we focus on the timing of glacier fluctuations in the European Alps during the Younger Dryas/Early Holocene (YD/EH) transition. In an effort to elucidate whether glacier fluctuations were synchronous during this period, we present a new chronology of the Alpine Talèfre glacier, based on 14 new ¹⁰Be ages of moraines and roches moutonnées. The retreat of Talèfre glacier was initiated during the mid-YD (~12.4 ka), then it experienced a gradual retreat punctuated by at least three oscillations until ∼11 ka before shrinking substantially within its Little Ice Age limits (13th−19th centuries). Comparison of our findings with published glacier chronologies in the Alpine region highlights broadly synchronous behaviour of glaciers across the Alps between 12 and 10 ka. The coeval glacier fluctuations at a regional scale suggest that common regional climate conditions had a major impact on Alpine glacier variations during the YD/EH transition. The similarity of glacier behaviour and independent temperature records in both the Alpine region and the northern high latitudes suggests a teleconnection between these regions, but differences in the amplitude of the mean annual temperature signals relative to summer temperature indicate pronounced changes in seasonality between the YD and the EH.

在新仙女木和全新世早期之间的欧洲阿尔卑斯山千禧年规模的冰川消退——来自新宇宙成因核素年表的证据

重建山地冰川对过去快速气候变化的时空响应，可以了解当前气候变化的影响。然而，过去冰川波动的空间和时间变化尚不完全清楚。在这项研究中，我们关注年轻仙女/早期全新世 (YD/EH) 过渡期间欧洲阿尔卑斯山冰川波动的时间。为了阐明这一时期的冰川波动是否同步，我们根据 14 个新的¹⁰是冰碛和 roches moutonnées 的年龄。Talèfre 冰川的退缩始于 YD 中期（~12.4 ka），然后它经历了一个逐渐退缩，中间至少有 3 次振荡，直到~11 ka，然后在其小冰河时代范围内（13-19 世纪）大幅收缩。将我们的发现与阿尔卑斯地区已发表的冰川年表进行比较，突出了 12 至 10 ka 之间跨越阿尔卑斯山的冰川的广泛同步行为。区域尺度的同期冰川波动表明，共同的区域气候条件对YD / EH过渡期间的高山冰川变化产生了重大影响。阿尔卑斯地区和北部高纬度地区冰川行为和独立温度记录的相似性表明这些地区之间存在遥相关，
