格陵兰冰芯、现代和古代木材样本以及海洋有孔虫中的同位素记录提供了Allerod-Bolling-Younger Dryas和后Younger Dryas时期的气候记录，这与格陵兰冰芯中H-2/H-1比率的通常气候解释不一致。例如，新仙女木事件不仅仅是北大西洋事件，因为在阿拉斯加北坡生长的木材样本的H-2/H-1记录中也发现了它的证据。新仙女木不一定是冰盖冷却的时期。此外，在北方大陆的温带地区，这可能是一个变暖时期。要更好地了解这些时期的气候情景，可以从这些时期生长的植物遗骸中的其他同位素数据中确定，这些植物遗骸覆盖了大陆上更广泛的气候范围。
The combined isotopic records in the Greenland ice cores, in modern and ancient wood samples, and in marine foraminifera provide a climatic record for the Allerod-Bolling-Younger Dryas and post-Younger Dryas Periods that is not compatible with the usual climatic interpretation of the H-2/H-1 ratios in the Greenland ice cores. For example, the Younger Dryas was not solely a North Atlantic event because evidence for it is also found in the H-2/H-1 record in wood samples which grew on the north slope of Alaska. The Younger Dryas was not necessarily a time of cooling over the ice caps. Moreover, it might have been a warming period in the temperate zones of the northern hemisphere continents. A better understanding of the climatic scenarios during these periods of time could be ascertained from additional isotopic data in plant remains which grew during these intervals and which cover a wider climatic range on the continents.
