为了回答“最近的变暖在西伯利亚北部没有类似的情况吗？”分析了落叶松（Larix gmelinii Rupr.）在泰梅尔东部（TAY）（72°N，102°E）的永久冻土区，使用树木年轮和稳定同位素分析，为气候最佳时期（COP）4111-3806 BC和中世纪温暖时期（MWP）917-1150 AD，与最近时期（RP）1791-2008 AD进行比较。我们开发了一个描述的气候和环境变化的泰梅尔东部的树轮宽度和稳定同位素（δ 13 C，δ 18 O）数据的基础上，气候参数（温度和降水量）的关系的统计验证。此外，我们将我们新的树轮和稳定同位素数据集与早期发表的7月温度和降水重建进行了比较，这些重建是从泰梅尔半岛的喇嘛湖的花粉数据、Severnaya Zemlya（SZ）上Akademii Nauk冰帽的δ 18 O冰芯数据和格陵兰岛（GISP 2）的δ 18 O冰芯数据推断出来的。以及来自雅库特东北部（YAK）的树轮宽度和稳定碳氧同位素数据。我们发现，在TAY的COP是温暖和干燥的MWP相比，但相当相似的RP。我们的研究结果表明，MWP在TAY开始早，比牦牛湿润。根据喇嘛湖花粉数据、深圳氧同位素数据和树木纤维素中的碳同位素获得的7月降水重建结果一致，表明MWP期间气候条件较为湿润。一致的大规模模式反映在树纤维素从TAY和牦牛，SZ和GISP 2在MWP和RP的氧同位素数据之间的显着联系。最后，我们表明，最近的变暖在西伯利亚北部并非史无前例。6000年前的树木年轮、稳定同位素、花粉和冰芯数据都记录了类似的气候条件。
To answer the question “Has the recent warming no analogues in the Siberian north?” we analyzed larch tree samples (Larix gmelinii Rupr.) from permafrost zone in the eastern Taimyr (TAY) (72°N, 102°E) using tree-ring and stable isotope analyses for the Climatic Optimum Period (COP) 4111–3806 BC and Medieval Warm Period (MWP) 917–1150 AD, in comparison to the recent period (RP) 1791–2008 AD. We developed a description of the climatic and environmental changes in the eastern Taimyr using tree-ring width and stable isotope (δ13C, δ18O) data based on statistical verification of the relationships to climatic parameters (temperature and precipitation). Additionally, we compared our new tree-ring and stable isotope data sets with earlier published July temperature and precipitation reconstructions inferred from pollen data of the Lama Lake, Taimyr Peninsula, δ18O ice core data from Akademii Nauk ice cap on Severnaya Zemlya (SZ) and δ18O ice core data from Greenland (GISP2), as well as tree-ring width and stable carbon and oxygen isotope data from northeastern Yakutia (YAK). We found that the COP in TAY was warmer and drier compared to the MWP but rather similar to the RP. Our results indicate that the MWP in TAY started earlier and was wetter than in YAK. July precipitation reconstructions obtained from pollen data of the Lama Lake, oxygen isotope data from SZ and our carbon isotopes in tree cellulose agree well and indicate wetter climate conditions during the MWP. Consistent large-scale patterns were reflected in significant links between oxygen isotope data in tree cellulose from TAY and YAK, and oxygen isotope data from SZ and GISP2 during the MWP and the RP. Finally, we showed that the recent warming is not unprecedented in the Siberian north. Similar climate conditions were recorded by tree-rings, stable isotopes, pollen, and ice core data 6000 years ago.
