全球水循环对全球地表温度变化的响应仍然是未来气候预测和过去气候重建中的一个突出问题。降水、大气降水和海水的稳定氢氧同位素组成是从微物理过程到全球尺度的综合过程，在跟踪全球水文气候变化方面具有独特的地位。在这里，我们评估全球水文气候在过去的2,000年使用全球分布的汇编代理δ降水，δ MW和δSW。我们发现，全球平均地表温度在过去的两千年里对全球δ降水和δ MW产生了一致的影响，这是由全球海洋蒸发和凝结过程驱动的，在小冰期（1450-1850）期间数值较低，在人为变暖开始后（~1850）数值较高。太平洋步行者环流是区域变率的主要来源，特别是自1850年以来。我们的研究结果表明，随着地球变暖和变冷，全球降水和大气环流模式在几十年内迅速调整。
The response of the global water cycle to changes in global surface temperature remains an outstanding question in future climate projections and in past climate reconstructions. The stable hydrogen and oxygen isotope compositions of precipitation (δprecip), meteoric water (δMW) and seawater (δSW) integrate processes from microphysical to global scales and thus are uniquely positioned to track global hydroclimate variations. Here we evaluate global hydroclimate during the past 2,000 years using a globally distributed compilation of proxies for δprecip, δMWand δSW. We show that global mean surface temperature exerted a coherent influence on global δprecipand δMWthroughout the past two millennia, driven by global ocean evaporation and condensation processes, with lower values during the Little Ice Age (1450–1850) and higher values after the onset of anthropogenic warming (~1850). The Pacific Walker Circulation is a predominant source of regional variability, particularly since 1850. Our results demonstrate rapid adjustments in global precipitation and atmospheric circulation patterns—within decades—as the planet warms and cools.
