近几个世纪的温度重建是估计人为扰动开始之前和期间气候系统自然变率的基础。在这里，我们提出，第一次，一个独立的和物理基础上重建的平均年温度在过去的半个千年，从地下水在法国。重建的惰性气体温度（NGT）记录表明，整个16 - 19世纪的气候条件比现在更冷。暖化时期发生在17 - 18和世纪，而冷化则在世纪重建。一个值得注意的巧合与其他温度记录证明。氘过量与NGT平行变化，并表明含水层补给的季节性变化;而地下水中的高过量空气表明地下水位的高振荡时期。
Temperature reconstructions for recent centuries are the basis of estimations of the natural variability in the climate system before and during the onset of anthropogenic perturbation. Here we present, for the first time, an independent and physically based reconstruction of mean annual temperature over the past half millennium obtained from groundwater in France. The reconstructed noble gas temperature (NGT) record suggests cooler than present climate conditions throughout the 16th–19th centuries. Periods of warming occur in the 17th–18th and 20th century, while cooling is reconstructed in the 19th century. A noticeable coincidence with other temperature records is demonstrated. Deuterium excess varies in parallel with the NGT, and indicates variation in the seasonality of the aquifer recharge; whereas high excess air in groundwater indicates periods with high oscillations of the water table.
