| description | <p>Ice cores from the Tibetan Plateau (TP) are widely used for
reconstructing past climatic and environmental conditions that extend beyond
the instrumental period. However, challenges in dating and interpreting ice
core records often lead to inconsistent results. The Guliya ice core drilled from the northwestern TP suggested a cooling trend during the mid-Holocene based on its decreasing <span class="inline-formula"><i>δ</i><sup>18</sup>O</span> values, which is not observed in other Tibetan ice cores. Here we present a new high-resolution <span class="inline-formula"><i>δ</i><sup>18</sup>O</span> record of the Chongce ice cores drilled to bedrock <span class="inline-formula">∼30</span> km away from the Guliya ice cap. Our record shows a warming trend during
the mid-Holocene. Based on our results as well as previously published ice
core data, we suggest that the apparent discrepancy between the Holocene
<span class="inline-formula"><i>δ</i><sup>18</sup>O</span> records of the Guliya and the Chongce ice cores may be
attributed to a possible misinterpretation of the Guliya ice core
chronology.</p> |
