英文摘要	The unavailability of weather records from the orography dominated high Himalayas restricts our understanding in long term perspective. However, remote high-altitude regions of Himalaya silently testify the regional climate and can provide valuable insights of real climatic challenges in the absence of instrumental observatories. The tree-species over such high-altitude regions with negligible anthropogenic pressure have the potential to reveal the clear climate upheavals in long-term perspective. In the present study tree-ring samples of Himalayan birch from a high-altitude cold-arid region of Lahaul-Spiti, Himachal Pradesh were analysed and two ring-width chronologies were developed. The response function analyses showed direct relationship between the summer temperature and ring-width chronologies of Himalayan birch. Using the relationship we have reconstructed mean summer temperature (June-July) back to AD 1752 for the Lahaul-Spiti region of Himachal Pradesh. We have developed the first record of summer temperature from the Indian western Himalaya using tree-ring-width chronologies that have direct relationship with summer temperature. Further, our study in accordance with instrumental as well as other tree-ring based summer temperature records suggested that the high-altitude western Himalaya is not warming unprecedently during summers. However, slight warming pattern have been observed in the summer temperature in the later part of the reconstruction. The temperature reconstruction also reflects strong spatial correlation with gridded temperature for the western Himalaya.
