Borehole paleothermometry, a reconstruction of the past ground surface temperature change from subsurface temperatures, is an important tool for understanding climate responses to conditions of a certain area in the past. Based on the close relation between glacier inner temperature and surface temperature change, glacier surface temperature variation process can be reconstructed by the borehole temperatures. Because of firnification and ice flow, the climate reconstruction from glacier borehole temperatures is more difficult than for other places such as permafrost. The coupled heat transfers and ice-flow equation and relative inversion algorithm are the theoretical basis and the key method of study on paleoclimate reconstruction by glacier borehole temperatures. In this study, we collected publications about the reconstructions of paleoclimate by glacier borehole temperatures over the last three decades, and reviewed some progresses in these areas. The advantages and disadvantages of different inversion algorithms (trial and error, control methods, Monte Carlo inverse modelling and the Tikhonov regularization method) were briefly introduced and discussed. Although the relationship between borehole temperatures and the climate may be affected by many factors (solar radiation, melt water, and so on), the cold glacier borehole temperatures in polar and high latitude regions can reflect the climate change well. At present the history of climatic changes has been reconstructed on different time scales in the world since the Last Glacial Maximum. Meanwhile, the reconstructed results using glacier borehole temperatures and the climate records in the ice core are able to confirm one another. In addition, by analyzing the glacier borehole temperatures and instrumental records, we can obtain a general understanding of the glacier-climate interactions and predict the response of glacier to climate change. However, less research has been done on the reconstruction of paleoclimate by cold glacier borehole temperatures for the middle latitude regions, and strengthening the study in these areas can help to reveal the climate change at middle latitude with high altitude.

Key words: glacier borehole temperatures, climate change, heat transfer and ice-flow equation, temperature reconstruction
