This research consists of the study of the evolution of the glacial retreat of the Japu Punta and Yayamari snow-capped mountains in the Vilcanota Mountain Range (Cusco department) in a context of climate change. The methodology to evaluate the climate is based on identifying the existence of trends in the temperature and precipitation series, for which the regional vector method was carried out for criticism, homogenization and completion of data, the statistical tests used were Mann Kendall and regression. linear. Regarding the study of glaciers, the measurement of the glacier surface was carried out using the geomorphological criterion, on the other hand, to quantify the variation of the equilibrium line altitude (ELA), the Area x Altitude Balance Ratio (AABR) method was applied. by Omaston (2005). The results of the investigation indicate that, in the mean temperature series, the Acomayo, Pomacanchis and Paruro meteorological stations present a significant positive trend, while the Ccatca and Sicuani stations do not present positive trends; Regarding the precipitation series, there is no evidence of any kind of defined trend in all the meteorological stations. In the case of the behavior of the glaciers of the mountains Japu Punta and Yayamari, 11 glaciers were identified where a loss of glacial surface of 5.01 km2 and a rise in the altitude of the equilibrium line of 59 meters in a period of 30 years were calculated. (1992-2022) which represents a deglaciation rate of 0.167 km2/year and 1.967 m/year respectively.
