The paper researches the adaptation of ancient people to climate change and their influence on the surrounding landscapes on the example of the Surungur archaeological site (Southern Kyrgyzstan). The charcoal interlayers from Surungur depositions (excavations of 2021) were studied by the method of macrocharcoal analysis. Charcoals of different types were found in the samples: wood, grass, charred bones and amorphous charcoals. Amorphous coals are coals without a visible ordered structure with inclusions of other type macrocharcoals and containing spherulites. Spherulites are spherical crystals of calcite (5–20 mkm) formed in large quantities in the digestive system of ruminants (cows, sheep, goats, deer), preserved during combustion and visible in polarized light under a microscope. Based on the reconstruction of the used fuel types and the comparison of the data on climate in different time periods, we can conclude that throughout the period of the sites’ existence, ancient people used all types of fuel. During periods of warm and humid climate, trees were readily available and wood was mainly used, while during periods of dry and cold climate dung and probably bones were used more.
