“…The temperature in the topsoil, rather than in the air, ultimately determines the distribution and productivity of most terrestrial species, as well as many ecosystem functions at or below the soil surface [33][34][35][36]. Voropay et al [2] demonstrated that changes in vegetation cover caused by anthropogenic factors, as well as changes in soil moisture, its morphological structure and granulometric composition of the upper layer, lead to a change in the temperature regime of permafrost and its degradation with decreasing its upper limit. The soil under the fallow warms up better and cools down faster than under the spruce forest.…”

Significant changes in the thermal and physical state of soils are also associated with anthropogenic factors: deforestation, fires, soil plowing, cattle grazing and other types of impact that affect the biological, food and water-air regimes of soils [2].…”

Changes in key climate index affect ecosystems and biodiversity. In this regard, the assessment of the climatic conditions is of particular relevance. This study presents the results of an analysis of climate change and digital mapping of soil temperature in the Yangan-Tau UNESCO Global Geopark (Russia). The steady increase in air temperature was revealed, which causes an increase in the sum of active temperatures and the duration of the warm period of the year. Annual total precipitation during 1966-2020 changed the sign of the trend: positive trend (increase in precipitation) in 1966-1990, while in 1991-2020 is negative. The hydrothermal indicators determined the increase in aridity during the warm period. Based on the analysis of changes in the climatic conditions of the geopark, a comparison was made of the temperature regimes of air and soil, and the relationship between these indicators in the snow-free period was revealed (R2 = 0.62). An approach is presented for digital mapping of the temperature regime of the surface layer of soils based on ground-based research data and the results of interpretation of the Landsat thermal bands. A significant relationship between soil temperature and Earth surface temperature for the snow-free period was revealed (R2 = 0.83). Based on the obtained regression model and Landsat 8-9 data for the snow-free period of 2013-2022 the map of the distribution of average temperatures of the surface layer of soil from May to October was produced, which clearly demonstrated the relationship between soil temperature and biomes.
