This study investigates the potential implementation of geothermal systems in Central Brazil, focusing on historical and future soil temperature conditions. The soil's distinct thermophysical properties result in a slower response to climatic variations, creating a temperature gradient known as soil thermal inertia. The research analyzes soil temperature correlations with altitude and climate change in selected Mato Grosso municipalities for historical, 2050, and 2080 periods. The findings reveal a robust correlation between altitude and historical soil temperature, indicating varied geothermal potential. However, 2050 and 2080 projections show significant potential reduction due to climate change impacts, especially in lower-altitude regions. The positive correlation between soil and air temperatures highlights their close relationship, crucial for assessing geothermal potential under climate change. The results emphasize the importance of considering climate projections in geothermal planning and suggest geothermal energy as a sustainable cooling solution for Mato Grosso's agricultural buildings, adapting to evolving thermal conditions.
