<p>Environmental and energy issues are crucial to social development. CO₂ geological storage and coalbed methane mining (CBM) both depend on the coal-rock–gas interaction, which is temperature-dependent. This work discusses the thermal effect features of gas adsorption and desorption in coal rock to better understand the relationship between these processes and temperature. The interaction between gas adsorption and desorption and temperature in coal rock was further analyzed. The influencing factors of temperature change of coal-rock–gas interaction were thoroughly analyzed, including factors related to coal rock itself and environmental conditions. The contact and non-contact measurement techniques of temperature change during coal-rock–gas interaction are introduced, as well as the current use of temperature-change methods to either encourage or inhibit gas adsorption and desorption in coal rocks. Lastly, it is suggested that more research on the temperature changes during the interaction between coal rock and gas can shed light on the mechanisms of gas adsorption and desorption in coal rock. This will help to establish the theoretical foundation for theories related to temperature that will be applied to low-temperature fixed-point sampling, heat-injection-enhanced CBM mining, and CO₂ geologic storage. The outcomes covered in this research are crucial for enhancing environmental preservation and energy use efficiency.</p>
