Abstract. The use of different primary energy sources in human society has led to two major polluting emissions in the environment: energy (mostly heat), and chemical substances (mostly carbon dioxide). In this paper, a new approach, based on the similarity between sensible heat and CO2 transfer properties, was used to determine the effect of anthropogenic heat release on the global air temperature. The total global anthropogenic emissions of sensible heat were divided into two separate streams: directly transferred to: (1) water and land, and (2) to the atmosphere. The direct emissions of heat to the atmosphere during the industrial era (years 1850–2018) were determined and their effect on the change of global atmospheric temperature was calculated. The global atmospheric temperature increase caused by anthropogenic heat emissions was estimated. The resulting calculations showed that at least half of the actual atmospheric temperature rise recorded during the last 170-year period, was due to the anthropogenic heat release. These results suggest that the temperature change of the atmosphere (global warming) is strongly affected by anthropogenic heat emissions.

Short summary
Fuel burning involves two types of emissions to the environment: CO2 and heat. Recently, increases in both CO2 and heat emissions have been taking place. So far, mostly the effect on atmospheric temperature of carbon dioxide has been studied. This paper studies the effect of anthropogenic heat on the atmospheric temperature. It was shown that approximately half of the temperature increase is due to the direct emission of heat, and the other half is due to the greenhouse gas effect.
