8. Conclusion
The mechanism by which the temperature in a refrigerator is controlled appeared a rather consistent model of how the average temperature of the global environment may be controlled if water is given the role of refrigerant with: - ice melting and water evaporation as heat absorbing phenomena, - chaotic climatic events like hurricanes, tornadoes, ocean streams and humid air ascension to move the warm vapor to condensation zones as the compressor does in a refrigerator; and - clouds as source of radiative elimination to space of the transferred heat they release because of water condensation. Accordingly, surface temperature and thus sea level rises should be smaller than IPCC’s calculated values for the next decades. In contrast, climatic events (flooding, drought, local temperatures, etc.) should increase in strength or magnitude and frequency if human population and its standard of living continue to grow and generate more and more anthropogenic heat release, regardless of its origin. In terms of thermodynamics, the refrigerant role of Earth’s water appears a credible means to avoid heat accumulation on Earth and promote radiative elimination to space. The predominance of radiative forcing relative to anthropogenic heat releases suggested that 2018 ice imbalance should have been much larger than observed except if evaporation is taken into account or if scientists who deny radiative forcing turn to be right. In parallel, the amount of liquid water stored for millions of years in fossil hydrocarbons and released by combustion was shown negligible relative to the amount generated by disappeared ices. In the future, the contribution of anthropogenic heat residue of energy sources could become no longer negligible if the deny of CO2 as source of radiative forcing defended by some specialists of electromagnetic radiations is recognized. Presently, relying on the reduction of carbon-containing sources of energy may appear insufficient to limit climate evolution and ice imbalance growth if the replacing sources of energy, including water as source of hydrogen, generate similar amounts of waste heat. Heat amounts and heat transfers estimated in the present essay will have to be assessed more precisely by suitable interdisciplinary consortia attempting to understand and to take into account the complexity of Earth like biologists are doing for the human body.
