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.
