Abstract:
The relation between global warming and the role of anthropogenic carbon
dioxide (CO2) is confusing. Ocean level and atmospheric
temperature rises are predicted dramatic in distant future whereas
global ices disappearance is already dramatic and increasing. In this
article, we called on the heat control machinery exploited in a
refrigerator to show that water behaves as a refrigerant to manage
solar, anthropogenic heats and also non-solar heat generated from
sources localized on Earth. Year 2018 was taken as example for
quantitative evaluation of heat energy transfers involved in water
phases and interphase exchanges. It was concluded that ice melting and
evaporation-condensation equilibria should keep the global average
temperature relatively unchanged in the future whereas local chaotic
climate perturbations ensuring heat dispatching and temperature
averaging should increase in strength and frequency. It is also shown
that the water stored in fossil hydrocarbons is liberated as hot vapor
during combustion and returns to the global pool of water once
condensed. Hydrogen may be an alternative to the sources of energy
consumed by humanity provided that heat-cycle assessment from cradle to
grave complements the life cycle assessment favorably.
