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.
