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
and anthropogenic heats and also any 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 are efficient physical factors to
fight global warming. It is also shown that the pool of water present on
Earth is progressively augmented by the water liberated parallel to
CO2 during the combustion of fossil hydrocarbons in
which it was stored millions years ago. Water as source of hydrogen may
be an alternative to the sources of energy produced and consumed by
humanity provided that heat-cycle assessment from cradle to grave
complements the life cycle assessment favorably.
