Refrigerator as Model of How Water Manages Solar and Anthropogenic Heats and Controls Global Warming

Abstract : The role of anthropogenic carbon dioxide (CO2) in global warming and climate change is confusing. Experts in greenhouse effects predict that changes in ocean level and atmospheric temperature, which are still presently very small, will increase considerably in distant future. On the other hand, the loss of ices is already dramatic. Greenhouse gases, in particular CO2, are said responsible for the global warming but they do not explain the dominance of ice loss relative to atmosphere and ocean temperature increases. On the basis of chemical and physical fundamentals, it was previously shown that the anthropogenic heat released between 1994 and 2017 has provided enough heat to cause the melting of a large part of the global ice lost during the same long period. To go farther, the present contribution compares the management of solar heat on Earth with the thermodynamic cycle used to control the temperature inside refrigerators. The discussion shows that solar heat and anthropogenic heat are managed similarly using water as refrigerant and that the equilibria between water physical states (ice, liquid and vapor) are buffering phenomena relative to climate changes. It is also shown that the combustion of fossil hydrocarbons is releasing a huge amount of water that has been stored for millions of years as hydrogen in hydrocarbon fossil sources of energy. However, this extra water remains minor compared with the water issued from global ice imbalance. The last part proposes to use heat-cycle assessment from cradle to grave as means to compare different energy sources in the search for ways to minimize anthropogenic heat release and possibly global warming. Water electrolysis could then be a climate- and environment-friendly source of renewable hydrogen-based energy provided the electricity necessary to generate hydrogen can be produced on a large scale with better heat-cycle and life-cycle than traditional sources.
