Plain language summary
Today, successive IPCC global warming-related reports predict dramatic atmosphere temperature and ocean rises in rather distant future. These evolutions are assigned to anthropogenic greenhouse gas, notably carbon dioxide, generated by fossil sources of energy exploited in the world. However, everybody can observe that heat is also generated directly in the low atmosphere by the exploitation and consumption of all sources of energy and not only fossil ones. Production of electricity and its exploitation by cars, trains, planes, electric appliances, wildfires, etc.… heat the entire environment. The present work compares the management of solar and heat released in the environment to the mechanism that controls the temperature in the interior of a refrigerator. It is concluded that water plays a role of refrigerant via ice melting and evaporation-condensation phenomena and manages solar and anthropogenic heats similarly. According to the present study and in contrast to present predictions, the global temperature should not raise as much as predicted by IPCC. In contrast, cloud formation, rains, winds, storms, hurricanes, etc. should increase in frequency and damages. Hydrogen is proposed as alternative to fossil sources of energy. However its potential must be assessed positively relative to both thermal and environmental impacts.
