Abstract
The all-sided information provided by greenhouse gas experts is disturbing. Future ocean level and atmosphere temperature raises are assigned to an increase of "greenhouse effect" due to the surplus of carbon dioxide (CO2) of anthropogenic origin. Reducing the fossil sources of CO2 is therefore the recommended solution. However, the related dogma is subject to polemics. As an alternative, the present approach is based on the exploitation of twelve facts and not on assumptions and calculations. It is shown that a minimal estimate of the global thermal energy consumed in 2018 (0.1 Zj) and the estimated heat necessary to melt the ices that disappeared during the year (0.08 Zj) are of the same order of magnitude. This observation suggests that the greenhouse effect of fossil CO2 is not necessary to explain the disappearance of ices. The discussion shows that taking into account the generally neglected anthropogenic heat and the water phase-transfer equilibria may explain the discrepancy observed between the rather small variations in average atmospheric and oceanic temperatures and the considerable ices melt. It is shown that the increases of total energy, of anthropogenic heat and of melted ices exhibited the same trends over the 2000-2018 period of time. A few years should be enough to confirm or invalidate these trends. In case of confirmation, replacing the fossil sources of energy by other sources to limit climate changes may turn to be ineffective if these new sources supply equivalent amounts of heat. It is the controls of population and of its bulimia in energies that will have to be promoted.
