Abstract

Some scientists of “Anthropogenic Global Warming” (AGW), such as M. T. Boy Koff, A. M. McCright et al., claim that the increase in atmosphere of greenhouse gas carbon dioxide (CO₂) coming from anthropogenic burning fossil fuels will cause a rising of air temperature that, in a few decades, will create severe uncountable problems for mankind and the biosphere. On the contrary, other scientists who support the thesis of “Not Anthropogenic Global Warming” (NAGW), the so-called “skeptics”, such as L. Weinstain, N. Scafetta et al., affirm that the increase of CO₂ coming from the various human activities will not be able to increase air temperature in the atmosphere in such a way as to cause dangerous consequences for the biosphere. For “skeptics” the rising of temperature in the atmosphere is caused mainly by a natural mechanism of the planetary system and other natural causes not strictly connected with anthropogenic activities. Moreover, they rely on theories based on the thermodynamic and physical-chemical equilibrium on the Earth’s atmosphere and based on the variation of both CO₂ concentration and air temperatures down the ages. The aim of this paper is to demonstrate that both AGW and “skeptics” scientists, when analyzing the different problems caused to mankind and the biosphere were referring to only one of the two sides of the same medal. Based on this concept, the paper investigates:
