In the first place, as all geologists know, talking about climate change is equivalent to saying nothing. On Earth, climates have changed throughout their history. In different times and places there have been, hot, humid, arid, cold climates, glacial ages, etc. In successive geological periods there are numerous rock formations that bear witness to them. Therefore, talking about "climate change" is like saying nothing new.

Regarding the terminology also used, although to a lesser degree, there is talk of global warming, of melting of the Antarctic, of a rise in the level of the oceans, of tropicalization of temperate climates, of increase in the number of hurricanes and other analogous phenomena which would be (is stated) the result of this “warming” that is predicted.

On each of these phenomena there are contradictory data. To begin with, it is very difficult to demonstrate warming with traditional methods of measuring temperature (meteorological stations of heterogeneous distribution that tend to measure predominantly the influence of urban islands).
