Global warming.


The Sun (from N.A.S.A.).

The Media and the Scientist (almost all of them) tells us that CO2 is the main cause of the increase in terrestrial temperatures.

Well, in 2022, China emitted 32.2% of the world's CO2 and India 7.4%.
Also in 2022, per capita CO2 emissions by nations saw the Persian Gulf states firmly command this global ranking.

Furthermore, there have been historical periods in which the average temperature was higher than the current one:
1) the so-called “Roman warm period” which lasted approximately from 250/200 BC. to 400 AD and during which the climate in the Mediterranean and North Atlantic area was significantly warmer (1.5-2 C°) than the current climate and, in any case, the warmest in the last 2,000 years.
2) the so-called “medieval warm period” which lasted approximately between 900 AD and and 1250 AD. and during which global temperatures are assumed to have been 1-2°C warmer than today.
It is clear to anyone that during the so-called “Roman warm period” and the so-called “medieval warm period” human production of CO2 was practically zero.
It is clear to anyone, therefore, that climate variations depend only in part on variations in terrestrial CO2 and that they also depend, for example, on variations in the Earth's orbital eccentricity, on variations in the inclination of the Earth's axis, on equinoctial precession, on variations in solar energy input, on volcanic activity, on ocean currents, etc..

In any case, it is not clear what is the logic according to which the Swedish girl (elected by popular acclaim as the leader of environmentalism despite having four diagnosed psychiatric desorders - Selective mutism, Obsessive-compulsive personality desorder, Attention deficit hyperactivity desorder, Asperger's syndrome - and despite the fact that it is even lacking even of a high school diploma) as well as her most recent emulators do not all go to protest in Beijing or the Persian Gulf instead of limit themselves hypocritically to grimacing to Trump or of blocking traffic in London or Roma.

Electric cars



Michelangelo Bonarroti: "The creation of Adam" (1512)

In 2035 in Europe there will be a ban on the production of cars with combustion engines.

Well, who is going to spend €200,000 on a Ferrari with an exclusively electric traction? A roarless Ferrari will be like a smokeless cigarette!

And, then, the current refueling plants they will find advantage to converting into electricity refueling plants, given that, unlike fuels, users will also be able to refuel at home (also having logistical convenience to do so, given that the refueling of electricity has an enormously longer duration than refueling of fuels)?

And, on journeys of a few hundred kilometers (that is, when it will be necessary to make a robust recharge of electricity), who ever will wants to travel knowing that it will force him to be forced to carry out a complete recharge (in an anonymous refueling station lost on the motorway) theoretically in over half hour (the time of the fastest battery chargers): theoretically it, because the recharging times much higher than the fuel ones will create an inevitable overlapping of vehicles and an increasing accumulation of delay.

And what will be the fate of the big oil multinationals (and of the nations that have built their own economy exclusively on the oil economy)? The implementation of emerging markets such as China and India (producers of a 40% of the world's annual carbon dioxide pollution) will be enough to compensate for European losses, given that even in those markets there are ever more urgent problems of pollution linked to economic development based on fossil fuels?

And, again, if the national electricity grids go haywire in the summer because they cannot bear the simultaneous switching on of the air conditioners, how is it possible to think that they will be able to bear a much greater demand such as that arising from distributors of recharching for electric vehicles?

And, given that half of the batteries are already produced in China today and that China's productive role in this production is destined to grow, what will be the political-strategic cost that the democratic West will have to pay for this dependence?
