Always protagonists in the argumentative repertoire of curious people, independent analysers, scholars, conspiracy theorists and free thinkers, the famous "Chemtrails" could emerge from the literature of counter-information to become part of tangible reality. No longer a borderline theme, therefore, but a conscious human activity.
What is this?
The scientific journal PNAS (relaunched instantly by the more widespread Popular Mechanics) has published joint studies by American, Scandinavian and Chinese scientists based on scenarios that effectively constitute speculation on the opportunity of carrying out geoengineering by adding sulphate ions to aircraft fuel , to spray the stratosphere and mitigate the effects of climate change.
In other words, it would be a matter of 'imitating' the behavior of volcanoes: in one scenario, 5 billion tonnes of sulphates per year are expected to be released into the atmosphere for 50 years.
In the second model, the expected amount of sulphates is 10 billion tons per year for 50 years, to balance CO2 production as much as possible. In this second case, taking into account two factors (the increase in CO2 despite all the protocols discussed and signed and the increase in the frequency of Katrina-type hurricanes in the next 30 years) the effects of climate change on coastal cities would be reduced by 50%.
How much is 10 billion tons of sulfates per year?
The equivalent of the 1991 Pinatubo volcano eruption every two years.
How much would these operations cost?
Around 9 billion euros per year.
Geoengineering through these “chemtrails” would in other words reduce the impact of higher sea levels on coastal cities. The risk of flooding will increase significantly, given the increase in sea temperatures: spraying the stratosphere with sulphates would produce effects mainly in the polar regions: the studies were carried out through 8 climate model simulations combined with the history of temperatures and frequencies of hurricanes from 1923 to present.
The debate will not stop in any case: some will say that the recent studies I am about to mention are a first, partial "ex post" admission of an activity already activated, others will think that it is a "coverage" operation to clear the topic and those who will think that nothing new is moving in the heavens.
