Still following the post above, about an article published in The Economist that concerns the occurrence of new world catastrophes and also concerns the unpreparedness of the Governments (unpreparedness that in my opinion is almost criminal, when we take into account the fact that the expenditure in military expenses amounts to 3 trillion dollars each year) it is worth remembering that this month NASA mentioned that the Sun entered a new cycle during which it will have more solar flares: "The panel expects sunspot or solar flare activity to peak over the next five years. Elsayed Talaat, NOAA’s director of planning and analysis said if solar flares — bursts of electromagnetic energy out of the sun — are big enough, they can cause serious problems on Earth" https://www.voanews.com/science-health/us-experts-say-solar-storms-likely-upswing
