A lesson in interpretation of 'science' and an example of how science is used now the way religious texts were used up until the early 1900's:
The paragraph below is taken from this report, written by a 'Sir' and a Doctor. (Akin to a Bishop and a Preist I suppose)
"But these events pale in comparison to the superstorms of 1921 (which disabled telegraph services) and the Carrington event of 1859, which could cripple electrical and digital communications infrastructure around the globe if it were to happen today. Predicted contemporary impacts of a Carrington-level event include power outages to 20–40 million people in the US for durations from 16 days to one to two years, with a cost estimate in the trillions of dollars. Major and potentially lasting disruptions of space-based and earth-based critical infrastructures for communication and transportation (navigation and traffic control) and cascading impacts on other sectors are also to be expected. The likelihood of such an event is estimated between 6 and 12% in the next ten years."
The writing is specifically structured to lead an average reader to think that we face a high risk of a 'Carrington Event' in the next 10 years. Basically a 1 in 10 chance we will have 'such an event' (Remember, almost everyone would be frightened by and refuse a vaccine injection if a doctor told them "You have a 1 in 10 chance of sustaining brain damage from this vaccine" because, for the patient "the risk is frighteningly high". Which it actually is in that context. Which is the context we are 'conditioned' to.
In the case of solar weather context: If we unpack the possible meaning behind those "scientific derived numbers and statements" we might realise it means something quite different for risk. For the purpose of the arguments below lets fix the risk at 10% in the next 10 years to make the math easier.
It would appear that 10% risk means that: If we look at 10 separate decades (the next 100 years in total) it is calculated that in ONE of those decades (1/10=10%) 'such an event' will occur. And ... we don't know which one. It could be next year ... or 99 years from now. I have been alive for almost 5 decades ... I've never seen a 'carrington level event'. My grandparents and parents lived through more than 10 decades ... they never saw a Carrington level event either. Why?
Two likely reasons. Risk of an event is not evenly spaced through time. In the real world 10 carrington level events may occur in just one decade (as the sun becomes super-active for a while) and then none for the next 1000 years. Does THAT concept of risk seem more or less scary than "1 in 10 Chance?" They are scientifically identical!
Then we have to ask ourselves ... what is the meaning of the phrase 'such an event' in this report? The sentence with the numbers included in it doesn't also include the words 'Carrington Level Event effecting earth'. So is this paragraph really saying in one of the next ten decades we will experience a solar storm that disrupts infrastructure and comms to some serious level (but not specifically a catastrophic level)? Or there will be 10 'significant events in the next 1000 years'? Or even "the sun is will generate a CME that 'IS CAPABLE of causing a carrington level event' but which may or may not effect comms and infrastructure on earth depending on the direction it travels. There is a lot of information missing from the statement isn't there?
Any time we see science and numbers bandied around ... take the time to really think about what is NOT being said about how they are derived ... and what they really mean.

Depends on the historical record which is most likely sketchy in accuracy of such events. Most likely these events can only be marginally better measured more accurately today due to the industrial evolution we find ourselves in. They could happen every 100 years or 300 years or they could be just random events occurring when conditions are ripe, which leave's "science" into theory of such matters. I say measured as what measure can science evaluate events now from the historical record?

I have tried to prepare my power systems and radio gear etc for an EMP/CME with fast acting gas arresters etc, but ........who knows. I also have a spare engine computer, ignition module etc wrapped up in foil under the seat in my ute, and tools to change it out. So we can only prepare as best we can for an event that we don't know what's gong to happen as there is no precedent. Have spare radios and power system gear in a steel container. Who knows ? My main short wave radio is a WW2 Australian made Kingsley all valve set, powered from a WW2 genemotor (A 12 volt dc motor and 270 volt dc generator on the same shaft), so should be EMP/CME proof. The backup transmitter can also run from the same genemotor (the 500 volt winding) and runs about 10 watts out on all ham bands and is also valve powered, so EMP/CME proof...I hope ! One thing is that man made interference will be reduced to almost nothing after EMP, so my 10 watts should get around the world. (In the 1920's, it was common to communicate around the globe with less than 1/2 watt rf output, so 10 watts should kill it, if anybody is still left).
Do radio active cats have 18 half lives ?
