It’s ironic that I chose to talk about this today – since we have a Solar storm on its way to Earth. However, today’s Solar EMP will be comparatively insignificant.
This is not to say that it will be small.
WASHINGTON (AP) — The largest solar storm in five years is racing toward Earth, threatening to unleash a torrent of charged particles that could disrupt power grids, GPS and airplane flights.
The sun erupted Tuesday evening, and the effects should start smacking Earth between 1 a.m. and 5 a.m. EST Thursday (0600 GMT and 1000 GMT), according to forecasters at the U.S. government’s Space Weather Prediction Center. They say the storm, which started with a massive solar flare, is growing as it speeds outward from the sun.
But, for all it’s power, it will be NOTHING like what might be coming. According to some scientists, we have a 12% chance of being hit with a massive ‘Carrington Event’ sized solar flare that will crash everything – WITHIN THE NEXT TEN YEARS.
That’s a one in eight chance between now and 2022.
Now, you might think of those odds as being pretty good. But, would you get on an airplane if you knew that there was a one in eight chance that it will crash and kill everyone on board? Even a one in eighty chance?
No, I didn’t think so.
I think that it’s time to prepare, don’t you?
According to a recent study published by Space Weather: The International Journal of Research and Applications, we have roughly a 12% chance of getting hit with a solar storm so powerful that it could take down the national power grid and yield catastrophic consequences for the general population. Pete Riley, a senior scientist at Predictive Science in San Diego, is the author of the study which looks at the probability of the occurrence of extreme weather events:
Probability of a Carrington event occurring over next decade is ~12%
Space physics datasets often display a power-law distribution
Power-law distribution can be exploited to predict extreme events
By virtue of their rarity, extreme space weather events, such as the Carrington event of 1859, are difficult to study, their rates of occurrence are difficult to estimate, and prediction of a specific future event is virtually impossible. Additionally, events may be extreme relative to one parameter but normal relative to others. In this study, we analyze several measures of the severity of space weather events (flare intensity, coronal mass ejection speeds)…
By showing that the frequency of occurrence scales as an inverse power of the severity of the event, and assuming that this relationship holds at higher magnitudes, we are able to estimate the probability that an event larger than some criteria will occur within a certain interval of time in the future. For example, the probability of another Carrington event occurring within the next decade is ∼12%.
The 1859 Carrington Event, as described by Wired Science, may have been a marvel to observers and caused some setbacks in the developing telegraph infrastructure at the time, but a similar occurrence today could be a global game changer:
At the time of the Carrington Event, telegraph stations caught on fire, their networks experienced major outages and magnetic observatories recorded disturbances in the Earth’s field that were literally off the scale.
In today’s electrically dependent modern world, a similar scale solar storm could have catastrophic consequences. Auroras damage electrical power grids and may contribute to the erosion of oil and gas pipelines. They can disrupt GPS satellites and disturb or even completely black out radio communication on Earth.
During a geomagnetic storm in 1989, for instance, Canada’s Hydro-Quebec power grid collapsed within 90 seconds, leaving millions without power for up to nine hours.
The potential collateral damage in the U.S. of a Carrington-type solar storm might be between $1 trillion and $2 trillion in the first year alone, with full recovery taking an estimated four to 10 years, according to a 2008 report from the National Research Council.
The post-storm effects of such an event are underestimated by the majority of the world’s population, including our political leadership. Like an electro magentic pulse attack, according to the National Research Council a massive enough solar storm could have long term effects that ”would likely include, for example, disruption of the transportation, communication, banking, and finance systems, and government services; the breakdown of the distribution of potable water owing to pump failure; and the loss of perishable foods and medications because of lack of refrigeration.”
