NASA: Revisiting Our Vulnerabiity To Solar Flares

A nice way to let everything collapse and blame it on the sun.


NASA: Revisiting Our Vulnerabiity To Solar Flares (ZeroHedge, Oct 27, 2014):

Elliott Capital’s Paul Singer has previously raised his concerns that there is one risk that stands way above the rest in terms of the scope of potential damage adjusted for the likelihood of occurrence – an electromagnetic pulse (EMP). Different initiators of EMP have different pulses and different effects. But the bottom line is that EMP fries electronic devices, including parts of electric grids. In 1859, a particularly strong solar disturbance (the “Carrington Event”) caused disruption to the nascent telegraph network. It happened again with similar disruptions in 1921. Now, as Dr. Lika Guhathakurta discusses, “to bring our modern society to a halt, I don’t think we need an event that is as large as a Carrington Event. It could be much smaller, simply because of the connectedness of our power grid and also the entire technological system.

The biggest sunspot on the face of the sun in more than two decades unleashed a major flare on Friday (Oct. 24), the fourth intense solar storm from the active star in less than a week.

Last year, we recorded a fascinating interview with Dr. Lika Guhathakurta, NASA astrophysicist and heliophysics expert, to understand the science behind coronal mass ejections (CMEs — also commonly referred to as ‘solar flares) and the potential havoc a large one could wreak on our technology-dependent society. The largest CME recorded in modern history, the Carrington Event, occurred in 1859 and it’s charged particle wave brought down the then-new telegraph system across the US.

Dr Guhathakurta returns to the podcast this week to discuss a large-scale CME that nearly hit Earth back in July of 2012 (a direct hit missed us by about 1 week), as well as to discuss the strengths and weaknesses of the warning system we have in place to alert us to such dangers, and the continuing vulnerability our system have to such an event:

To bring our modern society to a halt, I don’t think we need an event that is as large as a Carrington Event. It could be much smaller, simply because of the connectedness of our power grid and also the entire technological system. We don’t know how to operate without our GPS system.

What’s interesting is that we used to think that this kind of low-probability, high-impact event happens every 100 years or so. Some researchers are doing calculations that suggest that the probability could be much higher: 10-12%. Now, that probability that they are referring to is that a solar storm will be that severe. But as to its impact — we still know very little about that.
