Because of the intese, harsh winter we have been experiencing, NASA scientists recently released information indicating that sunspot activity on the sun is diminishing to a decades long low. Sunspots are the formations on the sun’s surface that generate CME’s, or Coronal Mass Ejections, which can emulate the effects of a weapon or manmade generated EMP.
A CME is comprised of superhot gasses, photonic particles, radiation, and extremely strong magnetic waves. It has mass. The mass and velocity, as well as the nature of the magnetic component of a CME causes the Earth’s magnetic field to warp and bend. It is literally pushed out and away from the Earth’s sun facing side. Think of a tree standing in a feild. A strong wind from a single direction pushes against the tree’s canopy. causing the entire tree to sway, and the limbs to bend back in the direction of the flow of the wind. Most trees can stand a pretty consistent high speed wind. It is when there are gusts and eddies and sudden changes in wind speed and direction that can cause a tree to snap off or break under the stress.
The same can be said for the Earth’s magnetic feild. It will be pushed back in the direction the CME is pushing, but a CME is not nessecarily steady as far as strength and speed. There are variations. It is when the Earth’s magnetic field is warped out and away under high pressure from a CME then the pressure abates suddenly that causes the first “pulse”. The snapping back of the Earth’s magnetic field generates an electro-magnetic pulse that can, has, and likely will affect delicate electronics in the same fashion as a nuclear weapon EMP would. Research the “Carrington Event” for an idea of how severe a CME can be.
That being said, the lessening of solar activity not only serves to cool the planet significantly, it also greatly reduces the threat of a CME/EMP event. That does not mean the threat is removed, it just lessens the chances of an EMP event occuring due to “natural causes”.
In Part 3, I will discuss the continuing possible effects of an EMP event on the populace of the US.
