During a Grand Solar Minima the upper atmosphere becomes more charged from very high energy galactic and intergalactic cosmic particles hitting the earth's upper atmosphere.
In this high altitude balloon testing chart from spaceweather.com, you can see that cosmic ray intensity has hit historic high levels in 2018.
One of the effects of increased cosmic rays is the upper atmosphere high speed jet streams at the North and South Poles start to wander more frequently from their normal relatively stable course.
As the Northern Hemisphere jet stream wanders South, it draws cold Arctic air with it, and on the other side of this much warmer tropical air can be drawn from the tropics much further North.
In this image you can see what a stable jet stream looks like compared to a polar vortex event.
During a polar vortex event, a country as large as the US could have part of the country experiencing a heat wave, while the other part will be experiencing record cold temperatures.
This image shows how a solar vortex can create enormous temperature differences. Where the very hot and very cold air masses meet, you will see extreme weather events occur.
Grand Solar Minima are historically associated with dramatic weather events. Examples are massive hail events, a year or month's worth of rain falling in a day, record snow, record hot and cold temperatures, plus way above the normal number of lightning strikes during storms. Tornadoes can appear in regions where you would not expect to see them. Deserts can see massive flooding or even snow, while other areas that are normally wet can experience droughts.
These earth changes happen so quickly and dramatically that farmers can't cope. This leads to massive crop losses, as we can see presently occurring on the worldwide crop loss map below. Click the map markers to get report details. These worldwide crop losses have been created by rapid and dynamically changing weather conditions, cold, heat, flooding, snow, hail and drought etc., over the last 12 months. As we go deeper into a Grand Solar Minima, crop losses will intensify, because of an increasing number of volcanic eruptions and earthquakes that are also triggered by the increasing cosmic rays intensity.
There is a lot of scientific discussion at present on how extreme this Grand Solar Minima will be. Will it be similar to a milder Dalton, (years 1790 1820), or more like the extreme Maunder Minima (years 1645 1715). There is the possibility that this Grand Solar Minima will be even more extreme than both of these recent past Grand Solar Minima. The strength or weakness of the next eleven year solar cycle will provide an indication. The number of Sun spots define what is a minimum or maximum for a solar cycle.
Most governments are not up to speed on this new dynamic, and this will lead to a lot of people dying and worldwide instability because there have not been significant preparations put in place. We know what happened in the past during Grand Solar Minima. It is all there in plain sight in the historical record for anyone who takes the time to do some basic research on the subject.
