This is brand study in the field of science that has been recently posted which describes a phenomenon that is referred to as the solar “grand minimum.” It is sometimes called the “prolonged sunspot minimum” as well, and it is a timespan that occurs whenever the magnetic pull of the Sun begins to diminish. When it happens, we see fewer sunspots, and there is less ultraviolet radiation that is reaching the Earth’s surface. This is because of random fluctuations in the magnetic field of the Sun. All of this scientific activity results in cooler temperatures for those of us on Earth, and it will also cause the Sun to look dimmer.
Periodicity of the Sun
Presently, our Sun is engaged in an 11-year up/down cycle, however this grand minimum is going to be particularly cold, as we will see the activity of the Sun sink lower than its normal 11-year low. And this will translate to much cooler temperatures for certain regions of the world.
Exactly how cold will it get? Forecasts which are based on studies of prior sunspot reductions that have preceded a grand minimum period, are saying that we will see about a 7% reduction in the Sun’s heat and light. And we need to keep in mind that this is 7% lower than the low point of the Sun’s normal 11 year cycle that we have typically seen.
History of the Grand Minimum
This is kind of grand minimum happened previously during the mid-1600s. It was referred to as the “Maunder Minimum” (it was actually named after 2 very well respected astronomers of their time, who were Edward Walter Maunder and Anne Russel Maunder), the cooler temperatures of the times witnessed the freezing of the Thames river, and also the Baltic Sea — which actually let a Swedish army invade Denmark as they marched right across the ice.
And at the very same time, they observed the warming of Alaska and Southern Greenland, because of the thinning of the stratospheric ozone layer over the planet, which resulted in changes of weather and wind patterns all throughout the world.
As far as predicting the precise date and even the event’s severity, that is still a bit of a mystery, but clues are all pointing to everything reaching its bottom sometime around the year 2050. This event could actually begin as early as 2030. In case you are wondering, the previous Maunder Minimum took place from the year 1645 until around 1715.
So is this going to help save us from the effects of global warming? These very same scientists do not believe this will be true.
“The cooling effect of a grand minimum is only a fraction of the warming effect caused by the increasing concentration of carbon dioxide in the atmosphere,” as stated in the study.
