A Mini Ice Age Is Coming? New Research Reveals The Sun Will Lose 7% Of Its Power In About 30 Years

A new scientific study has just been published that
illustrates a phenomenon known as the solar “grand minimum.”

Also, known as the “prolonged sunspot minimum,” it’s a
period when the Sun’s magnetic pull will diminish, sunspots will be much less
frequent, and less ultraviolet radiation will make it to planet Earth — all due
to random fluctuations in the Sun’s magnetic field. All of that can mean
unusually cool temperatures for us, and it’ll also make the Sun appear dimmer.

The Sun is on an 11-year up/down cycle as it is, but this
grand minimum will be especially cold, as the Sun’s activity will go lower than
the regular 11-year low. That translates to colder temperatures for parts of
the world.

How cold? Predictions, based on a study of previous sunspot
reductions preceding a grand minimum period, are that we’ll see a 7% reduction
in the Sun’s light and heat — and remember, that’s 7% lower than the lowest of
the 11 year cycle that we usually see.

Such a grand minimum happened in the middle of the 17th
century. Known as the “Maunder Minimum” (from the names of 2 well respected
solar astronomers of the time, Anne Russel Maunder and Edward Walter Maunder),
the resultant cold temperatures saw the river Thames freeze, and the Baltic Sea
as well — which allowed a Swedish army to invade Denmark by marching across the

At the same time, Alaska and Southern Greenland warmed, due
to the thinning of the Earth’s stratospheric ozone layer, which changes wind
and weather patterns around the world.

The exact date and severity of the event is still in
question, but the clues all point to things bottoming out around the year 2050.
It could start as soon as 2030, however. Just for reference, the Maunder
Minimum lasted from 1645 until about 1715.

Will it save us from global warming? The very same
scientists don’t think so.

“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,” according to the study.

I have my own prediction: If I’m still alive by then, I’ll
be heading to Jamaica.
