Right now, in the field of atmospheric science — there is an interesting debate going on. We’ve been in our “Solar Minimum” for more than a year now; the usual thing that happens next (in the normal 11-year solar cycle) is that sunspots (solar activity) return on the surface of the sun. However, some scientists are speculating that we might be entering a “Maunder Minimum” — which is a prolonged severely cold time on the planet.
Our last Maunder Minimum occurred between 1645 and 1715 AD (part of the Little Ice Age). We’ve had some evidence of “more extreme cold than usual” during this past year, which is a bit scary. We should know within the next ~2 years which way the sun is planning to go. ☹ 😊
Solar physicists at the ultra-warmist Potsdam Institute for Climate Impact are warning that Europe may be facing a ‘Mini-Ice Age’ due to a possible protracted solar minimum. For an institute that over the past 20 years has steadfastly insisted that man has been almost the sole factor in climate change over the past century and that the sun no longer plays a role, this is quite remarkable reports Pierre Gosselin.
Little noticed by the mainstream media in their obsession with global warming is an exceptionally chilly 2020-2021 winter in the Northern Hemisphere and an unusually early start to the Southern Hemisphere winter. Low temperature and snowfall records are tumbling all over the globe. 
Presently, snow records have continued to be broken around the world
Whether the present frigid and snowy conditions in much of the world are merely a result of La Nina, or the start of a longer cooling trend, we won’t know for several years. Climate, after all, is a long-term average of the weather over an extended period of time, up to decades.
Nonetheless, there’s ample evidence that the current cold snap is not about to let up. At the same time the UK experienced its lowest average minimum temperature for April since 1922, and both Switzerland and Slovenia suffered record low temperatures for the month, bone-chilling cold struck Australia, New Zealand and even normally shivery Antarctica in the Southern Hemisphere. The 2021 sea ice extent around Antarctica is above or close to the 30 year average from 1981 to 2010. 
Flashback to 2014, when The New York Times, a charter member of the climate crisis cabal, ran a terrifying article that predicted ‘the end of snow.’ That dire forecast preceded 14 years earlier, in 2000 by the UK Independent, another charter member of the climate crisis cabal, which reported that “Snowfalls are a thing of the past. Children just aren’t going to know what snow is.” 
For those who claimed children would not know what snow looked like — global snowfall rates have risen 3% since 1980. 
Presently, snow records have continued to be broken around the world. Belgrade, the capital of Serbia, registered its all-time high snowfall for April, in record books dating back to1888; during April both Finland and Russia reported their heaviest snow in decades; and the UK, Spain and several countries in the Middle East saw rare spring snowfalls from March to May. On the other side of the globe, up to 22 cm (9 inches) of snow fell on southeastern Australia mountain peaks a full two months before the start of the 2021 ski season; and southern Africa was also blanketed in early season snow. 
Mass deaths of reindeer have been reported across the Yamal Peninsula, Russia
In early January 2018, a powerful blizzard caused severe disruptions along the East Coast of the United States, as snow and bitter cold weather set new records, with Erie, PA shattering its all-time snowfall record. The next month, Chicago tied a longstanding record with nine straight days of snow after chalking up its most frigid New Year’s Day in history. The Plains, Midwest, and Northeast were hit with record setting frigid temperatures, and the Deep South was gripped by sub-zero freezing that dumped snow, even in Florida. 
Mass deaths of reindeer have been reported across the Yamal Peninsula, Russia. The animals forage was locked under unusually thick ice this year. Members of a scientific expedition have called for new urgent ideas to rescue herding in the region due to an increase in periodic glaciation. 
Twenty-one people, including two of China’s top marathon athletes, died after freezing rain and high winds struck a 62-mile mountain race in northwestern China on Saturday May 22, 2021. The 62-mile mountain race in Gansu Province found athletes in shorts and T-shirts facing freezing rain, hail and high winds.
Hours into the event the weather suddenly deteriorated as the runners were climbing to 6,500 feet above sea level to the 12-mile mark. Runners dressed in shorts and T-shirts were suddenly facing freezing conditions, and rain turned to hail. 
One model has projected we are entering another ‘grand minimum,’ which will overtake the sun beginning in 2020 and will last through the 2050s, resulting in diminished magnetism, infrequent sunspots production, and less ultraviolet (UV) radiation reaching Earth. This all means we are facing a global cooling period that may span 31 to 43 years. The last grand minimum event produced the mini-ice age in the mid-17th century. Known as the Maunder Minimum, it occurred between 1645 and 1715, during a longer span of time when parts of the world became so cold that the period was called the Little Ice Age, which lasted from about 1300 to 1850 AD.

Comment from an astrophysicist: My theory holds that reversals of the earth’s poles do not result from solar minima. Just the opposite. The earth’s negative pole is at the north axis because the earth orbits in a predominantly negative solar wind and rotates in the right direction to put the negative pole (south pole) of earth’s magnet at the north axis. We call it the north pole because it attracts the north pole of a compass.
Once every few hundred thousand years, the sun gets super-active. Then the more positively charges in the inner solar atmosphere come all the way out to the earth’s orbit. The positively charged region is has greater charge density because positive particles are 2000 times heavier than electrons. When that happens — the earth’s poles flip, because the rotation of the now-positively-charged earth puts the earth’s negative pole at the south axis.
However, instead of the earth getting hotter with a hotter sun, the opposite happens. Much more water is evaporated from the oceans via Compton Effect evaporation (different from thermal evaporation). Clouds rise higher and freezing occurs; ice falls and cools the lower atmosphere. The excess water precipitates as ice, rather than rain, and a new ice age builds rapidly. A very hot sun causes an ice age. Even on Venus the temperature in the upper atmosphere will freeze water. Earth is no different. When clouds rise to great heights, ice falls to the ground. Falling ice depletes the heat in the lower atmosphere.
