Anonymity is priceless!
Try not to overthink Global Warming!
It is a bit difficult to understand how the pressure from warm winds rushing north can move arctic air around, like it did a couple of weeks ago here in the US, breaking low temperature records across the US.
Anyway someone smarter than I can explain it. I don't even try to understand it anymore.

Upcoming Grand Solar Minimum Could Wipe Out Global Warming for Decades
Unknown to most people except those with an interest in solar science, the sun is about to shut down. Well, not completely – we’ll still have plenty of sunlight and heat, but the small dark blotches on the sun’s surface called sunspots, visible in the figure below, are on the verge of disappearing. According to some climate scientists, this heralds a prolonged cold stretch of maybe 35 years starting in 2020, despite global warming.
How could that happen? Because sunspots, which are caused by magnetic turbulence in the sun’s interior, signal subtle changes in solar output or activity – changes that can have a significant effect on the earth’s climate. Together with the sun’s heat and light, the monthly or yearly number of sunspots goes up and down during the approximately 11-year solar cycle. For several decades now, the maximum number of sunspots seen in a cycle has been declining.
The last time sunspots disappeared altogether was during the so-called Maunder Minimum, a 70-year cool period in the 17th and 18th centuries forming part of the Little Ice Age, and illustrated in the next figure showing the sunspot number over time. The Maunder Minimum from approximately 1645 to 1710 was the most recent occurrence of what are known as grand solar minima, or periods of very low solar activity, that recur every 350 to 400 years. So we’re due for another minimum.
Northumbria University’s Valentina Zharkova, a researcher who’s published several papers on sunspots and grand solar minima, has linked the minima to a drastic falloff in the sun’s internal magnetic field. The roughly 70% downswing in magnetic field from its average value is part of a 350- to 400-year cycle arising from regular variations in behavior of the very hot plasma powering our sun.
In between grand solar minima come grand solar maxima, when the magnetic field and number of sunspots reach their highest values. The most recent (“modern”) grand solar maximum, even though slightly lopsided, is represented by the blue peaks in the figure above. The figure below shows Zharkova’s calculated magnitude of the magnetic field from 1975 to 2040, which is seen to diminish as the minimum approaches.
Her calculations predict that the upcoming grand solar minimum will last from 2020 to 2053, with global temperatures dropping by up to 1.0 degrees Celsius (1.8 degrees Fahrenheit) in the late 2030s. That’s as much as the world has warmed since preindustrial times, and only 0.4 degrees Celsius (0.7 degrees Fahrenheit) above the frigid temperatures recorded in 1710 at the end of the Maunder Minimum.
The Maunder Minimum was unquestionably chilly: alpine glaciers in Europe encroached on farmland; the Netherlands’ canals froze every winter; and frost fairs on the UK’s frozen Thames River became a common sight. Solar scientists have calculated that the sun’s heat and light output, a quantity known as the total solar irradiance, decreased by 0.22% during the Maunder minimum, which is about four times its normal rise or fall over an 11-year cycle.
Other solar researchers have also predicted an imminent grand solar minimum, but for different reasons. One of the earliest predictions was by German astronomer and scholar, Theodor Landscheidt, in 2003. Landscheidt predicted a protracted cold period centered on the year 2030, based on his observations of an 87-year solar cycle known as a Gleissberg cycle, which has been linked to regional climate fluctuations such as flooding of the Nile River in Africa.
A more recent prediction, based on a longer 210-year solar cycle, is that of Russian astrophysicist Habibullo Abdussamatov. He projects a more extended period of global cooling than either Zharkova or Landscheidt, lasting as long as 65 years, with the coldest interval around 2043.
