Magnetic Reversal of the Sun is underway

The sun undergoes cyclic magnetic reversals - the positive polarity [green] becomes reversed with the negative polarity [purple] over time
The process occurs at around 11 year intervals, marking the midway point in a solar sunspot cycle,called solar max.
Solar cycles are also of around 11 years duration.
NASA says
"The domain of the sun's magnetic influence (also known as the 'heliosphere') extends billions of kilometers beyond Pluto. 
Changes to the field's polarity ripple all the way out to the Voyager probes, on the doorstep of interstellar space."

The sun functions on one level as a magnetic dynamo. The reversal sees the field strength drop to zero then each polarity reformulates in the alternate value.
The Earth responds similarly to its own internal dynamo, but reversals occur in a vastly longer cycle - over hundreds of thousands of years. Most recently the magnetic field strength of Earth has been noted to be in decline since 1840.
With space science still being in relative infancy lacking a substantial body of historical references, much is to be discovered regarding the impacts of solar induced spaceweather impacting Earth & our climate, especially the issue of weather extremes.

The exaggerated undulations of the solar current sheet during field reversal bring to mind the distortions of the Earth's atmospheric jet streams.
Are they related events?
