Because earth’s magnetosphere is weakening significantly.
Why Will This Solar Minimum Be Different?
The little ice-age patterns are repeats of historical weather/climate over thousands of years, if not many, many thousands of years when the sun’s electromagnetic field weakened.
Unique, at least compared to the most recent Minimums, the Maunder and Dalton, is that the earth’s magnetosphere is also weakening significantly which may be a precursor to a magnetic pole reversal.
Cosmic rays are exploding, inducing increased cloud nucleation leading to greater rains.
Also, the sun and earth magnetic fields are the drivers of the shifting wind patterns of our stratosphere.
The answer is there, and many, many scientists have been forecasting exactly what is unfolding and it ain’t from the Global Warming Fraud–which is, in my opinion, a globalist elite crime against humanity.
