The Black Death is estimated to have killed 30% to 60% of Europe’s population, reducing the world’s population from an estimated 450 million to between 350 and 375 million in 1400

Just the start of the mini-ice age that lasted from 1350 to 1750.

Caused by lack of sunspots.

for the one and only sunspot this last week as the sun rotates once in 27 days.

bottom line...prepare for another mini ice age as well as that listed above.

for the one and only sunspot this last week as the sun rotates once in 27 days.

Not only are there far fewer/smaller sunspots, the overall strength of the Sun's magnetic field has been decreasing for several decades.

It's been demonstrated in a lab that lower magnetic field => more gamma rays => more clouds.

Real science, not "computer models".
