" The future predicted activity of the Sun has been likened to the Maunder Minimum.
This was a period when the Sun entered an especially inactive period,
producing fewer sunspots than usual.
This minimum happened at the same time that conditions in Northern America and Europe
went unusually icy and cold, a period of time known as the “little ice age.”
"Zharkova compared the Maunder Minimum with the one that her team predicted
to occur around 15 years into the future.
The next minimum will likely be a little bit shorter than the one in the 17th century,
only lasting a maximum of three solar cycles (around 30 years)."
"The conditions during this next predicted minimum will still be chilly: “It will be cold,
but it will not be this ice age when everything is freezing like in the Hollywood films,” Zharkova chuckled."
(My take : We have 15 years to prepare for routine cooler/ colder temperatures, if her analysis is accurate.
Worldwide ambient temperatures, jet stream, and climate are controlled by ocean currents and temperature which comprises 71% of the earths surface, and is based on solar gain/loss.
The oceanic bodies of water warm or cool much more gradually than air temperatures, so such change should be gradual.)
Ah, that’s what I was looking for.
Thanks.
Just colder than average temperatures.
So, 15 years will be about 2030 for cooler temperatures.
Around year 2000 it was slightly warmer temperatures.
In the 1970’s, it was cooler temperatures.
Many things are cyclical.
