"A linear fit to the changing magnetic field produces a slope of 77
Gauss per year, and intercepts the abscissa at 2015. If the present
trend continues, this date is when sunspots will disappear from the
solar surface."
Plenty more at the url mentioned.
Time to stock up on long johns?

Oh Doom , Doom , Doom is me
Bring back the proper snow of the late 1940's
It was great for building "Proper Snowman" as a six year old

Sunspots are certainly areas of lower activity and, for radio amateurs, it
is the "gaps" between the spots which are of more interest as these lead to
higher radiation of the type which (at the right level) enhances
propagation.
I'm not sure of the effect on the earth's temperature, I suspect it is
marginal.
Being a man made global warming skeptic, I'm sure our world leaders will
have another monster bash and we will be taxed to make up for the lack of
solar activity. I blame it on the science of "heat bands" and "N-Rays".

AFAIK the Maunder Minimum is usually linked with the ~250-year Little
Ice Age, although increased volcanic activity, internal variability of
the climate system, and anthropogenic influences are also mentioned.

??? Is it not the plasma in the magnetically constrained hoops
loosing energy that cause the needed radiation .. and when the
magnetic containment fails .. results in a total release .. ie a
flare .. that has the opposite effect on propagation ?

Depends on the flare type (size), which is why I included "at the right
level".
Solar flares are classified as A, B, C, M, and X.
A & B tend to have no effect on HF Prop.
C are generally "good"- intense enough to enhance the F layers but not the D
layers. The MUF goes "up" but the LUF is (essentially) left alone.
M enhances te MUF and the LUF but may leave a "gap".
X can push the LUF beyond the MUF and you get a "blackout". Remember, we
use the "gap" between the LUF and MUF on HF.

Whilst RSGB representatives are classified as T,W,A,T,S
