The solar cycle
is a periodic 11-year
fluctuation in the Sun’s
magnetic field,
during which its
North & South poles
trade places.
This has an enormous
effect on the number
and size of sunspots,
the level of
solar radiation,
and the ejection
of solar material
comprised of flares
and coronal loops.
–Interesting Engineering.
Lower sunspot counts
reflect lower solar energy.
HISTORY:
Within “The Little
Ice Age” centuries
there were several
solar minimums
-- long periods with
low sunspot counts.
If solar variations
controlled the global
temperature, we
would expect the world
to get colder during
a solar minimum,
reaching the coldest
point just before
the minimum ended.
Unfortunately,
real time temperature
measurements were
not available from
many locations
to check that.
Using the Central
England real time
temperature data
only:
-- That exact pattern
did not happen.
-- Closest to
that pattrern
was the cold period
between 1650 and
the early 1690s
during a long
sunspot minimum,
known as the
Maunder Minimum.
It was named
after astronomers
Edward Maunder
and his wife Annie
Russell Maunder,
There was
a downturn
in temperatures
in Europe and
North America.
Other parts
of the world
did not keep
real time
temperature
records,
but climate proxy
studies show
the cold weather
was not confined
to only Europe and
North America.
NASA reports,
solar activity
recently dropped
to the lowest level
in 200 years.
From the official
NASA website:
The forecast
for the next
solar cycle
says it will be
the weakest of
the last 200 years.
The maximum
of this next cycle
– measured in terms
of sunspot numbers,
a standard measure
of solar activity level
– could be 30% to 50%
lower than the
most recent one.
NASA predicts
the next
solar cycle
will start in 2020,
and reach its
maximum in 2025.
NASA insists
everything
will be fine.
In the past,
low solar activity
lasting for
several decades
has usually meant
colder and snowier
than usual winters.
The effect
of just one
11-year
solar cycle
has NOT been
measurable.
HAS OUR PLANET
HAD UNUSUALLY
COLD WEATHER
RECENTLY ?
Here's what I found
in the past few weeks
-- I don't know
if this is evidence
of anything,
... maybe just
some unusual
random weather
events, typical
of most years:
ICELAND:
December 20, 2019,
brought Iceland
one of the largest
snow storms
in its history.
The so-called
“10-year storm,”
brought winds of
100 miles per hour
( 161 km/h ),
with one
weather station
reporting gusts
of up to 149 mph
( 240 km/h ),
according
to a report
by Interesting
Engineering.
EGYPT
Cairo, Egypt
turned white
at the start
of January .
After not
having snow
in 112 years.
GREECE:
Many parts of Greece
were covered in snow
in early January,
with low
temperatures
and strong frost.
The cold front
brought rain,
sleet and ice
in the east.
