By definition,
science is never 'settled', unless you are a
Technocrat who cannot be wrong.
Based on
studies of
the Sun, which is the biggest determinant
in earth's weather, we are headed toward global
cooling, not warming.
How will
Al
Gore, et. al, re-frame this narrative?

Recent research by Professor Valentina Zharkova (Northumbria
University) and colleagues has shed new light on the inner workings
of the Sun.
If correct, this new discovery means
that future solar cycles and variations in the Sun's activity can be
predicted more accurately.
The research suggests that the next three solar cycles will see
solar activity reduce significantly into the middle of the century,
producing conditions similar to those last seen in the 1600s -
during
the Maunder Minimum.
This may have implications for
temperatures here on Earth.
Future solar cycles will serve as a test
of the astrophysicists' work, but some climate scientists have not
welcomed the research and even tried to suppress the new findings.
New Solar
Research Raises Climate Questions, Triggers Attacks
To most of us the sun seems unchanging. But if you observe its
surface, it is seething with vast explosions and ejections.
This activity has its origin in intense
magnetic fields generated by swirling currents in the sun's outer
layer - scientists call it the
solar dynamo. It produces the
well-known 11-year solar cycle which can be seen as sunspots come
and go on the sun's surface.
But models of the solar dynamo have only been partially successful
in predicting the solar cycle - and that might be because a vital
component is missing.
After studying full-disc images of the sun's magnetic field,
Professor Valentina Zharkova of Northumbria University and
colleagues, discovered that the sun's dynamo is actually made of two
components - coming from different depths inside the sun.
The interaction between these two magnetic waves either amplifies
solar activity or damps it down. Professor Zharkova's observations
suggest we are due for a prolonged period of low solar activity.
Professor Valentina Zharkova:
We will see it from 2020 to 2053,
when the three next cycles will be very reduced magnetic field
of the sun.
Basically what happens is these two
waves, they separate into the opposite hemispheres and they will
not be interacting with each other, which means that resulting
magnetic field will drop dramatically nearly to zero.
And this
will be a similar conditions like in Maunder Minimum.
What will happen to the Earth remains to be seen and predicted
because nobody has developed any program or any models of
terrestrial response - they are based on this period when the
sun has maximum activity - when the sun has these nice
fluctuations, and its magnetic field [is] very strong.
But we're approaching to the stage
when the magnetic field of the sun is going to be very, very
small.
She suggests it could be a repeat of the
so-called Maunder Minimum - a period in the 17th
century with little solar activity that may have influenced a
cooling on Earth.
Whatever we do to the planet, if
everything is done only by the sun, then the temperature should
drop similar like it was in the Maunder Minimum.
At least in the Northern hemisphere,
where this temperature is well protocoled and written. We didn't
have many measurements in the Southern hemisphere, we don't know
what will happen with that, but in the Northern hemisphere, we
know it's very well protocoled.
The rivers are frozen. There are
winters and no summers, and so on.
So we only hope because these Maunder Minimun will be shorter,
the Maunder Minimum of the 17th century was
about 65 years, the Maunder Minimum which we expect will be
lasting not longer than 30-35 years.
Of course things are not the same as
they were in the 17th century - we have a lot more
greenhouse gas in the atmosphere. And it will be interesting to see
how the terrestrial and the solar influences play out.
This is promising research - a new insight into our sun with
predictions as to its future behavior, yet Professor Zharkova
relates than some climatologists resented her discovery.
Professor Valentina Zharkova:
Some of them were welcoming and
discussing.
But some of them were quite - I
would say - pushy. They were trying to actually silence us. Some
of them contacted the Royal Astronomical Society, demanding,
behind our back, that they withdraw our press release.
The Royal Astronomical Society
replied to them and CCed to us and said,
'Look, this is the work by the
scientists who we support, please discuss this with them.'
We had about 8 or 10 exchanges by
email, when I tried to prove my point, and I'm saying, I'm
willing to look at what you do, I'm willing to see how our
results we produced and what the sun has explained to us.
So how this is transformed into
climate we do not produce; we can only assume it should be. So
we're happy to work with you, and add to your data our results.
So don't take the sunspots which you get, we can give you our
curve. Work with our curve.
So they didn't want to.
Professor Zharkova's work may have
significantly improved our ability to forecast solar activity.
If we do enter a new Maunder Minimum,
then we are bound to discover new things about our sun and its
influences on our climate.
