Sunspot update March 2019: An upcoming Grand Minimum?
Even though we are now deep into the beginning of what might become the first grand minimum in sunspot activity since the invention of the telescope, that does not mean the Sun has as yet stopped producing sunspots. Yesterday NOAA released its the monthly update of its tracking of the solar cycle, adding sunspot activity for March 2019 to its graph. Below is that graph, annotated by me to give it some context.
It shows the Sun with a slight burst in activity in March, suggesting that though we are now in the solar minimum that minimum still has the ability to produce sunspots.
At the same time, for me to say that we might be heading to a grand minimum, a time period lasting many decades where no sunspots are visible and the sunspot cycle essentially ceases, is not click bait or hyperbole. It is instead based on what I now think the solar science community is thinking, based on this very graph.
The graph above has been modified to show the predictions of the solar science community for the previous solar maximum. The green curves show the community’s two original predictions from April 2007, with half the scientists predicting a very strong maximum and half predicting a weak one. The red curve is their revised May 2009 prediction, extended in November 2018 four years into the future.
For past half dozen or so cycles the solar science community had issued its prediction for the upcoming solar maximum at about this stage in the overall cycle, during the final ramp down to minimum when it was clear that the Sun had entered that minimum.
This cycle’s prediction however has not yet happened, and in fact appears to be late. In fact, the extension of the May 2009 red curve that was made in November 2018 might very well be the only prediction we see. That extension is shown by the differences between the green 2007 prediction and the red 2009 prediction in the graph. Before November 2018 both curves ended at the same place, the end of 2018.
The extension of that red curve is important. As I noted in my December 2018 sunspot update,
If you look at that curve it drops to zero and then flatlines for the entire year of 2022.
If this is what the solar science community now expects for this upcoming minimum, it means that community is now expecting a record-breaking minimum, lasting far longer than any previous minimum, two to three years at least. It also means that they have not dismissed the possibility that the Sun is about to enter a Grand Minimum, where no significant sunspot activity is seen for literally decades.
At the time I wrote that, I fully expected a new prediction for the next cycle to be issued soon. Half a year later no such prediction has been made, and I now think this has not yet happened because the solar science community is sincerely unsure what is going to happen. Though some scientists have stated publicly their belief that this upcoming minimum will either be significantly deep, or part of a Grand Minimum, others have predicted that the next maximum will be stronger than the last, and will start this very year.
Because of these disagreements and the large uncertainties they now face, I think that rather than commit to a prediction that is likely to turn out badly wrong, they have decided to wait a bit until they have a better feel for what is happening.
The extension to the red curve above however reveals a great deal about the overall sense of that solar science community. While they do not yet wish to make a public splash announcing a new prediction, the bulk of that community appears to favor a very very long and weak minimum. That red curve predicts a minimum that is at least twice as long as any previously recorded minimum, with no indication when that minimum will end.
In other words, solar scientists are now seriously considering the possibility that we are at the start of a Grand Minimum.
The consequences of this possibility will be profound. First, it will afford scientists a golden opportunity to study the Sun as it behaves in a manner unprecedented since the advent of the space age. They now have the right tools to conduct this research, and what they will learn will hopefully help explain why a star like the Sun behaves as it does.
Second, and as important, experiencing a grand minimum will finally help confirm the Sun’s influence on the climate. Past data strongly suggests a global cooling of the climate during past grand minimums, followed by warming during times of high sunspot activity. This data however is somewhat uncertain. If the climate cools during a new grand minimum, as many scientists predict and as much recent data appears to confirm, this will help clarify this fact.
More importantly , it will also force the climate science community to stop focusing solely on atmospheric carbon dioxide as the only factor influencing the Earth’s climate temperature. In recent years, for numerous political reasons, they have become obsessed with carbon dioxide to the exclusion of all else, to a point that some are even tampering with data to make it fit their theories.
Yet, carbon dioxide remains a trace gas in the atmosphere, despite its increase in recent years. In fact, of all the players that produce global warming it is a minor player. By far water in the atmosphere does almost all the work, and if it wasn’t there the climate would be ten to twenty degrees cooler.
Every single one of the global warming models admit this. Those models don’t call for the increased CO2 to directly warm the atmosphere. Instead, they claim that it will cause “feedback” with the atmosphere’s water, causing it to act to warm the climate.
None of these models have so far worked. All have failed to predict the climate’s fluctuations in the past two decades. The differences so far have not been enough however to force climate scientists to rethink their theories.
Should a grand minimum happen and be accompanied by a significant cooling, however, it will shatter these models entirely, and it will expose the data tampering for all to see. This in turn will hopefully result in a house-cleaning and shake-up within that climate science community, resulting in a refreshing new look at the Earth’s climate, less influenced by the politics that have been warping it.
Thus, a grand minimum will not only teach us a lot about the Sun and the climate. It might very well allow for a new renaissance within the scientific community, forcing out the religious believers in human-caused global warming who for the past three decades have squelched all debate.
Instead, a grand minimum will allow the real scientists, open to the actual data and not shackled to their pet theories, to shine, to put them in a position to once again run the show.
UPDATE: one of my readers today pointed me to this announcement from several days ago on April 5, 2019, in which a prediction for the next solar cycle was announced.
Solar Cycle 25 Prediction Panel experts said Solar Cycle 25 may have a slow start, but is anticipated to peak with solar maximum occurring between 2023 and 2026, and a sunspot range of 95 to 130. This is well below the average number of sunspots, which typically ranges from 140 to 220 sunspots per solar cycle. The panel has high confidence that the coming cycle should break the trend of weakening solar activity seen over the past four cycles.
“We expect Solar Cycle 25 will be very similar to Cycle 24: another fairly weak cycle, preceded by a long, deep minimum,” said panel co-chair Lisa Upton, Ph.D., solar physicist with Space Systems Research Corp. “The expectation that Cycle 25 will be comparable in size to Cycle 24 means that the steady decline in solar cycle amplitude, seen from cycles 21-24, has come to an end and that there is no indication that we are currently approaching a Maunder-type minimum in solar activity.” [emphasis mine]
According to this announcement, my guess above that some in the solar science community think a grand minimum is coming is incorrect. I will have to disagree. That I missed this announcement (even though I try to keep a close eye on what happens in this field) and that it was accompanied by no major press release, suggests that the panel does not have the full support of that community. Moreover, that they are delaying the release of their official prediction curve until later this year suggests that I am right when I say they wish to wait a bit before announcing any firm prediction.
Finally, the highlighted sentence above reveals a strong dishonest bias in this panel. The previous four cycles had not shown a weakening trend. If anything the three previous cycles, prior to the most recent weak one, had shown an increase in activity, illustrated by the high 2007 prediction. Many solar scientists at the time thought that rising trend was going to continue.
I suspect there remains considerable disagreement among solar scientists about what is going to happen, and like the field of climate science this announcement is merely the opinions of some in that community taking advantage of government largess to push their perspective.

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.
“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.

This article from the 5th implies that the forecast has happened, and they are not calling for any kind of grand minimum:
David: I try to keep a close watch on this stuff, and missed this entirely. I will update the post to note it.
–“Those models don’t call for the increased CO2 to directly warm the atmosphere”.–
Doubling CO2 does effectively inject ~3.7 watts/meter^2 into the troposphere per doubling, and the world would be a desperately colder place without the “trace” CO2 we now enjoy (even if the water vapor warming remained the same). However a doubling of CO2 would increase the average earth temp by only about 1 degree C (not “alarming”) EXCEPT for the very large water vapor and cloud reflection positive feedbacks that the modelers CLAIM.

Under current atmospheric conditions, only minor fluctuations in CO2 can happen no matter how much carbon burning we do. The earth’s atmosphere is one giant buffer. The trend that has been “seen”, may only be the natural fluctuations. Consider the ozone holes! They must be there due to the mechanisms for ozone formation in the upper atmosphere. No one had historical data on ozone concentrations so ALL observations are tainted with knee jerk reactions! IMHO
The wait and see is the best model I have seen. Empirical data is far better than predictive data.
Part of me hopes for a grand minimum, for the reasons Mr. Z outlines above. But another part of me wants no part of even a mild version of another Little Ice Age.
In the big picture, we’re due for an ice age pretty soon, and the results will be gar more catastrophic than even the wildest exaggerations of the man made climate change cult.
And that is the difference between Solar Scientists and Climate “Scientists”.
The Solar Scientists are willing to admit they may be wrong.
This in turn will hopefully result in a house-cleaning and shake-up within that climate science community, resulting in a refreshing new look at the Earth’s climate, less influenced by the politics that have been warping it.
Depends on how the federal research boodle is distributed. More politics.
Mr. Campbell – the solar scientists no longer think they can influence the sun’s behavior. It was not always so – there was a group of solar scientists at Tenochtitlan who believed the sun would respond to human sacrifice. The climate scientists of today are their heirs.
There is a contributor on Watts Up With That named Dr Leif Svalgaard he is a solar physicist and correctly predicted the last cycle.
I haven’t seen his prediction for the coming cycle yet…
“I haven’t seen his prediction for the coming cycle yet…”
According to this Russian group this next minimum will last around 30 years
Here is the paper:
Their model is very good and has been updated since this. It matches past cycles and so far has been pretty accurate on predicting the future cycles.
The model that is advanced by Valentina Zharkova predicts a period of cooling that starts about 2022. So we don’t need to wait long to see if she is right or not.

I believe that the Aztecs had some rather extreme methods to impact the solar cycle. Please to not give ideas to the Warmists.
“Doubling CO2 does effectively inject ~3.7 watts/meter^2 into the troposphere per doubling, ”
If I may:
The doubling of CO2 itself calls for 1.1 wm^2 – at a doubling. From about 275ppm to 550ppm.
Water accounts for the rest of that equation. Or there abouts. In fact, the older GISS-E FORTRAN file (Hansen/Schmidt) I have called for 3.58 wm^2 IIRC – the x3 multiplier for water is mixed into the equation.
When the IPCC says 1.6 W/m2 is from human action, they are including the water element.
It is just ‘rolled in’ even though at the 300 mbar range the water vapor is decreasing.

Donald Campbell wrote: “And that is the difference between Solar Scientists and Climate ‘Scientists’. The Solar Scientists are willing to admit they may be wrong.”
I worked in a solar astrophysics department, in the 1990s. An example of admitting they were wrong is that a popular hypothesis, back then, as to why the corona is hotter than the sun’s surface has since been proved insufficient to heat the corona enough to explain this phenomenon. Solar astrophysicists have moved on to other ideas to explain it.
For climate scientists, they still have yet to update their models in order to account for the past two decades of steady temperature. Instead, they prefer to update the data so as to match the model. This kind of action is the very definition of fudging data.
WORD ORIGIN AND HISTORY FOR FUDGE:
“The love of [the] theory is the root of all evil.” — William Briggs?
What you say about CO2 is certainly incorrect (if I understand you correctly). The Mauna Loa CO2 record is clear.
In any case, you may be interested in Dr. Spencers recent Blog article on a simple CO2 model.
It suggests that the natural limit for CO2 concentration is 500 ppm, assuming the RATE of CO2 emissions stays constant at current levels. A stunning conclusion! If true then we need not worry much about CO2 rates at the current level, regardless of current Model sensitivity calculations/alarmism.
You are incorrect.
The doubling of CO2 decreases the outbound radiation from the troposphere by ~3.7 W/m^2 (global average) assuming NO changes in tropospheric temperature or atmospheric composition (including water vapor)…ie it is an independent forcing component of ~3.7 W/m^2 (global average) per doubling CO2.
Water vapor is not considered to be a primary forcer in that it does not initiate global thermal loading, even though its presence in the atmosphere has the largest impact.
This may not seem to fully hold when some details are considered. When any hydrocarbon is burnt, water vapor is always a component of the exhaust. This is particularly significant in regard to commercial air travel. High altitude jet exhaust includes both water vapor and aerosols which are perfect in the formation of cirrus clouds in the cold upper troposphere along contrails. This is augmented by additional water vapor present in a supersaturated state. Such clouds impart a major greenhouse effect. Also,methane emitted there has an easy way into the stratosphere wherein it is oxidized into twice as many water molecules as that of CO2 by the abundant hydroxyl radicals there present. Water vapor in stratosphere has a greatly amplified greenhouse effect. Otherwise, not much water vapor makes it there.
From the above one could argue that it is a prime forcer. However, apart from its stratospheric presence, these effects are mostly short lived. Since its mean residency period is not much more than a week being largely controlled by condensation at dew point encounters in the troposphere, it cannot become well¬-mixed or be independently sustainable. If forcers suddenly decline, it cannot persist or continue to promote other feedbacks. Furthermore, if other forcers dip below baseline values subsequent declines in water vapor will produce a proportional negative feedback. It is powerful, but passive, sort of like when control levers on earth moving equipment are moved by the operator and the hydraulic system performs monumental tasks.
