Conscious Choice cover

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.

Sunspot update: December sunspot activity once again higher than predicted

The uncertainty of science: It is time to once again take a look at the state of the Sun’s on-going sunspot cycle. Below is NOAA’s January 1, 2021 monthly graph, documenting the Sun’s monthly sunspot activity and annotated by me to show previous solar cycle predictions.

The ramp up to solar maximum continued in December. Though there was a drop from the very high activity seen in November, the number of sunspots in December still far exceeded the prediction as indicated by the red curve.


December 2020 sunspot activity

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 for the previous maximum, with half the scientists predicting a very strong maximum and half predicting a weak one. The blue curve is their revised May 2009 prediction. The red curve is the new prediction, first posted by NOAA in April 2020.

The continuing activity in December reaffirms that a new solar maximum is on the way. There will be no grand minimum, at least none for the next dozen years.

What will actually happen? Your guess is as good as mine. It is also likely as good as any solar scientist’s. While the consensus of the solar scientists from NOAA, as indicated by the red curve above, calls for a relatively weak solar maximum, comparable to the weak maximum seen in 2009, their opinion is merely that. Another solar scientist, Scott McIntosh, the deputy director of the National Center for Atmospheric Research, has instead predicted that the upcoming solar maximum will not only be a strong one, it will be twice as strong as predicted by NOAA’s panel, making it one of the strongest maximums in more than a half century.

Other solar scientists had predicted we would now be entering a grand minimum, a prediction that has now turned out to be mistaken.

What must be made clear about all these predictions is that they are not based on a true understanding of what causes these solar cycles. Scientists know that sunspots are created by the Sun’s magnetic dynamo, but the fundamental reason why the dynamo goes through these cycles is not known. All these predictions are based on extrapolating past activity into the future. More important, all are also based on our limited knowledge of the Sun itself.

So, even the predictions that end up being correct really don’t tell us anything. They are mere guesses, even if educated guesses. To really understand what is going on in the Sun we will need to know a lot more about it and its magnetic dynamo, knowledge that is likely many decades away.

    Got that right. What we know from the past is that “things” happen slowly, except when there are things like impacts and volcanic eruptions. So, if we get a higher maximum, it would be expected not to be dramatic.

    This is still a good time for amateurs to buy solar scopes of the H-alpha variety.

    My eye thinks it sees the double top crowning the maximum widening for each cycle. Since 1960 when the double tops coincided to a single peak when at the highest. Widening double tops would flatten the number of sunspots over time. Almost splitting one cycle into two tops with a 4 year low in between. And it would perhaps not be physically inconceivable that solar magnetic activity is governed by multiple cycles that are out of phase with each other.

    But that’s just my eye.

    So…. The models are wrong? No way

    LocalFluff That may just be an influence by Dolly.

    However, that is something to keep an eye on!

    Have started reading “Chilling Stars”. Amazingly, the author writes in a style rather close to how the left in academia write. Many issue I take, but they are in the interpretation of sediments data and the extend of conclusions drawn. We have 400 years of sunspot data and to try to go beyond that gets into the realm of fantasy, not pure science.

    That being said, the arguments against the hockey stick are good, and Mann certainly had his credibility totally shot by his actions at the British Columbia supreme court.

    I am waiting to see how he draws conclusions to the cosmic ray and cloud theory.
