SOLAR CYCLE 25 UP-DATE
The comparison of Solar Cycle (SC)25 to its predecessor SC 24 currently indicates that there is little difference in activity at the same point in time after they began. Looking at the chart below, the two bottom lines, are SC 24 and 25. Several months ago, SC 25 was more active than SC 24 and that lead to the thought it would be much more active than SC24. The expert forecasts mostly said that they would be much the same. At this point, the forecasts of similarity appear to be accurate
The following chart shows the history of the recorded SCs. Sunspot numbers have only been collected for recent centuries. When a series of SCs having low numbers of sunspots occur, historically, the result is global cooling. When a series of SCs occur with high numbers of sunspots, the result seems to be warming.
Beginning in the early part of the last century, SCs were highly active, peaking with SC19. SC19 has the record for most sunspots. The SCs that followed were highly active until SC 24. This period has been called a solar maximum.
The timing of the solar maximum and the increase in atmospheric CO2 are rivals for the reason that global temperatures have risen beginning in the latter part of the last century. Perhaps they both have been complicit.
I believe that the Sun is the major factor determining global climate. The trajectory of the SC 24 and probably SC 25 would suggest a global cooling is in the offing. This should be a defining period.

Hi CB,
I clicked ‘like’ and it seems to have worked. Maybe later I will try to make a comment like this: PURE DATA, easy to see there is no opinion that is not supported by FACTS. And hopefully, anyone, scientist or not, can see how the magnitudes at the beginning of the cyclic generally predicts magnitudes which follow. When you wrote: “Several months ago, SC 25 was more active than SC 24 and that lead to the thought it would be much more active than SC24.”; it must have been with tongue in your check. For clearly the beginning magnitudes of SC24 was visibly less than that of SC23 etc. And one does not need to be an expert to see this.
Have a good day, Jerry

Jerry thanks for the comments
Well, it may not show up much but the progression of the International Sunspot Number on SC 25 went like this—from 2020 Oct to current reading, 14.6 34.5!!! 23.1 10.4 8.2 17.3 24.5 21.2. That early jump looked maybe it was a deal breaker. But with time it has settled down and is now in step with SC24 performance.
Oh, I gave you presence on the May anomaly that I published a few minutes ago.

Hi CB, I have had ‘College Physical Science 3rd Ed’ (1971) by Slabaugh (former student) and Butler (former professor) for years and never (to my memory) opened its cover to even look at its table of contents. I had bought it cheap at a book sale because Slabaugh had been a professor of chemistry at Oregon State University while I was a graduate student there.
About three days ago I opened it and read the Table of Contents. Chapter 21 Complex States of Matter pp 436 of more than 600 pages of a TEXTBOOK !!! 1. Colloids 2. Brownian Motion 3. Optical Properties of Colloids 4. Surface Energy and Adsorption 5. Surface Charges 6. Diffusion and Osmosis 7. Other Colloidal Systems 8. Summary
Chapter 21 began: “In proceeding chapters we have been concerned mostly with the molecular structure of the three states of matter. Earlier we examined the atom, with its composite electron-proton-neutron structure, as a still smaller unit of matter. From the realm of dimensions in the range of less than a few Angstroms [A] up to objects that can be seen with the naked eye there is a gap that is often neglected in an introduction to physical science. Those systems composed of particles with diameters ranging from about 20 (A) up through 5,000 (A) (0.02 microns to 5 microns) have many properties that are often in sharp contrast to the properties of single molecules or bulk samples of pure substances.”
As my thesis research I experimentally studied the diffusion of divalent cadmium and lead cations in single crystals of NaCl and KCl single crystals. And given the proposed mechanism of this diffusion, nothing seemed to be complex.
And clearly atmospheric scientists could profitable greaterly by reading this chapter. (My Opinion and no opinion that I too could have profited greatly by reading earlier editions of this textbook). The 1st Ed. was published in 1958 near the time of the 1st Sputnik.
Have a good day, I have copied this information to work it into a comment at PSI. Do not yet know where but I am sure the context for it will happen.
Have a good day, Jerry
