I recall a few years ago a what seemed to be ground-breaking white paper from I think a Russian scientist, who argued (and convincingly) that there are two cycles at work, one deep in the Sun, the other shallow. The co-incidence of these two cycles both being at maximum, or both being at minimum, explaining the extremes of solar activity.

That sounds like Gnevishev, M. N.; Ohl, A. I. (1948). "On the 22-year cycle of solar activity" which first appeared in the Russian journal Astronomicheskii Zhurnal 76 years past.

We're in an ice age now. Humans have always lived in an Ice Age. It's called the Quaternary glaciation and it's been filled with individual glacial periods. You might want to read up on terminology. Physics, thermodynamics, informs us that the glaciers aren't coming back while the insulation in the atmosphere is high and still increasing. https://en.wikipedia.org/wiki/Quaternary_glaciation

That's pedantic. > Physics, thermodynamics, informs us that the glaciers aren't coming back while the insulation in the atmosphere is high and still increasing. Meh. The running hypothesis on the "other side" is that we're going to have a pole shift and grand solar minimum at the same time. Now, as you can see, I haven't really…

I recall back a few years reading some articles speaking about the sun entering in a Grand Solar Minimum cycle similar to the Maunder minimum, and that the result could be global cooling, etc. Not sure if there's been additional research or conjecture since then.

The theory is that we're due for another ice age and that there's going to be a pole shift. Pumping CO2 into the atmosphere would then be the best thing to do to stave off this scenario.

From what I understand, according to the best estimates this is already happening and we should have seen global cooling for a long time now if it wasn’t for greenhouse gas emissions

.. which means that the level of emissions we have right now is far, far beyond what’s necessary for avoiding global cooling.

This should be obvious if you look at best estimates of the rate of cooling/warming in the past. The warming we see now is happening much faster than anything seen before so it’s absolutely not a good thing in any conceivable way

That seems kind of extreme. While I wouldn't take this paper as proof that the sun is causing pandemics, the correlation is an interesting bit of trivia.

In what way is it interesting? And how is it trivia?

"Interesting" is subjective, but "trivia" is just information that is insignificant or of little use. Here are some other correlations you might find more interesting that are just as trivial as the one linking solar activity to pandemics:

When compared to the average person, people who prefer Miss Piggy over Kermit are more than twice as likely to have tattoos.

As the number of computer programmers in Kansas decline so do US burglary rates

Global average temperatures are correlated with the how many pirates there are

Pretty weird behavior, flagging my comment pointing out how this user's account is 30 minutes old. Very sus.
