LIA was certainly noticable around N Atlantic, but not globally synchronous. The CO2 drop certainly contributed to temperature drop (~0.1C), but there were also an unusual number of big volcanoes. From IPCC AR6 WG I, for example.

Bill Ruddiman, “Plows, Plagues, and Petroleum” (2005).
Then: Koch, et al(2019), 90% die-off 1500-1610, contributing to unique in last 2000 years 7-10PPM drop in CO2, due to reforestration.

Reminder of Ken Thompson’s 1984 Turing lecture, Reflections in Trusting Trust, about a1975 hack:
https://www.cs.cmu.edu/~rdriley/487/papers/Thompson_1984_ReflectionsonTrustingTrust.pdf
It’s even more relevant now given the greatly-increased layers of software used by programmers.
Tidbit: AFAIK, out group was the only one to notice this hack, which occurred a few weeks after I’d read John Brunner’s The Shockwave Rider & laughed prematurely at idea of worms with infinitely-replicating tails.

Of course, at this point, removing fluroidation is dumb ...
but strangely, some UCSF friends of mine found that among the biggest pushers of fluoridation were NOT communists, but Big Sugar... to deflect from the awful possibility of reducing tooth decay by reducing sugar intake.

@robpike
I’ve heard this business plan before.

Anyone who uses products/services based on VLSI semiconductors, especially those with ARM microprocessors (i.e., ~all smartphones) should know major contributions were made by trans folks, both Fellows of #ComputerHistoryMuseum, among many other honors.
