"the Sun has entered into the modern Grand Solar Minimum (2020–2053) that will lead to a significant reduction of solar magnetic field and activity like during Maunder minimum leading to noticeable reduction of terrestrial temperature." The sun drives the climate, CO2 is a nothing burger.
My main point is that I don't think the graph of 1600 is comparable (valid?) with now.
In 1600, anyone watching for sun activity had limited tech - most of all, only able to capture the sun half of the time. Is the number from 1600 half of what would be captured today? or maybe even 1/4? (full 24 hours and both sides of the sun). And that doesn't even count the number of cloudy days when activity couldn't even be watched.
Only with the colonization and communication with the entire world would the true sun activity be measurable. When did that happen? ie, there wasn't a team of sun researchers in Europe, and another team in China just watching the sun constantly...
That said, the "proportion" of sun activity could be similar today - ie, what happens in 12 hours today could be the same proportion as 12 hours then, making the relative activity the same, but I don't think the researchers are going to cut their numbers to do a direct comparison.
Side note: in many places, the "average" temperature of the day is just the high and low added together and divided by two. This is arcane, especially with digital monitoring. Weighted temperatures could be easily used to get the average, but for the sake of "tradition" this method has not been fully implemented. The result is that the summer recorded average temperature is a bit lower and the winter average temperature is a bit higher than what is "felt".

Obviously the tech is much more improved today to get better counts. How can we know the true solar activity from 400 years ago compared to today?
