You are making the same mistake that "warmists" make. They look at a short, near-term, cycle and extrapolate forward. Yes, the Sun has an 11-year sunspot cycle. It also has cycles of much longer duration and while sunspots may return, there is a good possibility it won't be anytime soon. The historical trend has been 100,000 years of cold followed by 10,000 of warm.
Guess where we are in the curve.
“They look at a short, near-term, cycle and extrapolate forward.”
Indeed. But I am neither a “warmer”, nor a practicing scientist (though I have a few academic degrees from the past that might indicate that I was). Since I have no current expertise, or recent academic on such matters I must rely upon reading a lot since I am not terribly bright (truly!).
As such I’m only a very “short, near time cycle” myself. I’m probably going to make it through at least one more sun cycle. With luck, maybe two. As such, my event horizon is a bit closer in than the really neat graph you’ve provided. While it’s fascinating on a solar scale, it is of less practical interest for someone that is just “passing through”. I hope you can understand why my interest in the phenomenon is on a shorter temporal scale.
How do you suppose they came by the data for such an extended period? Certainly interesting stuff.
