“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.
If we can trust the data, (derived from proxies) global temperatures have previously dropped precipitously in a short period. I have heard 6°C in twenty years.
The implications of such a decline are nothing short of cataclysmic. and could certainly alter things on a "temporal scale".
Think about this: The entire history of civilization has taken place during the current interglacial.
“How do you suppose they came by the data for such an extended period?”
For part of it they use ice-core data, and I believe lake bottom sediments as well. Various chemicals get trapped that somehow give an idea of the temperature I think?. CO2 gets trapped in the ice (bubbles?), and the dust obviously.
