Direct observation of declining solar irradience.
Night time temps warming faster than daytime temps.
Troposphere warming rapidly as the stratosphere cools.
None of these are consistent with solar forced warming. All are consistent with greenhouse gas forced warming.
I never said anything about warming, that’s your line. I said, "I think these primary inputs to the system not staying constant would make it impossible to model climate such that the model could be an accurate predictive tool." Also, we’ve long moved onto “Climate Change”, even though all the models still predict warming.
> Solar energy is the primary input to the system, but it isn't driving warming.
You seem so sure, and that has me questioning my position. People seem to like to quote Wikipedia here, so I DDG'd for a few seconds with the !wiki thing. Here's what came up. I may need to throw some bucks in the Wikipedia fundraising kettle:
https://en.wikipedia.org/wiki/Solar_activity_and_climate
Says here after all of the prehistoric climate change hypothesized to be tied to solar output:
> The link between recent solar activity and climate has been quantified and is not a major driver of the warming that has occurred since early in the twentieth century.
Maybe you’re right! Let’s keep reading.
> Human-induced forcings are needed to reproduce the late-20th century warming.
I thought I was busted, except in the very next sentence …
> Some studies associate solar cycle-driven irradiation increases with part of twentieth century warming.
So solar cycle-driven irradiation CAN correlate with temperature change. And in fact, if you read the whole article you can see regular admissions there’s a lot we don’t understand and the sun is a contributing factor in varying temperatures.
Beyond that the warming we have is characteristic of greenhouse gas driven warming and not solar forcing.
Nighttime temps are going up faster than daytime temps. The opposite of what solar forcing would do.
The troposphere is warming rapidly while the upper reaches of the atmosphere like the stratosphere are cooling. Because greenhouse gasses are trapping heat at lower levels. Solar forcing would cause all levels of the atmosphere to warm. Not just the troposphere.
This has got to be measurement error or lies, damn lies, and statistics. Temperatures have swung so drastically over the last 130000 years, I just can't believe that's true.

If you've got tree rings from that time that say otherwise, then by all means share. I'll tell my scientists to standby and wait for your scientists' call.
It looks like a small hiccup in the middle of the warming. After the warming at the end of the younger dryas the planet was basically at the temperatures it would be for the entire 10,000 year holocene period. Which we are now above.
I do find all of the catastrophising of nature very fascinating. The switcheroo from "global warming" to "climate change" was pretty slick. The attempt to step the message up to "climate crisis" is going to be barrels of fun.
And, yes, I do feel for those people who are frustrated or living in fear by climate alarmists. "It's already too late ..." is full-on revolutionary agitprop. I can only hope people burn out on this whole thing, exhausted by it all, rather than have a psychotic break.
