Another indicator of the current state of the sun.
June 26, 2023: There was no geomagnetic storm on June 22nd. Nevertheless, the sky turned green over rural Colorado. Aaron Watson photographed the dramatic display from the West Elk Mountains:
“I woke up around midnight to crystal clear skies,” says Watson. “I noticed some wispy rays and, at first, I thought maybe it was noctilucent clouds. Upon closer inspection there was an intense green glow rippling across the entire sky.”
Although this looks a lot like aurora borealis, it is something completely different: airglow. Cameras with nighttime exposure settings can pick up the faint emission from anywhere on Earth even when geomagnetic activity is low. All that’s required is a very dark sky.
“Airglow is produced by photochemistry in Earth’s upper atmosphere,” says space scientist Scott Bailey of Virginia Tech. “And it is very interesting photochemistry.”
He explains: There is a layer of air about 95 km above Earth’s…

I like all this my Dear Oldbrew and the inference for a decent beer – I’m with you there too, but rather than teasing out these long, though effective objections to the Anthropogenic theory of Global Warming (AGW), why not kill it off – dead – in the simplest way as follows.
The AGW insists that the Greenhouse Effect (GE) is dangerously accelerated by our CO2 emissions and we’re all going to die unless we obey our rulers.
The thermal potency of the GE depends on the conclusion that the Atmospheric Thermal Enhancement (ATE) of 33C can have no other explanation than the GE.
If pressure was lower the Atmosphere would be larger but with the same thermal energy being fed in from the surface.
This means that the thermal energy per unit volume – and therefore the temperature would be lower.
Pressure comes from the weight of the air and that is determined by the particular force of Gravity.
This forces the conclusion that Gravity, not the GE, is responsible for the ATE. Sic transit AGW.
Excuse me for repeating this argument, but the penny has not dropped – to my dismay.
If you would be kind enough to ponder you should see that it is absolutely true.
A child could embarrass a physics teacher with this, let alone a grown up expose a grandee of the AGW.
If upon further consideration you still have an objection to this argument please set it down and allow me to come back if not convinced.

Sunspot activity has increased dramatically in early 2023, with sunspot numbers far exceeding NASA’s predictions each month — though nothing as big as Carrington’s sunspots have been seen yet. Still, the profusion of sunspots and other solar weather suggests that the next solar maximum will arrive sooner and stronger than NASA previously predicted.

GIANT SUNSPOT ALERT: When the week began, sunspot AR3354 didn’t exist. Now it is 10 times wider than Earth and still growing. The sunspot burst into view on June 27th.

ANOTHER OUTBURST OF GREEN AIRGLOW: It just happened again. For the second time in as many weeks, Aaron Watson photographed an outburst of bright green airglow over the West Elk Mountains of Colorado.

Solar Max is boosting this process. Right now, the active sun is heating Earth’s upper atmosphere, increasing the rate of O vs. O2 collisions. Brighter-than-normal airglow is the result.
