Climate-heating greenhouse gases hit new high, UN reports
The concentration of climate-heating greenhouse gases has hit a record high, according to a report from the UN’s World Meteorological Organization.
The jumps in the key gases measured in 2018 were all above the average for the last decade, showing action on the climate emergency to date is having no effect in the atmosphere. The WMO said the gap between targets and reality were both “glaring and growing”.

And? So what? CO
2, Methane, and Dihydrogen Monoxide have all been much higher in the past... Try the Paleozoic Age for example, where there was a superabundance of fauna & flora.

Here's the ice ages:

Now overlay that with the CO
2 level:

"We show that the Maastrichtian atmosphere is unlikely to have contained more than about 1300 ppm by volume of CO2.This value agrees with an independently modeled value of CO2 in the Late Cretaceous atmosphere."
Infact, I answered all your queries of this post:

But you could not understand it. So you were right when you said:
"BTW: This isn't an honest discourse - this is merely point scoring."
Was that a Fraudian {sic] slip? Did the lack of honesty refer to yourself?
Notice that Earth has had ice ages during high CO
2 periods, such as the Cretacious (
4 times now!). Oh dear; doesn't fit the agenda, eh?

Fancifully embroidered shit-posting using YouTube as a reference source, how novel.
When Galaxian posts links & references, it is churlish to expect that the details are painstakingly explained. It is as if an expression for integral calculus is written, and you say,
"prove it!" It is for YOU to prove it to yourself. Not for me to throw good hours after bad, blowing your nose & wiping your bum, because you can't even grasp well presented videos.
Then, how the hell do you expect to understand a scientific thesis in a journal? So your bravado in trying to scorn Galaxian's work in simplifying things for you has backfired. Here is a science publication from Valentina Zharkova about just part of that YouTube topic. Read & be confused...Confusion would fit you well:

"....We derive two principal components (PCs) of temporal magnetic field variations over the solar cycles 21–24 from full disk magnetograms covering about 39% of data variance, with σ = 0.67. These PCs are attributed to two main magnetic waves travelling from the opposite hemispheres with close frequencies and increasing phase shift. Using symbolic regeression analysis we also derive mathematical formulae for these waves and calculate their summary curve which we show is linked to solar activity index. Extrapolation of the PCs backward for 800 years reveals the two 350-year grand cycles superimposed on 22 year-cycles with the features showing a remarkable resemblance to sunspot activity reported in the past including the Maunder and Dalton minimum...."
