When the volcanic eruptions in the Siberian Traps occurred it triggered the Permian Extinction.
Over 80% of marine species went extinct. Over 70% of land species went extinct.
CO2 levels today are climbing to those levels.
The oil industry is funding fascism because they possess the best climate forecasters and know what's coming.
Oh, not only, they knew: https://mastodon.social/@HistoPol/109732299947236010
The only thing no-one knows absolutely nothing about regarding its climate impact are the #microplastics in the sky:

We may not have firm evidence of the consequences of environmental microplastics, but we do have ample evidence of the catastrophic effects of atmospheric particulates.
They trigger famines, little ice ages, and the end of civilizations.

I completely agree with your summary.
However, not being an environmental scientist and they stating that at this point cannot determine the direction in which this is going, I don't dare to contradict:
"But whether they would warm, or cool, the Earth is unknown...
These plastics are incredibly long lived. Theyโre breaking down, and theyโre going to be forming new microplastics for centuries. We just donโt know how big the problem is that weโve...
... committed ourselves to.โ
What really gives me headaches:
"๐The murk of #anthropogenic #aerosols in the sky has, overall, had a dramatic cooling effect since the #IndustrialRevolution (without them, *global warming would be 30 to 50 per cent greater than it is today*)๐. And they have more sway on extreme weather than greenhouse gases do: ๐a world warmed by removing aerosols would have more floods and droughts, for example, than a world warmed๐ the same...
"...amount by CO2."
So, in fact, without the offsetting effect of aerosols, we could already be competing with #Dune to be the new habitat for #sandworms.
If airborne microplastics were to solve our #GlobalWarming problems in the same way, this would just be an irony of fate, undeservedly so, I must say. ;)

I tend to distrust most speculative narratives about technological interventions in climate change.
Adding occluding microparticulates to the atmosphere isn't a likely viable option.
The best resolution to climate change is an accelerated transition to renewables and accelerated fusion research.
The globe is being deliberately hooked on an oil addiction by despots.
Ah, I know technological progress has gotten us into this #ClimateCrisis and I know that tech has failed us time and again (and I am not talking about bluescreens;)), but I am, at heart, an optimist having read too much scify in when I was younger.
I really do get your point.
In this context, however, I was not talking about a consciously developed remedy, but a side effect, as with aerosols. If that sentence is true, then we are SO lucky,..
...b/c otherwise we'd be very close to a Dune climate in most places.
Some months back, I posted a longer thread on the #BorgSite about a meta study of climate change. I like the resulting scenario technique b/c
a) it got Royal Dutch Shell very successfully out of the 1970's oil crisis and
b) you get an excellent feeling about the data as a whole (as "Data..." is your cup of tea, you will know what I am talking about)...

...Anyway, without any major, scalable breakthrough (or beneficial side effect as with aerosols), we are so thoroughly screwed.
I agree with your suggested solutions 100%. However, they will not be enough to avoid the breakdown of civilization in some regions due to climate-induced mass migrations of whole nations.
In the past, all major civilizations failed to adjust to mega-draughts:...

"the first one started some 5,000 years ago when the unification of Upper and #LowerEgypt occurred and the Uruk Kingdom in modern Iraq collapsed.
The second event, some 3,000 years ago, took place in the eastern Mediterranean and is associated with the fall of the #Ugarit Kingdom and famines in the #Babylonian and #Syrian Kingdoms."
Back then, there were not many people on the planet.
I think, green energy by itself will not solve our problems...

...I do think, though, that we have part of the solution in the area of another agricultural revolution: a combination of the nascent tech of agrivoltaics and the ancient Waru Waru technique (see my pinned thread). Other than that, we need gigantic cisterns, if we cannot use aquifers, as in many regions in California.
Apart from that, we need to consume a lot less meat and we will have to build cities under the sea and greatly expand ocean farming...

This list is not complete, though.

Ancient pollen and charcoal preserved in deeply buried sediments in Egypt's Nile Delta document the region's ancient droughts and fires, including a huge drought 4,200 years ago associated with the demise of Egypt's Old Kingdom, the era known as the pyramid-building time.
