Construction costs are currently skyrocketing

I am not aware of any study that can quantify the exact impact of humans.

I have the impression that you are interested in keeping it that way.

You did not understand my intention. We cannot stop climate change, but at most slow it down.

Maybe, but then only because we are too stupid and NOT because a natural climate warming is just around the corner anyway. Natural climate change is primarily driven by the Earth's orbital cycles and therefore has a frequency of tens of thousands of years. We are currently in a natural cooling phase, but on the short timescale of 100-200 years, one may also say "stable." Nevertheless, the global(!) temperature is rising at an almost unique speed (100 years compared to tens of thousands) even though no natural factors support this. So we can at most not stop what we ourselves have started. Against this background, a reference to geological and much slower natural climate change is simply meaningless. Of course, the climate has always changed purely naturally since the Earth exists. Regarding the influence of the large-scale chemical CO2 production that has taken place only in the last 150 years (geologically unique), that says: nothing.

It is a logical rule of three:

CO2 insulates the Earth's surface from space through its infrared activity, but lets sunlight pass through unhindered to provide the heating power of that surface.

More CO2 = better insulation

Better insulation with the same heating power = higher temperature

CO2 man-made = proven (where else would the combustion product go? As well as isotope ratio C12/C13/C14)

CO2 effect quantifiable (Schwarzschild equation directly derived from quantum mechanics, unfortunately not easy for laypeople to process)

Result of the logical chain: human-caused warming.

Added to this are feedbacks and tipping points. The isolated "pure" CO2 effect to be calculated therefore does not appear in reality. It will be more than that. How much more is indicated by science within an uncertainty range.

Why do you need a study for that? Possibly I can find a free one. I would rather recommend a (good) popular science book, as it offers more in less space and points to references.

Oh, how nice it would be if instead of the prices of construction timber, the prices of SUVs, easyjet tickets, and T Bonesteaks went through the roof, oh, AfD save us, hear us, the flight to Malle is in danger.

And do we know if we can still stop the tipping point? A few e-cars in Germany save us from climate collapse or a goblin in the chancellor's office?

I am at least skeptical about that. I rather believe that every innovation is blocked by communism. That will be our end, not the globally unregulatable CO2 emissions.

That’s what I meant by “half solution” = no solution: From the tipping points onward, you lose control. Will it happen like that? I think so. An opinion, not a fact or anything.

Does that mean we don’t need to do anything or try? Far from it.

Not every ban, every regulation, every felt lack of freedom is communism. No one would consider regulation if “great freedom” had performed as well as is often claimed...

Will the alternative be better? Honestly: I don’t know and don’t know anyone who does. I would take the risk because I consider the alternative to be worse.
