Construction costs are currently skyrocketing

Humans have continuously evolved under pressure. Either through evolution or through technological revolution

That would indeed be quite a feat, because for that humans would have to adjust their body temperature within a few decades to be able to live at constant temperatures above 40°C and high humidity.

But from you, it’s usually just hot air anyway. Or am I confusing you?

Humans have always evolved under pressure. Either through evolution or through technological revolution

Evolution in this case means migration or death.

+3 degrees is almost +6 degrees inland. Aside from that, sea level rise will then approach +1m/century. This affects Hamburg just as much as NY as Bangkok as... etc.

Even the greatest optimists cannot say what an adaptation might look like that does not include population reduction.
Blessed is he who then lives in the 1st world.

It is the price of technological progress, which ironically is paid most dearly by those who benefited least from it.

A practically viable way out (not just a theoretically possible one) is not in sight. It’s about mitigation, temporal stretching, long-term plans for certain plausible cases.

We are trying the first and second. The last we ignore (for now). Because in extreme cases the conversation is always about rescue vs. total demise, to justify agenda setting.

A few current building material prices compared to 05/2022. Some items have become more expensive, but some have also become cheaper. Here are a few excerpts. The total difference for the -complete- shell construction amounts to +0.29%.

The explosion of all building materials and interest rates by 8% at last year's turn, talked up by 1-2 users, apparently did not occur....

The explosion of all building materials and interest rates by 8% at the last New Year's, talked up by 1-2 users, apparently did not happen....

The construction industry is collapsing thanks to the interest rates. Massively. You can see it at the Federal Statistical Office. Pricing power or cash flow maintenance in the future?

A builder does not buy reinforced concrete mats, but rather a shell construction or similar. And the following applies:

Prices for the construction of new residential buildings have increased by 15 percent within one year. This was reported by the Federal Statistical Office in Wiesbaden. Accordingly, for example, the shell construction work became almost 14 percent more expensive compared to February of the previous year...The Federal Ministry of Construction expects a further increase in the cost of residential construction of six percent for the current year.

A builder does not buy reinforcing steel mats, but a shell or similar. And this applies:

A builder buys a shell as you wrote - and this total became 0.29% more expensive ;)
