It's the total CO2 amount in atmosphere that determines radiative forcing.
The IPCC summarized the current scientific consensus about radiative forcing changes as follows: "Human-caused radiative forcing of 2.72 W/m2 in 2019 relative to 1750 has warmed the climate system. This warming is mainly due to increased GHG concentrations, partly reduced by cooling due to increased aerosol concentrations"
All high-income countries already trend down in emissions.
Global emissions are rising because poorer countries that were basically almost "no emission"/capita in the past are still catching up (but that catch-up is less steep than in the past because green energy is available from the get-go).
Conclusions would be: Emission reductions in rich countries need to be aaccelerated, and helping poor countries peak at a lower level would probably be prudent (but good luck selling such policies to alt-right voters).
"Renewable are not helping" is not a sensible conclusion.
IVF, gamete donation, surrogacy, gay families, various experiments with human embryos or artificial wombs, much or all of this is banned in many countries of the world mostly due to the "ick" factor. The smarter opponents tend to decorate their objections in the "we must be very, very careful" cloak, but if you dig deeper, you will find that it is indeed just a cloak in many cases and that the underlying root cause is "ick, this is against nature", and "really careful" means "erect impossibly high barriers by law".
This even isn't subject to polarization and seems to be shared across the political board.
Where I live, the religious population is under 10 per cent, but complete atheists will argue like this as well.
I suspect the "ick" factor is simply inherent here. Kids provoke instinctive protective/emotional reactions in a way that other phenomena don't.
For example, it is quite obvious that Trump faces a lot more popular backlash due to his suspected connections with Epstein than over his actual threats to Denmark/Greenland and war with Iran.
