There is only 1 climate-model, that I know-of, which isn't contradicted by the still-accelerating planetary heating, and it predicts planetary heating of over 5C if one doesn't include the CO2 equivalent of the methane we've added to the atmosphere, & it predicts about 9C planetary heating if we keep the CO2 & methane the same.

It's a powerlaw. Same as what actually rules lightning, flooding, hurricanes, tsunamis, quakes, climate punctuations, etc.

Notice that the world "consensus" is centered on 1.5C and 2C.

The accelerating release of methane from melting permafrost .. probably means it isn't possible for the amount of methane in the atmosphere to be reduced .. any more.

( 1ppm methane in the atmosphere has a 20-year effect about 82.5x as intense as 1ppm CO2.

I've no idea how long it actually lives in the atmosphere, though, so it may be much worse )

I don't know that Greece will be inhabitable by the end of this century.

I honestly don't know if anything in the tropics, or even near, will remain inhabitable.

It might be that only Siberia will remain inhabitable, and Antarctica.

I don't think it'll get that bad, but .. dear God is humankind ignoring reality as devoutly as it can.
