May be it will be highest mountains after 7000 meters, which will turn from − 50 to +30 C.
Wiki said that threshold for water runway warming is 47 C (at 10 per cent high solar luminosity) and if it reached, the temperature will reach 900 C in new stable state. https://en.wikipedia.org/wiki/Future_of_the_Earth#Loss_of_oceans
It means that very hot earth where small highlands will still be habitable - is still in unstable condition and could have much higher global warming.
