I fail to see the difference. Of course, if we take into account possible space colonies it will not be extinction... Also the article speaks about "which refers specifically to climate changes that cause a planetary body's water to boil off". I don't think it is survivable.

Also runaway global warming is (relatively) easy to prevent by the means of geo-engineering.

Most of the planet being uninhabitable means that there are still part of it that are habitable.

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.
