Is it really that ambiguous given the submission title?

I'd say it's still ambiguous. Liveable for us or liveable for something?

Even on Earth we have hyperthermophiles (http://en.wikipedia.org/wiki/Hyperthermophile) which can tolerate temperatures of up to 122 celsius.

And before anyone says "water boils at 100C", that's only at Earth-ambient atmospheric pressure.
