Well, that's two different stories entirely, depending on whether those are degrees Fahrenheit or degrees Centigrade. Before I take my vacation there, I would like to know whether the ambient temperature is high enough to denature my proteins.
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.
Are you sure about that? I know that some extremophiles can survive temperatures in excess of 100 degrees C, but they're all single-celled creatures. I don't think complicated organisms can survive temperatures at which water boils.
EDIT: The Earth was anywhere from 2 -- 8 degrees C warmer when the dinosaurs were around than it is today. But that's still very far from boiling. http://en.wikipedia.org/wiki/File:All_palaeotemps.png
