How Hot Can the Earth Get?
Geologists using the bubbles in 270-million-year-old salt deposits from Kansas have estimated that they formed at temperatures of up to 74 C, or 165 F. There is some question as to how the temperature of a shallow brine pool relates to the air temperature, but the authors of this paper say they should be close. If so, wow. The earth can get really hot.
