Abstract
Conventionally, the two-dimensional anti-de Sitter black hole in the Jackiw-Teitelboim model has been shown to be thermally hot; however, it raises a question of "where is the observer to measure the temperature?", asymptotically at infinity or in a finite region outside the horizon? In connection with this issue, the new local temperature is shown to vanish and to respect the equivalence principle everywhere as long as a consistent Stefan-Boltzmann law is required. Consequently, it turns out that the two-dimensional anti-de Sitter black hole must be cold.
