  The near extremal Reissner-Nordstrom black holes in arbitrary dimensions ca
be modeled by the Jackiw-Teitelboim (JT) theory. The asymptotic Virasoro
symmetry of the corresponding JT model exactly reproduces, via Cardy's formula,
the deviation of the Bekenstein-Hawking entropy of the Reissner-Nordstrom black
holes from extremality. We also comment how can we extend this approach to
investigate the evaporation process.
