Jonathan Cohler and Willie Soon present a rebuttal to assertions made by Ned Nikolov about the physical meaning of global mean surface temperature (GMST). They argue that GMST is a physically meaningless statistical construct that cannot represent the Earth's thermal state or energy content due to its basis in non-equilibrium thermodynamics. They emphasize that temperature is an intensive property and its aggregation across different systems is fundamentally flawed from both mathematical and thermodynamic perspectives.
