We examine the behavior of the nonlinear interactions between electromagnetic fields at high temperature. It is shown that, in general, the ln([ital T]) dependence on the temperature of the Green functions is simply related to their UV behavior at zero temperature. We argue that the effective action describing the nonlinear thermal electromagnetic interactions has a finite limit as [ital T][r arrow][infinity]. This thermal action approaches, in the long wavelength limit, the negative of the corresponding zero-temperature action.
