  It has been shown that the high-temperature limit of perturbative thermal QCD
is easily obtained from the Boltzmann transport equation for `classical'
coloured particles. We generalize this treatment to curved space-time. We are
thus able to construct the effective stress-energy tensor. We give a
construction for an effective action. As an example of the convenience of the
Boltzmann method, we derive the high-temperature 3-graviton function. We
discuss the static case.
