We discuss the gross thermodynamical properties
of brane-worlds with a focus on the Randall-Sundrum scenarios. We
argue that the Gibbons-Hawking effect and the Hawking-Page phase
transitions are both realized in these five dimensional brane world
models, and hence they may both play a role in early
universe cosmology. This could be
particularly interesting during an de-Sitter phase associated with cosmic
inflation, where thermal effects are responsible for the
