The cosmology of the string effective action, including one-loop string threshold corrections, is analyzed for static compactifications. The stability of the minima of a general supersymmetry-breaking potential is studied in the presence of radiation. In particular, it is shown that the radiation bath makes the minima with negative cosmological constant unstable.
