We reanalyze the velocity dispersion – surface density relation of Giant Molecular Clouds. This analysis reveals a transition from virial to super-virial velocity dispersion at a self acceleration of about 108 cm s2 . Similarly, there is a transition at an H2 number density of about 600 cm3 . Possible implications are addressed.
