  We study radiative parton energy loss in an expanding quark-gluon plasma with
magnetic monopoles. We find that for realistic number density of thermal
monopoles obtained in lattice simulations parton rescatterings on monopoles can
considerably enhance energy loss for plasma produced in $AA$ collisions at RHIC
and LHC energies. However, contrary to previous expectations, monopoles do not
lead to the surface dominance of energy loss.
