Cosmological backreaction and the future evolution of an accelerating
  universe
  We investigate the effect of backreaction due to inhomogeneities on the
evolution of the present universe within the Buchert framework. Our analysis
shows how backreaction from inhomogeneities in the presence of the cosmic event
horizon causes the current acceleration of the Universe to slow down in the
future and even lead in certain cases to the emergence of a future decelerating
epoch.
