Nature Geoscience published Goldblatt et.al. on July 28 2013, i.e. *Low simulated radiation limit for runaway greenhouse climates<http://www.nature.com/ngeo/journal/v6/n8/full/ngeo1892.html> *
The study finds an uninhabitable planet is a risk, although the last statement in the abstract contains the phrase "anthropogenic emssions are probably insufficient". Some quotes from Goldblatt are in an article in Sci-Am online, eg this one: "our new calculations show that a water vapor-rich atmosphere absorbs more sunlight and lets out less heat than previously thought, enough to put the Earth into a runaway from which there would be no return".
