the schmittner et al. study finds low probability of both very low and very high climate sensitivities, and its lower estimate (as compared to the ipcc) is based on a new temperature reconstruction of the last glacial maximum that may or may not withstand the test of time.

climate change feedback:83
this is the "likely" range (greater than 66% probability), based on the expert judgement of the ipcc's authors.
