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 sensitivity:58
for constant humidity they computed a climate sensitivity of 2.3 °c per doubling of co2 (which they rounded to 2, the value most often quoted from their work, in the abstract of the paper).
