claim: 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.
evidence: This is the "likely" range (greater than 66% probability), based on the expert judgement of the IPCC's authors.
