Inconvenient: New paper finds the last interglacial was warmer than today – not simulated by climate models

[Reposted from the Hockey Schtick] A new paper published in Climate of the Past compares temperature reconstructions of the last interglacial period [131,000-114,000 years ago] to climate model simulations and finds climate models significantly underestimated global temperatures of the last interglacial by ~0.67C on an annual basis and by ~1.1C during the warmest month. This…
