Glacial terminations and interGlacials reconstructions of the past climate unambiguously show that climate can shift abruptly on decadal timescales. Evidence of abrupt transitions comes from both the present Interglacial (the Holocene) and the Last Interglacial (e.g. Alley et al. 1997; Pol et al. 2014). However, there is still considerable uncertainty concerning the role of the different climate forcings in causing abrupt shifts. Constraining the sensitivity of interglacial climates to each forcing is a prerequisite for assessing the future risk of abrupt changes and the potential impacts on societies.
