The dominant mode of climate variabiity during the Quaternary/Pleistocene has been characterised by ~100,000 year oscillations between glacial- and interglacial climate states. It seems clear that these climate cycles have been paced by changes in the seasonality of solar radiation (i.e. insolation), but it is also clear that this pacing was made possible, and was amplified by strong positive feedbacks internal to the climate system. Albedo- (ice sheet) and carbon cycle (i.e. carbon dioxide) feedbacks appear to have been foremost amongst the contributing feedbacks. Despite over a century of research, it remains unclear exactly how these feedbacks were triggered and coordinated by insolation changes. Ongoing research is seeking to address just this question, and to use the ‘zoo’ of past glacial and interglacial climate states as a natural laboratory in which to investigate the context dependence of climate feedbacks, which ultimately must underpin the non-linearity that Quaternary glacial-interglacial dynamics exemplify.
