Dansgaard‐Oeschger oscillations predicted in a comprehensive model of glacial climate: A “kicked” salt oscillator in the Atlantic (2014, unknown): “An alternative hypothesis involves the idea of “stochastic resonance” [Alley et al., 2001; Ganopolski and Rahmstorf, 2002] in which a small-amplitude harmonic excitation of the Atlantic meridional overturning circulation (AMOC) is amplified in the presence of noise.”
The DO-climate events are probably noise induced: statistical investigation of the claimed 1470 years cycle (2006, methodology): “Furthermore, if the periodicity is such that every now and then a periodic jump is “skipped”, as is the case in a stochastic resonance (Alley et al., 2001), this will also reduce the power in a spectral peak.”
Large‐scale instabilities of the Laurentide ice sheet simulated in a fully coupled climate‐system model (2002, background): “For example, it was shown that millennial-scale Dansgaard-Oeschger oscillations, which are triggered by random freshwater forcing, can be synchronized with a very weak periodic 1500-year forcing via a mechanism called stochastic resonance [Alley et al., 2001; Ganopolski and Rahmstorf, 2002].”
Timing of abrupt climate change: A precise clock (2003, background): “This highly precise clock points to an origin outside the Earth system; oscillatory modes within the Earth system can be expected to be far more irregular in period.”
Rapid changes of glacial climate simulated in a coupled climate model (2001, background): “The ‘waiting time’ between successive D/O events is most often around 1,500 years, or, with decreasing probability, near 3,000 or 4,500 years (ref”
Noise-Induced Phenomena in the Environmental Sciences (2011, background): “Ice-core records indicate that the waiting times between two consecutive DO episodes are clustered around 1500 yr, and – with lower probability – around 3000 and 4500 yr (Alley et al., 2001), as shown in Fig.”
The role of the thermohaline circulation in abrupt climate change (2002, background): “In Greenland ice core records, abrupt warmings exhibit a preferred waiting time of 1,500 ± 500 yr (ref”
