“…Following principles established by Shackleton (1977), Raymo et al (1997) characterized the Pacific and North Atlantic anomalies as a 600-kyr perturbation beginning $1000 ka induced by the transfer of 12 C-enriched terrestrial carbon. We believe the data are more consistent, however, with an event corresponding to isotope stages 24, 23, and 22.…”

“…The largest benthic  13 C excursion of the last 5 million years occurred during MIS 24-22, and is argued to reflect an enhanced contribution of southern-sourced waters to the deep Atlantic from 0.9 Ma and/or decreased export of NADW (Elderfield et al, 2012;Raymo et al, 1997).…”

This change in periodicity and amplitude cannot be explained by a change in 'external' astronomical forcing. Here, we review and integrate published records of sea-surface temperatures (SSTs) to assess whether a common global expression of the MPT in the surface ocean can be recognized, and examine our findings in light of mechanisms proposed to explain climate system reorganization across the MPT. Weshow that glacial-interglacial variability in SSTs is superimposed upon a longer-term cooling trend in oceanographic systems spanning the low-to high-latitudes. Regional Alongside the long-term SST cooling trends, quasi-100 ka cycles begin to emerge in both the SST and  18 O records at 1.2 Ma, and become dominant with the expansion of the ice-sheets at 0.9 Ma. We show that the intensified glacial-stage cooling is accompanied by...

“…Hence the cooling trend through the EMPT could have been driven by the observed reduced concentration of greenhouse gases in the atmosphere. This secular decline in the concentration of CO 2 in the atmosphere could have brought the global climate to a threshold, allowing it to respond nonlinearly to orbital forcing thereafter (Mudelsee and Stattegger 1997;Mudelsee and Schultz 1997;Raymo et al 1997;Berger et al 1999). Saltzman (2001) takes this further and proposes that in crossing this threshold ('bifurcation') an internal instability arises in the global carbon cycle that leads to the activation of an internal 100 kyr oscillator.…”

“…It has been suggested that long term cooling through the Cenozoic instigated a threshold, which allowed the ice sheets to become large enough to ignore the 41 kyr orbital forcing and to survive between 80 and 100 ka (Abe-Ouchi 1996; Raymo et al 1997). In one version of this, Gildor & Tziperman (2000) and Tziperman & Gildor (2003) suggest that long term cooling of the deep ocean during the Pleistocene alters the relationship between atmospheric temperature and accumulation rates of snow on continental ice sheets and the growth of sea ice.…”
