A 2010 paper by University College London (UCL) reported:
‘Evidence from ice-core and marine records for the last glacial period and climate models has supported this bipolar seesaw process, but the extent to which its operation is affected by climate conditions and the hydrological cycle remains unclear. This new study, published in February’s Nature Geoscience, shows that the bipolar see-saw was a feature of the penultimate glacial period, but that its operation was also modified by the background climate state.’
Now a new paper on this topic has appeared.
