The glacial cycle is most certainly driven by disruption of heat from the Atlantic to the Arctic and restoration of heat from the Atlantic to the Arctic. And are long lived events. So that's a yes, the exact same heat transport that led to the end of the glacial period is still driving the interglacial period.Is that a yes or a no? The normal glacial-interglacial cycle is not driven by D-O events. And as we have just demonstrated, current warming is many times faster than glacial cycle warming.
