The argument advanced here is that, counter-intuitively, warming climate triggers an ice age, because open Arctic waters feed the glaciers through increased snowfall. So it was climate cooling and the freezing of the Arctic that ended the Ice Age.
Close, but not quite. It's not "warming climate", but warm water flowing freely into the open Arctic Ocean that they say causes glaciation... the over-all climate still has to be cold enough for that moisture to eventually fall out of the atmosphere as snow in order for the glaciers to start growing.
Not clear they considered the warming ocean as separate from warming climate.
“The rate at which our weather has been warming in recent years could be temporarily slowed down,” they told me. “We don’t know the exact rate at which the sea is now rising. We need long-term world-wide evidence which the International Geophysical Year may give us to assess accurately the changes that seem to be taking place in the ocean and the ice.”
For snow to stop forming at higher latitudes the climate would have to heat up quite a bit.
