The variance of weather is then still the same, but the seasonal warming over this longer period is much larger, so now you get a sensible signal / noise ratio.

In some sense, the search for a theory of glacial - interglacial cycles amounts to a search for the «rectifier» which turns the modulation of the amplitude of the seasonal forcing into a rectified signal in global ice volume.
