Yup. As a college undergrad geography major I specialized in glaciation and taught a class in geomorphology. We used to joke about glaciers being sighted heading south on Highway 51 in central WI.

I think most of that was recognition that glacial cycles from the Pleistocene epoch could potentially be extrapolated to imply we're about due for another cycle. Interestingly, the warm periods between glacial advances were notable for their increased CO2 content in atmosphere --although our current level is way off the chart of those peaks.

(Personally I was always fascinated by the huge ice-marginal and meltwater lakes that dominated the warm periods. Evidence of those lakes can be seen throughout the upper midwest. Very cool to observe during long bike rides through Wisconsin.)
