There was an actual proposal to artificially darken the pole ice sheets. A change in albedo is one of the fastest ways to warm the earth's surface.

I also wonder if occasional burst of volcanic activity in the far north might not dump a lot of detritus on the ice sheets and produce temporary melts. Antarctica would be more vulnerable to this, because the rate of deposition of ice there is very low (very low precip) across most of the area.
