Emilio Spedicato's idea (circa the 1990s) is that ice ages are caused by impacts on land, and ended by impacts on water; that seemed wrong immediately, but gave me a thwack on the forehead -- ice ages are caused by impacts on water, always, and they end due to the fact that the distance to the Sun doesn't change much, and basically everything thaws out. This explains the ice distribution, and permits ballparking the location of the originating impact (or impacts, in the case of doublet impacts).
