Thanks for pointing out this terminological issue. I'm going to keep calling glaciations "ice ages," just because that's how they were labeled to the public in the 1970s, viz. the title of Emiliani's 1978 paper The cause of the ice ages, or, of course "The Weather Conspiracy: The Coming of the New Ice Age." :)
