Leaving aside that we are ourselves currently in the middle of an Ice Age (it's a warmish interval at the moment), for most people the term conjures an image of vast ice sheets, and less than a century just isn't long enough for those to develop. Sea level data for previous recent periods of glaciation seem to show something like a meter drop per century, which probably isn't enough water for miles thick ice sheets anywhere yet. Dozens of meters in places maybe.
On the other hand, a century at +7 C is probably ample to melt all the existing ice, which has put those equivalent points in London under 100 meters of water on Aftershock-2.
Of course a process able to generate a global drought is probably physical nonsense, so it may not care very much about realistic water cycles on the other linked timelines either.
