If by "Ice Age" you mean period of glaciation - the most recent one ended ~ 11,500 years ago after starting some 120,000 years ago.
We're not currently in an "Ice Age" .. although by general expectation of this cycle we should be slowly moving into one . . . save for this recent rapid rise in C02 and atmospheric insulation increase caused by the most recent century of accelerated human activity.

Well, as noted we've rather changed the system parameters a fair bit, it's difficult to know what to expect where anymore other than a general increase in the amount of trapped energy at the lowest sea | land layers globally.
It's enough energy to eventually tip the otherwise periodically stable climate cells into all manner of not seen before new redistributions of climate activity.
Let's not play the dull game of pedantic definitions.
The GP to whom I replied referred to the ~ 21 Kyear glaciation cycles associated with humidity changes in the Sahara, I specifically asked about what they meant by "ice age" and pointed out that now other parameters have been altered (the insulative properties of the atmosphere) we can't reliably predict how specific regions will change in the future on the basis of the past.
Your own link clearly differentiaties between geological "Ice Age" (Quaternary glaciation of the past 2.5 million years) and the popular notion of "Ice Age" (glacial cycles during that time).
Hence why I carefully wrote:
> If by "Ice Age" you mean ..
Do by all means contribute to the discussion, that is so much better than just playing the game of "gotcha's" (or whatever it is you're doing in your comment above).
I’m actually asking the question — when we leave the ice age, will the Sahara turn green? Presumably, based on this paper, the sea water will rise and then yes it will get more rain.
