Kilimanjaro had glaciers down to 3200 m (ice, average, temperatures, night)

The Wikipedia article for Mt Kilimanjaro indicates that glaciers extended down to 3200 m of elevation during the Pleistocene. Assuming that this corresponds to a daily mean of 0 degrees C at the 3200 m level (a wild assumption), this suggests an average temperature of around 21 degrees C at sea level, which is 6 degrees cooler than today. Does this sound plausible for equatorial temperatures in an Ice Age? Temperatures would likely be around 25 C day/17 C night year-round.

I think the assumption glacial line = 0°C is actually a good one for the tropics, read about that topic, I'd have to re-read. If it got drier or wetter the relation should change. The other assumption you have there is the lapse rate is 6.6°C/km. May change with humidity changes.

Thanks for the reply. It's rather difficult to find information on how glaciation could've affected the tropics, but it's a fascinating topic.
