Regional.I watched a documentary the other day about the fall of the akkadian empire, and apparently they suspect it was due to the 4.2 kiloyear event. It turns out that within 230:ish years, nature, (without any CO2) changed dramatically which led to less rain, which led to food shortage. Estimates say that the temperature in the region dropped 1-2 degrees C, naturally in such a short time.>
Did it say the global temperature dropped that much? Or was this a regional event? Regional events of this kind are common. IIRC it is believed that the Mayans also ran into unfavourable climate change, though this is not settled. But it's doubtless settled enough for a TV show.

I would. And so would literally anybody else who spent some time reading on the subject.
