The Impact of Abrupt Climate Change around 2650 BP in NW-Europe, Evidence for Climatic Teleconnections, and a Tentative Explanation
Gee, that type of incandescent light bulbs and v8 cars did they have back then that caused that climate change? And how could it happen in that area when all the bad folks who consume so conspicuously are Americans?!?!? Andf how could they get such a radical change without Styrofoam Bug Max boxes?
It was Bush’s fault.
A cooling period in Europe would definitely have spurred the subordinate tributary tribes along the Danube to boot out the warrior elite groups ~ at just this period of time.
Galician records report that the Celts arrived in Northern Spain in this period, and moved on to Brittain about 100 years later (as things warmed up presumably).
It's all making sense now.
