New Hypothesis

Recent advances in palaeoclimatological and meteorological research, combined with new radiocarbon data from western Anatolia and southeast Europe, lead us to formulate a new hypothesis for the temporal and spatial dispersal of Neolithic lifeways from their core areas of genesis. The new hypothesis, which we term the Abrupt Climate Change (ACC) Neolithization Model, incorporates a number of insights from modern vulnerability theory. We focus here on the Late Neolithic (Anatolian terminology), which is followed in the Balkans by the Early Neolithic (European terminology). From high-resolution 14C-case studies, we infer an initial (very rapid) west-directed movement of early farming communities out of the Central Anatolian Plateau towards the Turkish Aegean littoral. This move is exactly in phase (decadal scale) with the onset of ACC conditions (~6600 cal BC). Upon reaching the Aegean coastline, Neolithic dispersal comes to a halt. It is not until some 500 years later—that is, at the close of cumulative ACC and 8.2 ka cal BP Hudson Bay cold conditions—that there occurs a second abrupt movement of farming communities into Southeast Europe, as far as the Pannonian Basin. The spread of early farming from Anatolia into eastern Central Europe is best explained as Neolithic communities’ mitigation of biophysical and social vulnerability to natural (climate-induced) hazards.

<p><em>The new theory of abrupt climate change has yet to receive a response from those arguing for global policy coordination with the COP21 treaty or those who believe in country resilience. The only method to halt climate change with Hawking’s irreversibiity is to cut CO2s sharply now. But it will not happen, because of human regidity, opportunism with guile and institutional inertia. The global powers, acting for “WE” or “US” concentrate all attention upon petty matters.</em></p>
