What happened around 3,000 BC? A lot.
Rain storms, climatic oscillation. Millennial-scale warming terminates with a period of climatic disturbance and flooding in the lower latitudes (Nile, Arizona, Morocco, Israel, Mesopotamia), followed by a drought; general, worldwide, climate-driven shock to early societies living in “edenic” geography of plenty with “fertile crescent” survivors organizing into more centrally administered culture based on irrigation.
3250 BC: Global; Stormy weather
Beginning of 1000 yrs wet, stormy weather. A neoglacial period characterized by wetter, stormier conditions; starting between 5000 and 4000 years BP and extending to about 3500 yrs BP (Enzel, Quat R 1992)
3199 BC: Europe; Irish oaks
Tree rings in Northern Ireland are narrow in 1153 B,c 1628 B,c 3199 B,c and 4377 BC. The 3199 BC value is associated with an acidity peak in Camp Century ice cores dated at 3150 B,c demonstrating unquestionably that adverse weather conditions, probably due either to volcanic eruption or meteoric impact, occurred at this time. Other narrow years are associated with frost rings observed in California bristlecone pines and with eruptions of Icelandic (Hekla 3 in 1159 BC) and Aegean (Santorini in 1628 BC) volcanoes.

3150 BC: Mesopotamia; The Flood
The Flood 3150 BC(?). Abrupt cooling at higher latitudes, possibly related to oceanic effects, especially in Northern Europe, corresponding to peak of megalith cultures. Probable oscillation in sea level shortly before 3000 BC followed by 10-15 ft. alluvial deposition in river valleys.
3113 BC: Mexico; Mayan recreation
Last Mayan date of recreation of the world following The Flood , Aug 12, 3114 BC.
3100 BC: Egypt; Egypt, Unification
3100 BC: Greenland; GISP ice core
rapid climatic change shown on GISP ice core Science 12/22/95.
