1. Paleoclimatic Evidence: The Soreq Cave Megadrought

High‑resolution speleothem analyses from the Southern Levant identify a multi‑decadal megadrought between ≈1250 BCE and 1100 BCE, the driest phase of the entire Bronze‑to‑Iron sequence in the region⁷. This signal is corroborated by parallel records from Cyprus, lake cores in Anatolia, and pollen sequences, all indicating synchronous aridity across the Eastern Mediterranean²⁴.

2. Impact on Centralized Palace Economies

Mycenaean Greece

• Palace sites such as Pylos exhibit abrupt abandonment of elite storage facilities and a sharp decline in bronze workshop activity during the drought window¹.
• The agrarian surplus that underpinned the Mycenaean redistribution model collapsed, eroding elite legitimacy and triggering internal unrest.

Hittite Empire

• Hattusa’s archival layers show a rapid cessation of long‑distance copper‑tin imports, reflecting the breakdown of trade routes that were already strained by reduced agricultural output¹³.
• The imperial bureaucracy, heavily dependent on tribute from drought‑affected provinces, lost fiscal capacity, accelerating political fragmentation.

3. Migration of the Sea Peoples

Egyptian inscriptions (e.g., the Great Karnak Inscription) first mention the Sea Peoples precisely during the peak of the Soreq drought⁴. Scholars interpret this temporal coincidence as climatically‑induced population pressure that pushed coastal communities to seek new resources, catalyzing the maritime raids and migrations recorded in the archaeological record¹⁶. While the causal chain is plausible, the literature emphasizes that climate was a significant but not exclusive driver.

4. Technological Transition: From Bronze to Iron

• The collapse of the bronze supply network (copper from Cyprus, tin from Anatolia) is directly linked to the drought‑triggered trade disruption¹⁵.
• Iron ore, more ubiquitously available in the Near East, became the pragmatic alternative. The earliest securely dated iron artifacts appear in 12th‑century strata that follow the megadrought interval, supporting a climate‑mediated technological shift⁵.

5. Integrated Multicausal Model

The consensus across the literature is that the megadrought acted as a primary stressor within a multicausal collapse model:

1. Environmental shock → agricultural failure → fiscal strain on palace economies.
2. Economic strain → breakdown of long‑distance trade (bronze inputs).
3. Resource scarcity → population displacement → Sea Peoples migrations.
4. Disrupted trade + local ore availability → accelerated adoption of iron metallurgy.

6. Research Gaps & Ongoing Debates

• Direct linkage between the Soreq isotopic record and the specific movements of Sea Peoples remains inferential; no single paper provides unequivocal proof, only a strong correlation¹⁶.
• The degree of climate determinism varies: some authors argue for a dominant climatic role, while others stress political, social, and possibly epidemic factors as equally pivotal¹².
• Chronological precision: Radiocarbon calibration and speleothem dating continue to improve, but exact year‑by‑year alignment of drought peaks with palace destructions is still debated².
