Climate Context
The 50 year long Great Drought of 1180 to 1140 BCE (Iron Age 1 period) is what ended the Bronze Age and the 5-year long Elijah drought of 845-840 BCE. The yellow gives the tree pollen level while the green gives the non-tree pollen level. (Langut and Finkelsein 2013)
Droughts Defined the Archaeological Periods in the Levant
(April 2, 2022) Droughts separate the archaeological periods in the Levant. States weakened by local droughts were often subject to raids right after the droughts by Mesopotamian empires which were unaffected due to their irrigation. Below is the latest widely accepted chronology proposed by Amihai Mazar in 2014 shown below:
Droughts According to Drought Chart
- 1180-1140 BCE - Great Drought
- 980 BCE
- 845-840 BCE - Elijah Drought
- 732 BCE - led to Assyrian invasion
- 605 BCE - led to Babylonian invasion

Tree Ring Data Where Available Provides Higher Climate Resolution
The juniper trees found in the tomb were Juniperus excelsa and Juniperus foetidissima.

Severe droughts seem to occur at a rate of 3 per every 100 years yet only multi-year droughts over a wide area lead to social instability due to lack of food. Three instances of the driest 6.25% of years occurring consecutively in Anatolia exist. Only the Bronze Age Collapse drought covered enough territory to be history changing. This data was assembled from tree rings and isotope ratios within those wood samples. (Manning and all, 2023)

Solar Eclipses
A solar eclipse should have been viewable in the Levant on June 15, 763 BCE. It was recorded by Assyrian observers in Nineveh (https://eclipse2017.nasa.gov/eclipse-history).
