Topic: Tree Rings

The importance of iodine for thyroid health and protection against environmental radiation is discussed, citing the Japanese diet as a model for iodine repletion. DeCarle and Carlwood look at historical data from tree rings and ice cores suggesting that the Black Death coincided with major environmental anomalies like volcanic activity or comet impacts. They argue that these environmental stressors, rather than just a "plague," were responsible for mass mortality.

The authors challenge the traditional narrative that the Black Death was caused by rat fleas. Citing dendrochronologist Mike Bailey, they argue that tree ring data and ice cores show the Earth's atmosphere was poisoned by comet debris in the 14th century. They suggest that environmental toxins, rather than bacteria, caused the mass die-offs of humans and fish during that period.

Randall Carlson links the legendary Battle of Camelot (dated circa 539 AD) to a real-world climatic disaster beginning in 536 AD. Scientific evidence from tree rings and ice cores shows a period of extreme cooling, likely caused by volcanic activity or impacts, which led to global crop failures. This environmental collapse facilitated the spread of the Justinian Plague, which decimated the population of Europe and initiated the Dark Ages.
