🌋 Irish bog oaks showed stunted growth for 2 decades, & tephra cores from Scotland/Ireland pointed to Iceland's Hekla volcano erupting around 3,000 years ago. Could a volcanic winter explain Bronze Age collapse? Evidence remained inconclusive 🤔
Key facts claimed:
- Late Bronze Age collapse noticed in 19th century when destruction sites in Greece matched Egyptian records of Sea Peoples
- Climate change and volcanic eruptions proposed as causes starting in early 20th century
- 1989 study examined Irish bog oaks showing two decades of limited growth
- Volcanic tephra recovered from core samples in Scotland and Ireland
- Hekla volcano in Iceland thought to have erupted around 1100 BC
