Structures constructed between 7,000-8,000 years ago (8,000-6,000 calibrated BCE)

Sea levels were significantly LOWER when these structures were built, and the rise was substantial. But was it really 22x faster? 🌊

New research suggests Mesolithic sea level rise was intense, but the math needs checking.

Key facts claimed:

- Structures constructed between 7,000-8,000 years ago (8,000-6,000 calibrated BCE)

- Sea levels were approximately 25 meters (82 feet) lower than present

- Sea level rise rate during Mesolithic was 8.4 millimeters per year

- Modern sea level rise is about 13 inches per century compared to 33 inches per century in Mesolithic

- Rapid sea level rise was about 2.5 times faster than current rates
