About 7,500 years ago, marine waters began reconnecting with the formerly freshwater Black Sea through the Bosphorus. Columbia geologists William Ryan and Walter Pitman argued in 1997 that this reconnection was catastrophic: their model compared the inflow's force with 200 Niagara Falls and estimated up to 27,000 square miles could be inundated. Sediment cores show freshwater deposits beneath marine mud, but later studies dispute the speed and scale of the flood, with some favoring gradual reconnection. The video argues that displaced people carried flood stories across Europe and the Middle East and that this history inspired Noah's Flood and the Gilgamesh tradition; that link is not established.
BLACK SEA flood hypothesis: catastrophe and Noah connection remain disputed

Key facts
- Before about 7,500 years ago, the Black Sea was a large freshwater lake; marine waters later reconnected with it through the Bosphorus.
- Columbia University geologists William Ryan and Walter Pitman published their catastrophic-flood hypothesis in 1997.
- Ryan and Pitman's model proposed a high-velocity inflow with the force of about 200 Niagara Falls and estimated that up to 27,000 square miles could be inundated. These are model estimates.
- The cited results do not establish the video's 300-foot channel or "almost overnight" timing. The Science summary's 1–2 figure concerns coastal inhabitants moving inland, not a one-mile-per-day flood rate.
- Sediment cores show freshwater deposits beneath marine mud, consistent with a lake-to-sea transition but not proof of a sudden flood.
- The speed and scale remain disputed; some later reconstructions favor gradual reconnection and a rise closer to 100 feet than 260 feet.
- Flood narratives recur across cultures, including the Gilgamesh epic and Genesis. The video argues that Black Sea refugees spread those stories and inspired Noah's Flood; that cultural link is not established.
