In 1956, Maurice Ewing and William L. Donn published “A Theory of Ice Ages” in Science on June 15. The paper reported an abrupt increase in Atlantic surface-water temperatures about 11,000 years ago, describing it as the most significant temperature change of the previous 60,000–80,000 years, and noted comparable changes earlier in the Pleistocene. Their proposed mechanism was an open Arctic “polar sea” whose freezing and reopening helped drive glacial cycles. They treated the abrupt shifts as explicable within their uniformitarian ocean-ice model, without requiring a catastrophe.
