Rapid oceanic and atmospheric changes during the
12,900 years ago, was a period of rapid cooling in the Northern Hemisphere, driven by large-scale reorganizations of patterns of atmospheric and oceanic circulation1–3. Environ-mental changes during this period have been documented by both proxy-based reconstructions3 and model simulations4, but the...
