A series of abrupt climate events punctuated the transition from the ice age to the Holocene climate in the North Atlantic region, including cooling in the Younger Dryas and Preboreal Oscillation. It has been difficult to recognize this sequence elsewhere, particularly in terrestrial records, and thus the global extent of these events has been uncertain. Yu and Eicher (p. 2235) now report evidence for this sequence in lake sediments in Ontario, Canada, further within the interior of North America.
