A quantitative measure of the rate at which fossil-pollen abundances changed over the last 18000 years at 18 sites spread across eastern North America distinguishes local from regionally synchronous changes. Abrupt regional changes occurred at most sites in late-glacial time (at =13700, ~12300, and
