| Sources | Title (cont.) Shorter-term variability is shown in the lower panels. Age is relative to present = 1950. Accumulation doubled at the end of the Younger Dryas cold event, as shown in the middle-lower panel, and a somewhat larger change occurred almost as rapidly at the onset of the Bolling warm event.
