About 400 new 14C ages have been analysed on 15 trees sampled at annual resolution. The resulting ”14C record exhibits an abrupt spike occurring in a single year at 14	30014	299	cal	yr	BP and a century-long event between 14 and 13.9	cal	kyr	BP. In order to identify the causes of these events, we compare the Drouzet ”14C record with simulations of ”14C based on the 10Be record in Greenland ice used as an input of a carbon cycle model. The correspondence with 10Be anomalies allows us to propose the 14.3	cal	kyr	BP event as a solar energetic particle event. By contrast, the 14	cal	kyr	BP event lasted about a century and is most probably a common Maunder-type solar minimum linked to the modulation of galactic cosmic particles by the heliomagnetic field. We also discuss and speculate about the synchroneity and the possible causes of the 14	cal	kyr	BP event with the brief cold phase called Older Dryas, which separates the Bølling and Allerød millennium-long warm phases of the Late Glacial period.","pubRank":"1"}],"site":[{"NOAASiteId":"59821","siteName":"Drouzet
