Is there evidence for a 4.2 ka BP event in the northern North Atlantic region?
We review paleoceanographic and paleoclimatic records from the northern North Atlantic to assess the nature of climatic conditions at 4.2 ka BP, which has been identified as a time of exceptional climatic anomalies in many parts of the world.

| Summary: | We review paleoceanographic and paleoclimatic records from the northern North Atlantic to assess the nature of climatic conditions at 4.2 ka BP, which has been identified as a time of exceptional climatic anomalies in many parts of the world. The northern North Atlantic region experienced relatively warm conditions in the early Holocene (6–8 ka BP) followed by a general decline in temperatures after ~ 5 ka BP, which led to the onset of Neoglaciation. Although a few records do show a distinct anomaly around 4.2 ka BP (associated with a glacial advance), this is not widespread and we interpret it as a local manifestation of the overall climatic deterioration that characterizes the late Holocene. |
