Short summary
We review paleoceanographic and paleoclimatic records from the northern North Atlantic to assess the nature of climatic conditions at 4.2 ka BP. There was 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 characterized the late Holocene.
