The British Quaternary sequence has an exceptionally rich record of Palaeolithic archaeology up to 1 Ma. In this study we re-investigate foraminifera based sea surface temperature (SST) reconstructions from the two marine cores records (ODP Site 980 and M23414), that are most relevant to the climatic history of the British Isles, consequently allowing the evolution of SST over the past 1 Ma to be studied. This is then compared to long-term changes with the British archaeological record in order to understand in greater detail the changing patterns of climatic forcing and the major climatic transitions that were the background environmental drivers against which patterns of early human occupation occurred. These include the Mid-Pleistocene revolution, the Mid-Brunhes Event and changing patterns of isotopic substage complexity. Significantly, however, the SST record indicates that MIS 15 to 13 was characterised by the most prolonged period of consistently warm conditions of the entire 1 Ma interval in the northeast Atlantic. This unique climatic period correlates with the first major proliferation of archaeological sites in northwest Europe. The paper concludes by discussing the significance of these climatic shifts for our understanding of early human occupation in this region.
