A robust, reproducible multiproxy consensus approach validates and combines quantitative palaeotemperature reconstructions from three invertebrate groups (beetles, chironomids, and ostracods) and plant indicator taxa with qualitative implications of molluscs and small vertebrates. Compared with the present, interglacial mean monthly air temperatures were similar or up to 4.0°C higher in summer, but similar or as much as 3.0°C lower in winter; the Stratum C cold interval, following prolonged nondeposition or erosion of the lake bed, experienced summers 2.5°C cooler and winters between 5°C and 10°C cooler than at present. Possible reworking of fossils into Stratum C from underlying interglacial assemblages is taken into account. Oxygen and carbon isotopes from ostracod shells indicate evaporatively enriched lake water during Stratum C deposition. Comparative evaluation shows that proxy-based palaeoclimate reconstruction methods are best tested against each other and, if validated, can be used to generate more refined and robust results through multiproxy consensus. date: 2022-04-01 date_type: published publisher: Elsevier official_url: https://doi.org/10.1017/qua.2022.20 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1948724 doi: 10.1017/qua.2022.20 lyricists_name: Holmes, Jonathan lyricists_id: JAHOL84 actors_name: Holmes, Jonathan actors_id: JAHOL84 actors_role: owner full_text_status: public publication: Quaternary Research citation: Holmes, Jonathan; Horne, David; (2022) A terrestrial record of climate variation during MIS 11 through multi-proxy palaeotemperature reconstructions from Hoxne, UK.
