Fig. 9. Precipitation and temperature reconstruction from the Carrowkeel–Keshcorran area between 4000 and 2600 BC compared to variations in the production rate of the cosmogenic isotopes 14C and 10Be and periods of human development and archaeological presence in Ireland. Grey shading denotes periods of warmer and drier conditions inferred from the Carrowkeel–Keshcorran archives. References: (1) Muscheler et al. (2005); (2) Vonmoos et al.
