Ancient climate conditions cannot be directly measured, and are rather inferred from proxy data. Proxies are not direct indicators for changes in temperature, precipitation or evaporation, but rather provide indirect evidence for how temperature and hydrological changes impacted the Earth surface or biota. Most widely used climate proxies are geochemical or biological and provide information on mean annual temperature and mean annual precipitation. Here we utilise river sedimentary facies as proxies for precipitation intensity and intermittency, and produce a more realistic representation of past and future precipitation change.
