Hydroclimate extremes like persistent droughts and intense rainfall threaten water and food security, infrastructure, and human health and lives. Development of appropriate polices and infrastructure to mitigate the impact of future hydroclimate extremes in Australia is challenging due to a combination of substantial natural climate variability and relatively short instrumental climate records (~100 years). These factors also make it difficult to determine the underlying climate dynamics associated with hydroclimate extremes, especially the onset and termination of droughts. This limits our ability to evaluate the representation of past, current, and future hydroclimate extremes in climate model simulations. Multi-century palaeoclimate proxy records sensitive to rainfall variability (e.g., tree rings) allow us to extend hydroclimate records beyond the short instrumental period, providing a longer-term context to the frequency, duration, and magnitude of hydroclimate extremes. However, suitable hydroclimate ...
