Reconstructing past climates is challenging because pre‐instrumental observations are geographically sparse and proxy records are noisy; data assimilation offers one approach to address these limitations. Although such reconstructions are now widespread, the extent to which different proxy archives determine their ac...

Abstract. Paleoclimate data assimilation methods significantly enhance the accuracy, spatiotemporal continuity, and global relevance of climate reconstructions by integrating Earth system models with proxy records. In this study, we further improve the algorithm by implementing two adaptive strategies – adaptive observ...

Limited instrumental observations have created uncertainties in the rates and patterns of historical variations in tropical sea‐surface temperature, precipitation, and salinity. Coral archives are well suited to monitor past variations in the tropical oceans; in particular, the oxygen isotope composition (δ18O) has the...

Uncertainties in early 20th‐century observations limit understanding of the full range of internal climate variability and muddle understanding of climate system response to external forcing. Coral archives can provide high‐resolution information about historical sea‐surface temperatures (SSTs) and hydroclimatic change...
