NOAA Paleoclimatology Program and World Data Center for Paleoclimatology WDC for Paleoclimatology Mission: To provide long-term climate and other environmental data needed to understand and predict climate variability and change “The farther backward you can look, the farther forward you are likely to see” -- Winston Churchill ARTS 2001, Noumea, New Caledonia
What is ARTS? • ARTS is an official project of the IGBP/PAGES • International Geosphere-Biosphere Programme • Past Global Changes Programme • The ARTS initiative promotes the synthesis of paleoclimatic data with instrumental and modeling perspectives to address uncertainties in our understanding of tropical climate variability and its impacts. • ARTS requires a wide array of annually resolved/datable paleoclimatic data from the tropics and tropically driven locations. ARTS 2001, Noumea, New Caledonia
Windows into Past Centuries • ARTS synthesis project "Climate of the Nineteenth Century,” (CNC) would coordinate analysis of climate of the past several centuries. • Other ARTS work would reconstruct climate from earlier times such as the mid-holocene or past glacial or interglacial periods. • An important target: to reconstruct indices of large-scale climate systems from pre-instrumental periods. ARTS 2001, Noumea, New Caledonia
Windows into Past Centuries Background colors indicate mean instrumental SST field. Records at pink dots span the interval 1895-1990; white dots indicate shorter records. SST trends are calculated over the 1895-1990 period and are indicated parenthetically in °C per 100 years. (after Bradley et al. in prep., PAGES Synthesis Volume). ARTS 2001, Noumea, New Caledonia
Windows into Past Centuries • The graph shows a summary of annual resolution coral d18O isotope records, normalized to the 1923-1980 period (thick line denotes 7-year smooth ). • The data show general trends consistent with globally warmer/wetter conditions. (after Bradley et al. in prep., PAGES Synthesis Volume). ARTS 2001, Noumea, New Caledonia
a b c d Windows into Past Centuries SSTs reconstructed from coral d18O data at 13 sites. • (a) Leading spatial pattern observed in coral data (ENSO-like mode, in dimensionless units); shading indicates 90% significance. • (b) The time series of that pattern (degrees C). • (c and d) series of second pattern: similar to global warming signal. After Evans et al. (2000) Paleoceanography, 15 ARTS 2001, Noumea, New Caledonia
Data-Model Comparisons • Comparison of energy balance model with instrumental data shows good fit over most of 1000 years • Particular discrepancies seen in 19th, early 20th centuries ARTS 2001, Noumea, New Caledonia After Crowley (2000), Science 289

Windows into Past Millennia Climate researchers need high-resolution records from targeted Holocene, last-glacial and last interglacial intervals to understand how the climate system responded to boundary conditions substantially different from those prevailing today.
