Intensified decadal variability in tropical climate during the late 19th century

Ault, Toby R; Cole, Julia E.; Evans, Micheal N; Barnett, Heidi; Abram, Nerilie; Tudhope, A W; Linsley, Braddock K


To evaluate and extend the record of decadal climate variability, we present a synthesis of 23 coral oxygen isotope records from the tropical Indo-Pacific that extends back to A.D. 1850. Principal components analysis (PCA) on detrended records reveals a leading pattern of variance with significant interannual (3-5 year) and decadal (9-14 year) variability. The temporal evolution and spatial pattern of this variability closely resembles the El Nino/Southern Oscillation (ENSO) pattern across both...[Show more]
