Natural decadal climate variability (DCV) is one of the oldest areas of climate research. Building on centuries-long literature, a substantial body of research has emerged in the last two to three decades, focused on understanding causes, mechanisms, and impacts of DCV. Several DCV phenomena - the Pacific Decadal Oscillation or the Inter-decadal Pacific Oscillation, tropical Atlantic sea-surface temperature gradient variability, West Pacific Warm Pool variability, and decadal variability of El Niño-La Niña events - have been identified in observational records; and are associated with variability of worldwide atmospheric circulations, water vapor transport, precipitation, temperatures, river flows, crop productions, and transportation on the Mississippi River and hydro-electricity production in the U.S.; and worldwide oceanic circulations, salinity, temperatures, and fish catches.....
