In the long‐record of hurricane activity, which stretches back roughly 7500 years, the frequency of large tropical cyclones has varied, with distinct periods of elevated or depressed activity lasting hundreds to thousands of years. Of the 12 sites that provide the basis for this record, 6 measure the activity in the tropical North Atlantic, 1 serves as a history of the northwestern Pacific, and 5 sites around Australia represent the southwestern Pacific Ocean and the Indian Ocean. In previous research, scientists used the individual records from northern hemispheric sites to investigate the connection between long‐term tropical cyclone activity and climate systems such as the El Niño Southern Oscillation (ENSO). Nott and Forsyth , however, used the records from all 12 sites to ascertain a measure of long‐term global hurricane activity.
