The large‐scale meridional overturning circulation named after George Hadley spans half the area of the globe, and variability within this system affects the lives of billions of people. Along with the large‐scale zonal tropical cells named after Sir Gilbert Walker, the Hadley and Walker Circulations comprise fundamental regulators of the Earth's energy budget. Although Hadley Circulation is a well‐known concept, surprisingly little attention has been paid to understanding both short and long‐term variability of the system. To address this issue, 60 scientists from 10 countries met at the University of Hawaii in Honolulu to consider evidence for changes in Hadley Circulation on different time scales.
