Change in stored heat content in the upper 2,000 meters (1.2 miles) of the ocean from 1955-1959 to 2021-2025 using 'pentadal' data where each yearly value is the average of a five-year window centered on that year. Darkest orange areas show where heat content increased by 3 or more watts per square meter. Some areas have lost heat (blue), but not enough to offset increases everywhere else.
