Change in heat content in the upper 2,300 feet (700 meters) of the ocean from 1993-2020. Between 1993–2019, heat content rose by up to 6 Watts per square meter in parts of the ocean (dark orange). Some areas lost heat (blue), but overall, the ocean gained more heat than it lost. The changes in areas covered with the gray shading were not statistically significant.
