A new international study published Friday in Advances in Atmospheric Sciences reports that the world’s oceans took in more heat in 2025 than ever before, making it the ninth straight year of record-high ocean temperatures.
The upper 2,000 meters of the global ocean gained approximately 23 zettajoules of heat energy compared to 2024, an amount equivalent to 37 years of global energy consumption at 2023 levels, or the explosive force of 12 Hiroshima atomic bombs detonating every second throughout the entire year.
