17.04.2023Heat stored in the Earth system 1960–2020: where does the energy go?

• Earth has accumulated nearly 0.5 W (0.48 + 0.1 W) over every square meter of its surface over the past 50 years (since 1971).
• More recently (2006 to 2020), heating increased to more than 0.75 W (0.76 + 0.2 W) m^–2.
• Most heat entered the ocean (89 %).
• Remaining heat went into land (6 %), ice (4 %), and the atmosphere (1 %).
• Assessment of energy gained and disbursed represents a fundamental metric of changing global climate with implications for the ocean, land, ice, and atmosphere.
• Efforts such as these require sustained international cooperation on monitoring and research.
