Ocean heat content and Earth's radiation imbalance

Earth’s radiation imbalance is determined from ocean heat content data and compared with results of direct measurements. Distinct time intervals of alternating positive and negative values are found: 1960– mid-1970s (−0.15), mid-1970s–2000 (+0.15), 2001–present (−0.2 W/m 2 ), and are consistent with prior reports. These climate shifts limit climate predictability.
