Change in global ocean heat content between the surface and 2000 meters of depth from 1958 to 2017 (top) and distribution of ocean heat content anomalies in 2017 (bottom). (carbonbrief.org)
A recently published estimate of Earth's global warming trend is 0.63 ± 0.28 W / m2, as calculated from ocean heat content anomaly data spanning 1993 - 2008. (deepclimate.org)
Time series of annual average global integrals of upper ocean heat content anomaly (1021 J, or ZJ) for (a) 0 — 100 m, (b) 0 — 300 m, (c) 0 — 700 m, and (d) 0 — 1800 m. Thin vertical lines denote when the coverage (Fig. 3) reaches 50 % for (a) 0 — 100 m, (b) 100 — 300 m, (c) 300 — 700 m, and (d) 900 — 1800 m. From Lyman & Johnson (2013) (skepticalscience.com)
