2017 was the warmest year on record for the global ocean
2017 was the warmest year on record for the global ocean according to an updated Institute of Atmospheric Physics, Chinese Academy of Sciences (IAP, CAS; http://english. iap.cas.cn/) ocean analysis. The oceans in the upper 2000 m were 1.51 × 1022 J warmer than the second warmest year of 2015 and 19.19×1022 J above the 1981–2010 climatological reference period (Fig. 1). For comparison, total electricity generation in China in 2016 was 0.00216 × 1022 J, which is 699 times smaller than the increase in ocean heat in 2017.
