11 January 2023 Another Year of Record Heat for the Oceans, Lijing Cheng et al 
Sea surface temperature, ocean heat content , ocean acidification and de-oxygenation are record high, increasing at record rates
Over 90% of added greenhouse gas emissions heat goes to the oceans. The rate is now equivalent to exploding 7 Hirosohima atom bombs every second 
Accelerating ocean deoxygenation 
Accelerating ocean acidification
Acidification is expressed as pH​ which is inverse 
Record 2023 Sea surface
​temperature increase 
Accelerating ocean heat (content)
Ocean heat accelerating at all levels, now penetrating to the ocean floor
