The Guardian article which I first noted has a typo of some sort in its link to a review, involving MIT climatologist Kevin Trenberth, of ocean heat content (OHC) data. I did a search for a recent Trenberth paper and have linked to a freely available page I believe to be the referenced review.
The study indicates that a number of the ways in which ocean heat content affects all of our daily lives are worsening and that there is a great deal of 'momentum' to this ocean warming effect which will take hundreds of years to undo.
Guardian article: Amount of ocean heat found to be accelerating and fuelling extreme weather events
Trenberth OHC data review: Improved Quantification of the Rate of Ocean Warming
