The Institute's Climate Reanalyzer also has some visual data of historical daily sea surface temps that is referenced quite a bit these days.
Data only stretches back to the late 70s/early 80s, but many of the hottest trending years are within the last decade.

You have to look back 3 million years to see the same GHGe concentrations and temperatures that earth is reaching now (the two are closely correllated throughout most of earth history, and easily explained by science - the greenhouse effects, and the thin earth surface and atmosphere mostly acting as a closed system).
We see that both ice, ocean and air are heating up and accellerating as of 2023. What is observed now is in-line with projections, such as summed up in this hobbyist article (taken with some grains of salt): https://medium.com/@samyoureyes/the-busy-workers-handbook-to...
Even if some of what is summarized on the notes linked above may be exhaggerated, it seems this is now happening sooner, faster and more relentless than IPCC and scientific consensus have found so far.
Note that any averages or aggregates on measurements, such as those IPCC and climate scientists use, will lag reality by approximately half the period used. So using multi-year averages means we will already be too late when long-term averages show accelleration, even if final calculations will be more stable ("smoother") by using averages. Of course there's no way to really "cheat" this, but that means when we now see we are in uncharted territory, it should be taken seriously.
