When using 1991-2020 climatology, the peak was in April and "only" 4 Standard Deviations:
The Sea Surface Temperature dataset from @NOAA goes back further, so here we can use the 1901-2000 climatology (which some like to use as a preindustrial baseline):
Absorbed Solar Radiation and Earth's Energy Imbalance are off the chart, leading to acceleration of regional and global warming!
Sea Surface Temperatures are increasing most where sulphur emissions from shipping reduced most and where the increase in absorbed sunlight is most apparent.
People living in and around this area might want to know that the amount of Absorbed Solar Radiation in this area increased to +4.3 W/m² in 2023 since 2000-2009!
This is more than the greenhouse gas forcing from all greenhouse gases we've added to the atmosphere since 1750!
+4.3 W/m² for over 10% of the Earth's surface!
If people understood what this means, it would be front page news everywhere.
We all know this won't be covered anywhere.
These +4.3 W/m² over 54,340,000,000,000 m² added 7.4 ZJ of additional heat in the 12 months of 2023!:
