I think you may be reading more into my comment than I wrote. I was only talking about what we are seeing in the Show HN. I have no baseline to compare it to so all I can see is a map of the oceans with some areas red and some areas blue.

And over time the volume of blue reduces and changes to red, and even deeper red appears

It's generally accepted that red = hot and blue = cold, and there is a scale showing that anyway

It's quite obvious based solely on the site that this shows surface sea temperatures over 40 years, and it's far higher now than it was 40 years ago

But sure, just go on the "I'm only asking questions" crap.
