I have never seen this in all the years that I have looked at ocean temperatures. Of course, nobody else has looked. Why should they? I'm going a bit nuts in posting, I expect it's the wonderful party of cusp26. Everybody who is anybody is there, freezing with the Scottish weather. I hope they have lots of coal to burn.
You can see that the big turn-up of cold water, up the side of South America on the Pacific side. This must be the mechanism of a cold age. On the Atlantic, we have it going up Africa, and when it hits the equatorial belt, we'll have no heat.
People can warm themselves up with their beliefs. I am happy for them. I'm looking forward to lots of snow and 40 below temperatures. That was the winter of my discontent as a youth. All these young-uns were raised with warmth. Sad for them.
