North Atlantic cold blob disappears again

The North Atlantic cold blob that seems to have been with us for such a long time has warmed out since January and left a big pool of average SST behind it. Looking back through the archives, the cold blob last disappeared briefly in April 2020, before quickly reappearing again the next month. In March the Mediterranean and Baltic are warmer than average, as is the North Sea, English Channel and Bay of Biscay. I realise that these SST charts of the North Atlantic that I download from the IRI are fairly crude when compared to the ones I previously used, but they are the only ones freely available that I can find at the moment, which is a big shame because ocean temperatures is probably the biggest driver behind global warming.
