Someone once said, "The Pacific sends us our weather, the Atlantic tells it what to do once it gets here". My concern is even if we do sort out the Pac, we still have to deal with the +AMO. It's nothing new, but the warm pool to our north east around the Gulf of Maine is throwing an extra wrench into things.
It would be helpful if we had some coastals or nor'easters to take some heat out of the Atlantic. But I guess this is all part of the feedback loop -- warm Atlantic = ridge, which = storms cutting to our north west, which = no coastals to churn up the waters, which = ridge...and on it goes.
No, I'm not part of the "it's-never-going-to-snow-again" crowd. But I do think it will take time (years?) to sort it out. I mean, even if we do get a Nino next year, they tend to suppress tropical activity in the Atlantic which leads to, you guessed it, a warm ocean for 2023-24.
