The North Atlantic Keeps Getting Colder

That cold blob in the North Atlantic just keeps getting bigger. A couple of months ago, it looked like this.
The KNMI climate explorer gives us this time series for the area involved (20 to 50W:40 to 60N):

For the last couple of years, SSTs have been tumbling and are now back to 1980 levels. Expect a cool summer if we get weather off the Atlantic.
It is also worth noting that the North Pacific warm blob has well and truly gone.
NOT A LOT OF PEOPLE KNOW THAT 
I wonder what the folks in Portugal or County Mayo notice having gone from a positive to a negative anomaly?

I dislike the map projection Unisys uses (others too) because it exaggerates the area in the high latitudes. These appear to be Mercator. A Robinson projection would provide a more realistic view.

John, here you can see SSTA and currents, as well as other weather and ocean data on a moveable globe.

You can zoom in and out with the mouse roller and click and drag to reposition the globe. They also have other projections, but I like the globe view. Click on the Earth label to choose other options.
The northern Pacific isn’t looking too toasty, either.

40 years in Salcombe. Town Councillor, business runner, dinghy racer. The Mean Spring High Tide is no high than in 1973. I have the support of one retired HM, several fishermen, etc., and I have sent this information everywhere I can think of. No-one has refuted it.
Maybe worth keeping a ‘weather eye’ on the waters off the coast of West Africa:-

Atlantic Equatorial mode? “…there may be a tenuous causal relationship between ENSO and the Atlantic Niño in some circumstances…..”

Yes, the death of El Nino plus warm waters off west Africa could mean an active tropical season coming up.
Agreed, but at present cold waters are upwelling along the coast:-

Similar, but lesser magnitude to what is happening off the west coast of South America.
http://earth.nullschool.net/#current/ocean/surface/currents/overlay=sea_surface_temp_anomaly/orthographic=-87.85,1.76,587/loc=-84.869,-1.953
Could be interesting to see how they develop, or fade….
Has any explanation been given for the exceptionally high anomalies off the US eastern seaboard? They’ve existed for quite some time.
Have not seen any, but have been wondering about it. Probably a modelling aberration caused by the meeting of the Gulf Stream and the Labrador Current.
I did a check with Earth Wind Map awhile back by picking a location and toggling between SST and SSTA. It was possible to get a +6.3C anomaly for a 19.2c actual and very close by a 19.4c actual would present an anomaly of 0.2c? Suppose it depends on how far south the Labrador Current is expected to be at a certain time of the year. But has anybody told the Labrador Current where it should be and is it listening?
Maybe it has decided to go north west in front of the Gulf Stream this year. Hence the cooling of the North Atlantic? Who knows? We just don’t have enough data to make a call.

But Paul, the keepers of the Great Consensus insist that only the slightly warmer water north of the cold blob matter.
The close minds of those keepers of the Great Consensus have spoken among themselves asserting ‘North Atlantic warming and its impact on the Greenland Ice Sheet and Arctic glaciers’
As they say before they even started —
Yes, that is the fatuous use of ‘unprecedented’ yet again!
Check the http://www.Climate4You.com data, under Oceans, for the North Atlantic, it shows a very clear cooling trend in the North Atlantic since 2007!
“Expect a cool summer…”
Thank God for that! My wife has got the dreaded hot flushes – and every time she hurls the bed-clothes off, she wakes me up!
Welcome to the club!
Could the cold North Atlantic be caused by excessive Actic sea ice loss? I ask because I have seen a Chinese paper that attributed cooling of surface waters off the N orth China coast since the 1990s to that cause.
Any links?
Paul , this is the paper, by members of the Chinese Climate Change Centre , published in Chinese science Bulletin (now just Science Bulletin) :

Spring surface cooling trend along the East Asian coast after the late 1990s
It is an open access article.
It’s interesting to see the cool anomaly all the way around Antarctica in their Autumn–and makes me curious as to whether we will see near-record SH sea ice this winter.
