Insane SST anomalies in north Atlantic

Check out the latest Reynolds map of SST anomalies for the Atlantic:

There are some serious 3C above normal areas, large areas, showing up in the far northern Atlantic. I have no idea what this means as far as global weather but am wondering why this is the case. Why are such warm anomalies showing up so far north? And look south in the tropics, nothing really jumps out as being too much above normal...nothing like 2004 and 2005 for sure. Just something that caught my eye. Any comments?

The anomalies up there seem to be inversely proportional to anomalies in the various ENSO sectors, though that doesn't explain 2004 and 2005.
