I've been wondering whether a repeat performance is occurring. If so,
this could mean another cold winter or two for us, followed by a spell
of mild winters. Another effect would be an increase in East Greenland
ice for a few years, but this could also help towards more record lows
in the Arctic summer by reducing old ice amounts there.

I am hoping that the recent 2-3 "surprise" winters has already prompted
research into the causes.
