I think its nothern Canada only that has experience a very cold spring,
and the heading is a bit misleading as only a fraction of the arctic
has been affected. Take a look at this map:

Is interesting an interesting prospect that the Canada Geese that have
colonized Greenland in the last couple of decades amy breed successfully
andwhen the Canadian population fail.
Further north the Nares Strait on the NW of Greenland has been ice free
for weeks which may not have happened in historic times - even at the
end of summer it usually has quite a bit of ice:
