Very clearly shown in the the 0degree isotherm for January, see

Also consider that the "polar bear capital of Canada" is at the
same latitude as the south of England.

Interesting that the January 30degF isotherm pushes north in the North
Atlantic and North Pacific while the 70degF+ band in the tropics pushes
south at mid-Summer in South America, Australia and South Africa.
