Here’s a sea ice comparison app/webpage:

[Link: igloo.atmos.uiuc.edu…]

It’s set up to compare 11/2/79 and 11/1/09

That is one of my favorite web sites. And if you compare Jan1, 1979 to Jan 1, 2009, they are nearly the same.

Discussions of a viable northwest passage generally omit that the Arctic ocean re-freezes in the winter. The blogs of the yachts that try the northwest passage tell stories of barely making it before the winter ice starts growing in September.
