  1. There is no Antarctic graph or global graph (contrary to the title and tags). This has been happening frequently for a while.
    Please correct the title and tags (or add the missing graphs).

  2. Arctic sea ice extent correlates closely* with the AMO, especially if you can get the data from 1972 to 1979, which has been left out of the official series. You’ll see what I mean when you include it.

    No surprise that the AMO is a major driver since it is sea surface temperature in the northern Atlantic. And of course the AMO is cyclical with about a ~60 year period…but we’ve only seen the most recent 30 year rising phase since the satellites only went up right at the bottom of the cycle.

    (*Technically it anticorrelates since rise in the AMO = a fall in sea ice extent.)
