At about the 5:20 mark, Joe shows how a lack of ice at the North Pole in the summertime is really nothing unusual. Above is the North Pole in 1962 in the summertime.
Joe comments, “If this were occurring up there now, everybody would be going out of their minds. […] All the mainstream media and enviro-blogs would go crazy, right?”
Then Joe shows how the North Pole looks today:
Of course Arctic sea ice cover reaches it’s low in September and the above picture could change. The point is that an ice-free North Pole would be nothing new.
As Joe explains, Arctic summer sea ice extent is very much dependent on ocean cycles. Once the AMO goes negative again, we’ll likely be seeing ice extent like what we saw at the end of the 1970s.
