Apparently the North Poles isn't quite so cold as I had believed. It's possible the South Pole is much colder, but in Summer the high temperature at the North Pole is typically 0 and has been for some time, and it's not unusual for it to hit 22. Although it's hard to get good numbers because conditions there aren't actively monitored. Just showing my ignorance.
The arctic seas are actually at their warmest in September (that inertia again) which is significant to me as that was the time of year when I flew London to LAX and back in ‘81, and saw not one bit of open sea there, contrary to what some would have you believe, by altering the dates on satellite photos. Now that same North West Passage I flew over is wide open to shipping, even cruise liners!
The south pole is a lot cooler, but that is changing too: relatively warm moisture bearing air is getting further inland, leading to more precipitation, which then builds up to produce more ice, which eventually makes it’s way down to the sea.
With their usual ignorance, some climate change deniers argue that this shows things to be getting colder...
