By "all-time" I mean since 1979, the time for which we have consistent and comparable satellite data.

Remember, as I said, this measure doesn't tell us all that much about the health of either Arctic or Antarctic regions, if only because the seasons move in opposite directions (nevertheless, the Global sea ice trend is down). It's just an interesting statistical factoid.

However, climate risk deniers often use the Global sea ice metric as an argument that nothing is wrong and AGW is a hoax. In other words, the recent growth in Antarctic sea ice offsets the loss of Arctic sea ice (it doesn't), even though the poles are literally worlds apart and are pretty much incomparable (except for the sea ice bit).

Using this logic, it would seem that this new record minimum means there is something wrong with sea ice and AGW isn't a hoax. I wonder how they will spin this one. If they report it to their loyal readers, that is.

I'm afraid we'll have to look it up for ourselves. Their "loyal readers" don't spin on Habzone any more.
