Question place

Have at it -- questions welcome.  Answers probably of higher quality (from me, at least) if they're about ice, sea surface temperature, and related parts of the climate, or about running. 

Also suggestions welcome.

What is your question about this?

He did have a couple of oops, and I've commented there. But the conclusion holds -- this year's maximum global sea ice extent (he said area) is the lowest in the satellite era.

Perhaps you've read places like wuwt, where they add the northern hemisphere maximum to the southern hemisphere maximum and make claims about global sea ice increasing. It's a dubious claim even as it stands, but the thing is (regarding Appel's note), those two maxima are not at the same time.

mainly that he seemed prescient since there is still a fair bit of this year to be observed.

No psychic powers are required, just a knowledge of the seasonal cycle. Same as saying the Arctic max was (whatever it was in March-April) or the Antarctic minimum is (whatever it was in February). Cryosphere today has plots of the seasonal cycle. Link in right hand column of this page.
