This is a little surprising, because historically global sea ice extent is quite high, on an annualized basis:
and it's mostly because Antarctic sea ice extent is taking a little hiatus this winter:
At the moment, Arctic SIE is 3.9% below last year's extent, and Antarctic SIE is 6.4% lower.
Data from NOAA: Arctic SIE, Antarctic SIE
I had noticed that. There appears to be a shift in where the sea ice extent is growing in Antarctica. Some knock-on effect from the El Nino perhaps?
