Global Sea Ice Sets a Record: Lowest Annual Minimum for Extent
Global sea ice extent is just the sum of Arctic SIE and Antarctic SIE. Since 1979, the trend in the annual minimum of global SIE is -320,000 km2/decade (-1.8% per decade). This year's minimum could still go lower.
(The data are from NSIDC, and are preliminary ("recent," see below) since 1/1/15.)

Here's how the daily anomalies look:
The trend here is -230,000 km2/decade. Baseline is 1981-2010.
