Snow Extent in the Northern Hemisphere now Among the Highest in 56 years Increases the Likelihood of Cold Early Winter Forecast both in North America and Europe
Snow extent in the Northern Hemisphere is much higher than average according to global estimates, and now among the highest ever observed. Winter forecast, especially in its early phase and in Europe, might be strongly influenced by such a large snow extent, although many other factors need...

Northern Hemisphere Sea Ice extent
Total sea ice extent on the northern hemisphere during the past years, including climate mean; plus/minus 2 standard deviations. The ice extent values are calculated from the ice type data from the Ocean and Sea Ice, Satellite Application Facility (OSISAF), where areas with ice concentration higher than 15% are classified as ice.
The total area of sea ice is the sum of First Year Ice (FYI), Multi Year Ice (MYI) and the area of ambiguous ice types, from the OSISAF ice type product. The total sea ice extent can differ slightly from other sea ice extent estimates. Possible differences between this sea ice extent estimate and others are most likely caused by differences in algorithms and definitions.
Data set
The sea ice extent data is composed by a Climate Data Record (CDR, 1979-2015), an Interim CDR (ICDR, since 2015 with 16 days delay) and a daily product to cover the period between the ICDR and today. Clic here for a detailed explanation.

looks to me as if sea ice is above the last five year average.
but you keep on waiting for that NOAA report.
