Like like you post was ‘Arctic ‘ sea ice, not global sea ice.
Global Sea Ice

Does this mean that Pres**ent Trayvon Obama made the sea go down and our planet begin to heal? /s
There are 2 measures, “area” and “extent”. The “extent” is the portion where the sea ice is 15% or greater. The “area” is just the portion which is 100% covered. Also there are measurements from different groups, U. of Illinois, NSIDC (National Snow and Ice Data Center)and the Danish Meterological Institute (which is above average now). Plus the graph in your link is just the Arctic - because the Antarctic is above normal it brings the GLOBAL area above normal.
