Your theory has some problems. *Number one being the Antarctic has been above the 20 year average for almost two years now. *Number two is of course that the Arctic is trending along at pretty normal.

As I said , I could be wrong. Nevertheless your arguments need some checking too :
1) The chart has the title "extent" what about the depth?
2) Most of the melting doesn't come from the artic (where most of the ice is already under the sea, but from greenland, and greenland has been melting steadily.*
3) Th other source of the melt is west antartica .
... your turn.
Antarctic sea ice is actually thicker than the AGW cultists thought. *In fact this one discovery DOUBLED the known extent of Antarctic sea ice.

Greenland again huh? *We'll ignore the fact that it was much warmer 800 years ago and go with the 150 year cycle that has been deciphered as the cause of the ice melt.
"Jet stream changes cause climatically exceptional Greenland Ice Sheet melt
The research team at the GrISResearch from the University of Sheffield has shown that unusual changes in atmospheric jet stream circulation caused the exceptional surface melt of the Greenland Ice Sheet (GrIS) in summer 2012.
An international team led by Professor Edward Hanna from the University of Sheffield’s Department of Geography used a computer model simulation (called SnowModel) and satellite data to confirm a record surface melting of the GrIS for at least the last 50 years - when on 11 July 2012, more than 90 percent of the ice-sheet surface melted. This far exceeded the previous surface melt extent record of 52 percent in 2010.
The team also analysed weather station data from on top of and around the GrIS, largely collected by the Danish Meteorological Institute but also by US programmes, which showed that
several new high Greenland temperature records were set in summer 2012.
The research, published today in the International Journal of Climatology, clearly demonstrates that the record surface melting of the GrIS was mainly caused by highly unusual atmospheric circulation and jet stream changes, which were also responsible for last summer's unusually wet weather in England."

West Antarctica is one third of the continent. *However the warming is only occurring on the peninsula, and even there the rise is covered by the error bands. *The warmest period averages 1-2 degrees C and has been that way since measurement began. *The "warming is detectable only in statistics....not on the thermometers.
Because the Antarctic Peninsula, which reaches north of the Antarctic Circle, is the most northerly part of Antarctica, it has the mildest climates within this continent. Its temperature are warmest in January, averages 1 to 2°C, and coldest in June, averages from -15°C to - 20°C. Its west coast from the tip of the Antarctic Peninsula south to 68 degrees South, which has a maritime Antarctic climate, is the mildest part of Antarctica Peninsula. Within this part of the Antarctic Peninsula, temperatures exceed 0°C for 3–4 months during the summer, and rarely fall below -10°C during the winter. Farther south along the west coast and the northeast coast of the peninsula, mean monthly temperatures exceeding 0°C for only 1–2 months of summer and average around -15°C in winter. The coast of the Antarctic Peninsula south of 63°S is generally much colder with mean temperatures exceeding 0°C for only 0–1 months of summer and winter mean temperatures ranging from –5 to –25°C. The colder temperatures of the southeast, Weddell Sea side, of the Antarctica Peninsula are reflected in the persistence of ice shelves that cling to the eastern side.[9][10]
Precipitation varies greatly within the Antarctic Peninsula. From the tip of the Antarctic Peninsula south to 68 degrees South, precipitation averages 35–50 cm per year. a good portion of this rain falls as rain during the summer, on two-thirds of the days of the year, and with little seasonal variation in amounts. Between about 68°S and 63°S on the west coast of the Antarctica Peninsula and along its northeast coast, precipitation is 35 cm or less with occasional rain. Along the east coast of the Antarctic Peninsula south of 63°S, precipitation ranges from 10–15 cm. In comparison, the subantarctic islands have precipitation of 1–2 m per year and the dry interior of Antarctica is a virtual desert with only 10 cm precipitation per year.[10
