  3. Annual mean Arctic summer sea ice startofsatellitedata (IPCC 2013, Fig. SPM.2) • Annual mean Arctic summer sea ice extent decreased very likely with a rate of 3.5-4.1% per decade in 1979 – 2012 decrease was most rapid in summer (high confidence). • Data normalized to the satellite measured sea ice extent in 1979
