According to data from NASA’s QuikSCAT satellite, between 2004 and 2005 the Arctic lost an unprecedented 14 percent of its perennial sea ice (shown in white)—some 280,000 square miles (725,000 square kilometers), or an area the size of Texas.

The right image is an EOS Aqua AMSR-E ice concentration acquired on 24 August 2005. (Courtesy: Leif Toudal Pedersen). The pink colour is consistent all the way around the pole (black hole), indicating pack ice with 100% ice concentration. The left image is acquired on 24 August 2006. There is a significant extent of leads – fractures and openings in the sea-ice cover – just below the pole (with British Isles shown for scale), seen by the high concentration of yellow, orange and green colours, signifying low ice concentrations.
