It's actually an interesting report...nice to read something that doesn't scream carbon dioxide GW for a change.
This July's major loss of sea ice will amplify sea ice loss the remainder of the summer, due to a positive feedback loop. As sea ice melts in response to rising temperatures, more of the dark ocean is exposed, allowing it to absorb more of the sun's energy. This further increases air temperatures, ocean temperatures, and ice melt in a process know as the "ice-albedo feedback" (albedo means how much sunlight a surface reflects). The July 2007 ice loss may mean that a runaway "ice-albedo feedback" has taken hold, which will amplify until the Arctic Ocean is entirely ice-free later this century. Other scientists will disagree, but I believe that such a runaway ice-albedo feedback has taken hold.
