Models show Arctic sea ice nearly disappearing in the summer by 2045

Jeff Masters' wunderblog has a special section with a very well-explained description of what is going on in the Arctic with regard to sea ice melt and the causes:

Figure 5. September Arctic sea ice extent observed in 1979 (yellow line), and 2005 (white area). The predicted coverage of sea ice by Holland et al. (2006) is shown for 2015 (red line) and 2040 (green line). Their model predicts that sea ice in summer by 2040 will occur only in narrow bands along the Canadian Arctic coast. However, there will still be about 50% sea ice coverage in winter.
