Images from "Ice-free Arctic Ocean possible in 30 years, not 90 as previously estimated"

|  | | University of Washington/NOAA | | The heavy red line is the sea-ice extent observed since the 1950s. Six models that most accurately depict that ice extent are shown with thin colored lines. The heavy blue line is the average of those six models and projects ice-free Septembers in 20 to 30 years. In contrast, the heavy yellow line is the average sea-ice extent of all 23 models including outliers unable to reproduce current sea-ice conditions. |
