Sea Ice Decline Intensifies
Figure 5: Surface temperature anomaly
This image shows the difference between 2005 surface air temperatures in degrees Celsius (averaged for January through August) and the fifty-year mean (1955-2004) for the same months. The preponderance of positive values indicates an unusually warm Arctic in 2005. (NCEP/NCAR Reanalysis; NOAA-CIRES Climate Diagnostics Center )
