Scientists who study the Arctic region consider this area to be an early indicator of global warming, because changes in this area are amplified by the high albedo of the snow and ice. This animation depicts the 28-year surface temperature trend over the Arctic region determined from data collected between August 1981 and July 2009. The warming and cooling regions are shown in steps of .02 degrees Kelvin per year from the regions of greatest change to the areas of least change. Blue hues indicate cooling regions; red hues depict warming. The neutral region of -.02 to +.02 is shown in white. Light regions indicate less change while darker regions indicate more. The temperature scale used ranges from -0.42 to +0.42 degrees Kelvin, although the minimum data value is -0.1825 degrees Kelvin per year while the maximum value is 0.4185.

This animation shows the 28 year temperature trend over the Arctic. Blue indicates cooling while red indicates warming. The colorbars (blue for cooler and red for warmer) have arrows depicting the range of colors being displayed.
