Such effect is associated with the high albedo of snow and sea ice covered areas compared to that of ice free ocean and land areas. This animation depicts the 28-year winter seasonal surface temperature trend over the Arctic region determined from data collected during the months of December, January and February between 1981 and 2009. In this animation, the warming and cooling regions are revealed in steps of .02 degrees change per year starting with the regions of greatest change and progressing to the areas of least change. Blue hues indicate cooling regions while red hues depict warming. The neutral region of -.01 to +.01 degrees is shown in white. Brighter regions indicate greater temperature change while light regions indicate less. On the left side, the colarbar shows cooling temperatures ranging from -0.42 to zero degrees Kelvin, while the colorbar on the right shows warming temperatures ranging from zero to +0.42 degrees Kelvin per year. A moving bar beside each colorbar indicates the range of data values being displayed. || ", "release_date": "2010-01-05T00:00:00-05:00", "update_date": "2023-05-03T13:54:25.039475-04:00", "main_image": { "id": 494844, "url": "https://svs.gsfc.nasa.gov/vis/a000000/a003600/a003676/winterTrend_720p60.0660.jpg", "filename": "winterTrend_720p60.0660.jpg", "media_type": "Image", "alt_text": "An animation revealing the 28 year winter temperature trend, showing regions of greatest change first.
