            "title": "Sea Ice Yearly Minimum 1979-2010 (SSMI data)",
            "description": "The continued significant reduction in the extent of the summer sea ice cover is a dramatic illustration of the pronounced impact increased global temperatures are having on the Arctic regions. There has also been a significant reduction in the relative amount of older, thicker ice. Satellite-based passive microwave images of the sea ice cover have provided a reliable tool for continuously monitoring changes in the extent of the Arctic ice cover since 1979. The ice parameters derived from satellite ice concentration data that are most relevant to climate change studies are sea ice extent and ice area. This visualization shows ice extent in the background and ice area in the foreground. Ice extent is defined here as the integrated sum of the areas of data elements (pixels) with at least 15% ice concentration while ice area is the integrated sum of the products of the area of each pixel and the corresponding ice concentration. Ice extent provides information about how far south (or north) the ice extends in winter and how far north (or south) it retreats toward the continent in the summer while the ice area provides the total area actually covered by sea ice which is useful for estimating the total volume and therefore mass, given the average ice thickness. For more information about these ice datasets, see The Journal of Geophysical Research VOL. 113, C02S07, doi:10.1029/2007JC004257, 2008 In 2007, Arctic summer sea ice reached its lowest extent on record - nearly 25% less than the previous low set in 2005. At the end of each summer, the sea ice cover reaches its minimum extent and what is left is what is called the perennial ice cover which consists mainly of thick multi-year ice flows. The area of the perennial ice has been steadily decreasing since the satellite record began in 1979, at a rate of about 10% per decade.This visualization shows the annual Arctic sea ice minimum from 1979 to 2010. A graph is overlaid that shows the area in million square kilometers for each year's minimum day. The 1979, 2007, and 2010 data points are highlighted on the graph. || ",

            "description": "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. || ",

            "description": "The Arctic region has been an area of scientific interest because it is expected that global warming signals will be amplified in the region because of ice-albedo feedback effect. 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.
