The National Oceanic and Atmospheric Administration (NOAA) recently released its annual State of the Arctic Report, showing that the Arctic region is changing rapidly in a number of ways. Scientists say the changes make it unlikely the Arctic will return to its former state.
The images below show some of the ways the Arctic is transforming.
The map above shows changes in the length of the growing season in high northern latitudes based on satellite observations of “greenness” between 1982-2008. Green indicates places where the growing season increased by up to 2 days per
A massive ice sheet almost completely covers Greenland, and as summer temperatures climb and days lengthen, parts of the ice sheet surface usually melt, especially at lower elevations near the coast. The summer of 2012, however, brought far more extensive melt than anything observed in the satellite record. In July 2012, surface melt extended over nearly the entire ice sheet. The melt was not just around the edges, but also on the high-elevation center. These images compare surface-melt conditions on the Greenland Ice Sheet on July 1, 2012 (left), and July 11, 2012 (right).
