Artic sea ice coverage, 1980 C014 / 4710
Artic sea ice coverage, 1980. Map showing the changes in Arctic sea ice coverage from 1st November 1979 to 31st January 1980. Multi-year ice is shown in bright white, while average sea ice cover is shown in light blue to milky white. This study found that perennial ice extent has been shrinking at a rate of -12.2 per cent per decade, while its area is declining at a rate of -13.5 per cent per decade. These numbers indicate that multiyear ice is declining faster than the perennial ice that surrounds it. Image compiled using data from passive microwave sensors on NASAs Nimbus-7 satellite and by the Special Sensor Microwave Imager/Sounder (SSMIS) from the Defense Meteorological Satellite Program (DMSP)

EDITORS COMMENTS
This print showcases the dramatic changes in Arctic sea ice coverage from November 1979 to January 1980. The map, compiled using data from NASA's Nimbus-7 satellite and the Defense Meteorological Satellite Program (DMSP), reveals a striking contrast between multi-year ice and average sea ice cover. Multi-year ice is depicted in bright white, while the lighter shades of blue to milky white represent the average sea ice extent. The study accompanying this image brings alarming findings to light: perennial ice extent has been steadily diminishing at an astonishing rate. Over each passing decade, it has been shrinking by -12.2 percent, with its area declining even faster at -13.5 percent per decade. These numbers indicate that multi-year ice is receding more rapidly than the surrounding perennial ice. The implications of these observations are significant and point towards a concerning trend in our changing climate. As global warming continues unabated, the Arctic region faces unprecedented challenges due to melting polar ice caps and receding sea ice cover. This thought-provoking photograph serves as a stark reminder of humanity's impact on our planet Earth. It highlights both the urgency for action against climate change and the importance of ongoing environmental science research aimed at understanding these complex processes shaping our world today.
