Disappearance of Arctic Sea Ice


The image on the right shows sea surface temperatures on July 6 for the years 2014 to 2018 at a location near Svalbard (at 77.958°N, 5.545°E), with an exponential trend added based on the data.

The combination image below shows sea surface temperatures on July 6 for each of these years, with the location highlighted by a green circle:
2014:  -0.8°C or 30.6°F
2015:   6.2°C or 43.2°F
2016:   8.3°C or 47.0°F
2017: 14.4°C or 57.9°F
2018: 16.6°C or 61.9°F

The situation reflects the rapid decline of Arctic sea ice over the years and constitutes a stark warning of imminent sea ice collapse and its consequences for the world at large.

This compares to a sea surface temperature of 5°C or 41.1°F in 1981-2011 at that location (at the green circle). For more background on the warm water near Svalbard, also see the earlier post Accelerating Warming of the Arctic Ocean.

The images illustrate why sea ice has fallen dramatically in volume, especially so where sea currents push warm water from the Atlantic Ocean underneath the sea
