Arctic Sea Ice Comparison from 1920s

Danish Arctic Sea Ice Record Comparison verses recent satellite images, tells a story of a changing climate.

Arctic Sea Ice animation of expanse changes from the 1920′s and 1930′s

An animation of the Arctic Sea Ice expanse changes from the 1920’s and 1930’s compared with recent data. Sadly the Second World War happened and put an end to the research for awhile.

If one focuses on the white (ice) area relative to the blue (ocean) region–It should not be hard to notice a significant change when compared to the 2012 data.

Sources: Danish Meteorological Institute’s sea ice maps from 1920 to 1939 during the month of August and US National Snow and Ice Data Center’s satellite-derived sea ice concentration image for August 2012

Even though some data is missing (from 1922 and after the start of WW2) and is currently not available it should still be possible that some people will be able to connect the dots to see a trend.
