Arctic Sea Ice Extent Aug 27 2014 – Drop of Only 18,000 Over Last 2 Days
Arctic Sea Ice Extent Aug 27 2014 – -1,069,000 sq km below the 1981-2010 mean. Data for Day 238. Data here.
Drop of Only 18,000 Over Last 2 Days. 2014 seems to be most similar to 2009 and 2013.
2009’s minimum was 5.05488 million sq km on day 255
2013’s minimum was 5.07709 million sq km on day 256
But I’m not making a prediction.
