I was thinking that it was too early to say this, since in past years what looks like a minimum can sometimes be reversed by some additional melting.

Here is what they say:<\/p>\n<blockquote><p>On September 11, Arctic sea ice reached its likely minimum extent for 2015. The minimum ice extent was the fourth lowest in the satellite record, and reinforces the long-term downward trend in Arctic ice extent. Sea ice extent will now begin its seasonal increase through autumn and winter. In the Antarctic, sea ice extent is average, a substantial contrast with recent years when Antarctic winter extents reached record high levels.<\/p>\n<p><em>Please note that this is a preliminary announcement. Changing winds or late-season melt could still reduce the Arctic ice extent, as happened in 2005 and 2010. NSIDC scientists will release a full analysis of the Arctic melt season, and discuss the Antarctic winter sea ice growth, in early October.  <\/em><\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>The National Snow &amp; Ice Data Center has declared that the Arctic Sea ice extent has reached its annual minimum and is now starting to expand.
