\n

We noted<\/a> earlier that the Artic sea-ice is approaching a record minimum. The record is now broken, almost a month before the annual sea-ice minima usually is observed, and there is probably more melting in store before it reaches the minimum for 2012 – before the autumn sea-ice starts to form. <\/p>\n

\"\"<\/a><\/p>\n

The figure shows annual variations in the area of sea-ice extent, and the x-axis marks the time of the year, starting on January 1st and ending on December 31st (for the individual years). The grey curves show the Arctic sea-ice extent in all previous years, and the red curve shows the sea-ice area for 2012. <\/p>\n

(The figure is plotted with an R-script<\/a> that takes the data directly from NSIDC<\/a>; the R-environment is available from CRAN<\/a>)<\/p>\n

UPDATE on the update<\/b> The National Snow and Ice Data Center announced today (August 27th, 2012)<\/a> that the 2007 record has now been broken by their more conservative 5-day running average criterion. They also note that “The six lowest ice extents in the satellite record have occurred in the last six years (2007 to 2012).”<\/b><\/p>\n\n<\/div> ","protected":false},"excerpt":{"rendered":"
