The latest daily arctic sea ice extent chart from IJIS shows the current year ice extent at the highest level in the record back to 2002. (2003 was missing).
This represents an increase of 655,781 square kilometers over last November 7 or 7.4%. Side-by-side images from the Cryosphere show there is more ice on both the Pacific and Atlantic side this year. This is 44 days before the start of the Northern Hemisphere winter and 5 months before it will peak.
