Arctic Sea Ice Growing Strongly

Reporting Climate Science

Daily data on Arctic sea ice extent shows that the area of ocean covered by sea ice is growing more strongly than in recent years.

The latest report from the US National Snow and Ice Data Center (NSIDC) – see below – confirmed that sea ice extent in October remained off the floor. 

On 3 November 2014 NSIDC data shows that Arctic sea ice extent reached 9.7 million square kilometers – the greatest extent for the 307th day of the year since 2001. This can be seen from the NSIDC’s computer generated sea ice map for 3 November shown on the right (top image).

This follows on from a strong growth in October which confirms that Arctic sea ice extent so far this autumn remains some way above the floor for the month of October recorded in 2007. The trend in sea ice extent has improved throughout October and into November, according to daily data from Multisensor Analyzed Sea Ice Extent record known as MASIE. This improvement can be seen in the graph labelled Figure 2 on the right where the blue line representing 2014 rises rapidly from the minimum in September and is now within two standard deviations of the long term average – that is, statistically in line with the average.
