The average retreat rate is similar to the rates in 2008 and 2009 but  smaller than in 2006 and 2007. The glaciers measured comprise 14 percent of the total glaciated area in Norway. The mean length change for 25 glaciers in the periode between 2000 and 2010 is 190 meter. This is on the average three percent of the  total length of these glaciers. If the glacier area decreased comparably the total area of the Norwegian glaciers decreased by 80 km2.

Around Jostedalsbreen seven out of nine glaciers retreated. Bødalsbreen in Stryn and Nigardsbreen in Luster retreated 65 and 39 meters, respectively.  Briksdalsbreen showed a small advance of eight meters.

Four out of five measured glaciers from Folgefonna retreated. Bondhusbrea in Kvinherad and Buerbreen in Odda both retreated 28 meters. Bondhusbrea has retreated 325 meters since 1996, and Buerbreen  has retreated 255 meters since 1998. Both glaciers were approximately 775 meter longer whe length change observations were initiated in 1900 and 1902.

At Hardangerjøkulen, Rembesdalsskåka in Eidfjord retreated 14  meters and Midtdalsbreen at Finse in Ulvik retreated 34 meters. Rembesdalsskåka has retreated 343 meters since 1997 and Midtdalsbreen has retreated 143 meters since 2001.

In Jotunheimen annual changes are smaller. Six glaciers melted back between 5 and 20 meters. These glaciers have retreated 35 to 80 meters during the last 10 years.  kortare. Hellstugubreen and Storbreen have been monitored continiusly since 1901 and 1902, respectively, and have retreated approximately 1100 meters in this period.

In Møre og Romsdal,  Trollkyrkjebreen in Norddal has retreated 16 meter since 2008. The glacier retreated approximately 140 meters between 1993 and 2008. 

In Nordland, four glaciers are measured. Storsteinsfjellbreen in Skjomen retreated 22 meters since 2008. Betweeen 1993 and 2008 the glacier retreated approximately 130 meters. Austre Okstindbreen in Rana retreated 32 meters since 2008. Engabreen, an outlet glacier from Svartisen has melted back eleven meters, and 266 meters since 1999 when thee last glacier advance ended.

In Troms and Finnmark four glaciers are mesasured. Steindalsbreen in Lyngen meelted back 40 meters, and it has retreated 221 meters during the last ten years. Koppangsbreen and Sydbreen melted back 18 and 10 meters, respectively. An eastern outlet from Langfjordjøkelen in Loppa in West-Finnmark melted back 15 meters. This glacier retreated 336 meters during the last ten years.
