Glaciers in Norway, Alaska, growing again
From Watts Up with That?, November 27, 2008
Scandinavian nation reverses trend, mirrors results in Alaska, elsewhere.
After years of decline, glaciers in Norway are again growing, reports the Norwegian Water Resources and Energy Directorate (NVE). The actual magnitude of the growth, which appears to have begun over the last two years, has not yet been quantified, says NVE Senior Engineer Hallgeir Elvehøy.
The flow rate of many glaciers has also declined. Glacier flow ultimately acts to reduce accumulation, as the ice moves to lower, warmer elevations.
The original trend had been fairly rapid decline since the year 2000.
DailyTech has previously reported on the growth in Alaskan glaciers, reversing a 250-year trend of loss. Some glaciers in Canada, California, and New Zealand are also growing, as the result of both colder temperatures and increased snowfall.
Ed Josberger, a glaciologist with the U.S. Geological Survey, says the growth is “a bit of an anomaly”, but not to be unexpected.
Despite the recent growth, most glaciers in the nation are still smaller than they were in 1982. However, Elvehøy says that the glaciers were even smaller during the ‘Medieval Warm Period’ of the Viking Era, prior to around the year 1350.
Not all Norwegian glaciers appear to be affected, most notably those in the Jotenheimen region of Southern Norway.
