High snowfall and cold weather to blame
I first posted about the growing Alaskan glaciers back in 2008. Funny how the media seems to have ignored this.
16 Oct 08 – A bitterly cold Alaskan summer has had surprising results. For the first time in the area’s recorded history, area glaciers have begun to expand rather than shrink. Summer temperatures, which were some 3 degrees below average, allowed record levels of winter snow to remain much longer, leading to the increase in glacial mass.
Since 1946, the US Geological Survey (USGS) has maintained a research project measuring the state of Alaskan glaciers. This year saw records broken for most snow buildup. It was also the first time since any records began being that the glaciers did not shrink during the summer months.
Those records date from the mid 1700s, when the region was first visited by Russian explorers.
According to glaciologist Bruce Molnia, a difference of just 3 or 4 degrees is enough to shift the mass balance of glaciers from rapid shrinkage to rapid growth. From the 1600s to the 1900s, that’s just the amount of warming that was seen, as the planet exited the Little Ice Age.
Molnia says one cold summer doesn’t mean the start of a new climatic trend. At least years like this, however, might mark the beginning of another Little Ice Age.
Thanks to Wanda and F. Guimaraes for reminding me that growing glaciers now seem to be the trend.
