Having photographed Briksdalsbreen glacier each year we did research there it is now possible to see each year’s retreat:
This photo shows that the ice has melted back to the bedrock and has lost around 100m in one year.
If you visit the area please take a photograph from the big round rock on the moraine just as you approach the lake from the end of the track and post it on Flickr – that helps to provide even more records for researchers! The early photo may have been taken from a different rock as the glacier was so much closer but the rest are all attempts at a fixed location (given three or four different cameras over the years!). You can see this glacier on air-photos half way across the lake.
Some people look at these pictures and say they are fake – but this is happening all over the world. Recent time-lapse photography work shows this very dramatically. Glaciers melt and grow but this speed is unprecedented.
